help ! my plants are dying

[buddymag00]

im 6 weeks into 12 week flower using 2 topfeeder hydro buckets . leaves started turning yellow and falling off. i had been using full strenght nutes (in accordance with directions on bottle. i flushed for just 1 day then reduced the nute solution. the plants are sick ! new leaqves around the young colas are yellowing and dying there is barely any leaf left . my ppms at the mo are around 500.i feel it is from over fert. should i flush again for longer or add a ripening agent to cut my losses . will add pics soon . my main question is when is the plant too far gone for recovery. bottom leaves yellowed first ph kept around 5.8 . please help i am distraught.!

this is a pic taken a week ago wheneverything was fine.my camera is on the blink but the plants are devastated since

I would flush using a product like Clearx for about 1 and a half hour to remove nutrient buildup in the medium. Then fresh water for a day or two. What nutes are you using? Are you using a Cal-Mag type product? Tap water or RO water? How are the temps in your room and what is the humidity?
More info is needed to give you an idea of whats going on.

 

[buddymag00]

no cal /mag product. tap water left to evaporate off the chlorine.nutes;dutch formula. temps around 19/20 c humidity not sure very good extractor fan. the leaves are also curling like claws , drooping , yellowing. even the colas look sick and are keeling over and look weak. i think the ppms were as high as 1700 before the flush

 

[resinryder]

Which strain/strains are you running? Someone here that has run the same strains may be abble to help with nute requirements. 1700 ppms is very high for most strains. Granted some strains can take that and higher and do quite well. Others don't.. Temps are good no problem with that. Claw leaves are usually a sign of nitrogen toxicity. And can also be caused by too rich of a CO2 concentration in the room if CO2 is used. PH is good.
Think overall you've feed them to much. Back off and flush with plain water for a couple of days. Pour off the water each day and measure the ppms of the run off. When the ppm's are close to the same on the runoff as the feed water they have been flushed well. Clearx type products will leach out the nutrient buildup in the plants.(I use it every 4 weeks to leach out the buildup in my rockwool cubes.) CalMag products will aid in keeping the Calcium and magnesium(sp) in check. Most nute products are lacking in these 2 elements and marijuana plants need it. 2-3ml/gallon usually do the job, but up to 5ml/gallon will work fine also. Calcium deficencies show up as the leaves start loosing their green color and begin to yellow. Usually from the top down.
When you get them flushed well, add your nutes to a weaker strength. Say somewhere in the range of 900-1100ppm's. You can always go up but it's hard to straighten out if you go to high.
Good luck with them.

thanks resinryder , the strain is nlxneville haze , it is sat dom. i have been advised that sativas eat less , and can be cranky above 600ppms in flower. this is far less than the bottle directions! i really feel a sense of loss hope the flushing and adding some cal/mag product will save my girls. will have to wait till mon for hydro shop to open. i will follow ur advise with the pour off every so often until i stablize. thanks fr your help my friend.


aint over till the fat lady ripens !
peace

Bottle directions can very often be misleading. Always begin with about 1/4 strength and go up from there as the plants tell you, not the bottle. If you're being told the strain likes it around 600ppm's start there when you go with a new nute mix. You can always bump up without a problem. In hydro, the leaf tips are your best indication of how you're growing them. Just a slight burn on the very tip of the leaf says you're cooking em just fine. After a res change it can take several days to see any problems unless the mix is very hot.
Good luck with getting them back in shape.

thanx res ! funny enough the leaves have not burnt as such they rae just turning pale yellow n falling off. since i started flushing 1 plant has started to recover n the other is still deteriorating (the colas included) they started shrivelling as well but there are no spots or concentration to th yellowing , seems to take the leaf as a whole.
PS i know im pissing against the wind without pics so ill have them up asap. again thnx for help

do you mean cal/mag sophisto? the roots are good

i have flushed for 2 days now. one plant has recovered but the other is nearly dead with id say less than 30% of its foliage left. ihave given each plant a dose of revive from advanced nutrients. more for the one that needs it most . i have also purchased a bottle of ripener to save something from the nearly dead plant if needs be.
