sick plant

[greenie]

anyone got any ideas on remedies? It may just save thise big girls life. Hindu skunk, 4 weeks into flowering. problem showed its ugly head yesterday evening. I pulled off all the sick fan leaves. No other plants in the room are sick. The infection is on the tops of the leaves, which leads me to believe it is a fungus attack. Any solutions? this girl is 24 hours from execution.

looks like nute burn to me I would flush the ladies with a few gallons a freashe water!

major moisture stress for one thing but do you have any pics of the affected leaves? all i see in that pic is too high a relative humidity (lack of trichomes) and severe moisture stress (ie: under, then over watering, etc etc) its a root based problem, the weird leaves there. possibility the lights are too close too causing radiant heat stress/damage but again need more/better pics my man
pH can do it too tho i suppose but since you removed the leaves we have no way of knowing unless you have pics or can tell us more about what kind of nastiness was on the surface. was it white? if so it is mildew and even if its not i suggest stablizing RH at about 40% this late in the game if you want weed with even halfway decent trichome-coverage hindu kush crossed to skunk should be showin off her frostyness by now to some degree...i see none

ps- what do you mean by 24 hours till execution? i hope you dont mean harvesting! that plant isnt even half done!!!

be well and hopefully ya get up a better description and or better/more pics how about a full plant shot at least? also a brief rundown of nutrient regimine, soil mix, pH of water before mixing nutes and after then a pH test of the run-off would be great help to us/you. also and most importantly we need to know the environmental stats such as RH and temp .

thanks.

oh, and what are u using for FEA?

how is that nute burn? which element are you thinking he overdosed on?

'flushing' is the wrong word, btw, (proper terminology for what u are trying to convey for your scenario would be 'leaching')
'flushing' is typically referring to when yer doin a week or 3 of plain h2o with no nutrients added in order to 'flush' the residual nutrients out of the soil/reservoir nearing the end of the cycle so yer bud burns to a white ash and not a black coal.

anyway, it doesnt appear to be nute burn from here, but more pics will tell the story.

hope this helps and i apologize that i had to correct ya, but its just bad advice at this point considerin the extreme moisture stress already!

shake it ez

[greenie]

possibility the lights are too close---Nope. all other plants are fine and they are scrogged.


nothing is visible on any leaves, but the leaves look fine on the bottoms and the chlorosis is starting on the tops. the RH is stable at around 40-50 BUT the room temps are high. when the lights turn off, the room is vented constantly and the humidity only rises to around 50.


I know its not done, bu i WILL not contaminate the whole room because of that one plant, nice as she is.

Nutrients are as follows: 1 gallon per plant every other day. nutes are:
1/2 strength optimum hydroponix a and b for flowering
full strength cal-mag booster
1/3 strength 0-12-2 guano
full strength AN big bud

Soil-less mix consisting of 3/4 coco 1/4 perlite

PH approx 5.5-6.0 before watering. have not monitroed runoff but will. i am using run to waste.

The FAE is constant and there is a co2 enrichment system. The Large fan leaves were the culprits, no small laves or buds are affected (yet). H stays around 50% or less and temps around 90 during the daytime (hot, i know) and around 72 at nite.

ill post some more pics

[greenie]

heres more pics of the sickling. she was under the 600w hps in my coco grow

[greenie]

also cap... the reason i know this is disease and not nute/room/condition based is i am growing 10 other clones in identical conditions. the under/over watering may be correct though as the plants are a little large for one gallon gro-bags

[greenie]

there are trichomes developing, if u check out the 3k hps coco grolog there are pics of everything. they should be done in around 3 weeks.

[greenie]

heres some more pictures. it had all of its fan leaves up untill yesterday when many of them were pulled off in a very rapid fashion. save her life! dont let her die in vain!

PS: the first pic is an average nugget right now on a healthy plant.

[omentheduck]

I am not sure exactly which I would say it is, not sure how to tell exaclty either? But I have had in my experience nute burn after a does of way to concentrated nutrients , act exactly like this , admittedly there was a ph and nute lock out to issue too there.
and true flushing is the wrong word to use, It's kinda on the boarder with this one, and i guess I should have explained it, to do it every regular watering, a course of days running a few extra gallons thru it to see if it can help leech out the stuff so in a way flushing just not the final one.
and on the leeching don't you still use pure water( distilled is better, nothing in it and has a neutral ph) .
and your right the more i look at it I don't think it is either their should be a little yellowing ( i think ) for nute burn and np on the correction don't need to give wrong info and have a even sicker plant , plus it let me look back on it to see that the judgment was to hastily made ! lesson learned but on the flushing leeching it a by product of flushing it.

are the fan leaves growing curled befor they shrivle?
and in my room I have two plants in the same bucket of the same strain and one if curling like hell the other is one of the healthiest I have? some have different needs I have leeched the soil by flushing ( not the final flush) with 2 gallons for every gallon of soil every watering so that it would happen slow and it is clearing up!

[greenie]

they shrivel and crunch and curl within 24 hours. plant has not progressed any since yesterday.

[omentheduck]

If i hasn't gotten any better the only thing that i can think of except of going down the check list is to try and get it by it self so that you can control it and make every thing fresh with no nute and try to build up from there! This is what I would do but then again I would also like others input on this to help any issues with it.

Could it be a fungal problem in the soil? Might want to consider a hit of copper on the next watering as a last resort.

[greenie]

cap said it seemed like something in the soil. I will add copper to this next batch of nutrients, and that plant will get a heavy dose of hygrozyme.

[greenie]

the plant is currently removed from the horticultural netting and is near the extraction fan

[morbid]

hygrozyme will do very little for this plant - useful as it is

I'd pull her out - if it is viral then your other plants will suffer (maybe already have)

Your other plants look fantastic - I personaly wouldnt risk their health over this one. Your enviroment settings sound fine. Do you have a chamber you can flower her in alone??

[lifestream]

that might be zinc or calcium deficiency..

edit: what color is it changing to before dying off? is it mostly near the tips of the leaves and just the top? also, does it look like yellowing or burning? can't really tell with the pics.

[greenie]

it changes to brown/green from the tips to the inner vein. One thing im sure of, its not a calcium deficiency as i add a calmag booster every watering. maybe an excess. i will be changin super blooms tonight also. The plant is still isolated. it is not getting better but not getting worse. i will take pictures under normal light tonight.

[greenie]

all the large fan leaves on the whole plant have been removed.

[lifestream]

deficiency is normal during the flowering process, by the way. if ur girl continues to stay stable, i wouldn't worry about it. if she gets worse, post pics and details, please.

[greenie]

the disease has spread to more plants. they are in the early stages and i will take pics as soon as i am done watering
im starting to freak out and have cut the lights back to 10/14.

[Lazlo]

Shit, that ain't good! I wonder if the coir has bloomed with trichoderma? Have you dug down into the soil a bit to see if there's any mold mycelium?

[greenie]

godDAMNIT that plague is spreading, and its not a contact spread either as the newest victims are several plants away. The only thing i fucked up on lately was leaving runoff water in my tables overnight a few times recently. Could this be the problem? The sick plants are all near the drains. heres more pics of the sickness.

PLEASE PEOPLE i need some ideas. should i kill all the sick ones? Ive already swtiched my nutrient regimen to a non organic mixture and i oulled the first sick one out of its growbag. the roots looked ok??

[greenie]

do u think i should rip apart that one bag ? ill do it right now if u say

[Lazlo]

I suppose it wouldn't hurt. You could just slit the bag halfway to see what's going on in there and then pop the whole works into another bag. Double bag it.

[suckerfree]

relax friend. i've had worse looking plants make it to the end before... i'd wait a little longer to see where this is going before giving your friends the axe.

[omentheduck]

can you smell mold or anything other than ganja?

[omentheduck]

anything in the soil?

[Lookyhere]

Ripping off the fan leaves is a mistake IMO. when there are problems with over/under watering, nutrient poisoning (too much), or ph problems, etc... A lot of times the plant will sacrifice the fan leaves to allow the healthyness to stay in the most important part, the flower. By removing the fan leaves, 1. the plant doesn't need as much nutrients (depending on how many you take off), 2. the plant now has less stuff to sacrifice in order to keep the buds healthy. I don't think that your plants are diseased.

[Lazlo]

Hmm, those look either over heated or over lighted.
