Hello all. This is my 2nd grow. I have 6 plants entering week 6 of flowering. 3 of the 6 plants are doing GREAT... The other 3, not so good.
All leaves are becoming VERY brittle and curling (some curling up & some curling down) and eventually drying up completely and falling off.

I am growing in 1/3 peat moss, 1/3 perlite, 1/3 vermiculite in 5 gal pots
2 400w hps lights about 14 inches away from plants (air cooled)
I have been using FOXFARM GROW BIG & BIG BLOOM until i switched the lights to 12/12. After feeding them the TIGER BLOOM in flowering stage everything was going good. Then feeding them the TIGER BLOOM a second time is when I noticed all the unhealthy leaves.

Is this nute burn? Nute lock? Calcium deficiency? PH problem? Im stumped... PLEASE HELP

Tiger Bloom is hot by many accounts. Check ph, do you use calmag? Rootbound? all same strain? I still add N the first few weeks. Your soil has almost zippo except for what you feed.

I have had similar issues before, look at ph. I was using sunshine advanced #4 and which is a peat moss and coco choir mix. They mixed dolomite lime in to counter the decomposing of the peat. I found that it needed more about halfway through flowering because the ph was too low as the lime washed out and more peat decomposed. Also I found that Tiger Bloom is pretty acidic. Starting with tap water at 7-7.2 ph and adding tiger bloom brings me to about 5.5 usually. I shot for 6.3-6.5 for a ph and that corrected my problems. I have since gone back to soil until I have time to give hydro some attention.

Do you foliar feed you plants? it looks like nute burn from foliar feed. That's my best guess.

I had the same problem and asked the same question. I was advised to keep running the grow nutes for the first 2 weeks of flower before switching over to the bloom nutes and it worked like a charm. Coho above is saying the same thing basically with running the N for a while into flower.

Oh yeah, I would guess your too heavy on the nutes which is typical for new growers. I did the same thing myself last year. Cut the nutes down to half the dosage and you'll see a big difference although the damaged leaves wont recover.

COHO - I Adjusted my water's PH to about 6.1 - 6.2. I do use CALMAG about every 2 - 3 waterings. I am growing 3 different strains (2 of each) White Rhino, Phatt Fruity & 2 seeds I got for free with my order (the 2 free seeds have done the best this grow & my first grow for some reason.)

DEE TEE - I did foliar feed the plants until about 1/2 way thru the second week of flowering.

COB NOB - I have been told to perform a flush before switching to 12/12... Is this accurate?

i reckon your ph is to low get it to about 6.5 cut down nutes to half strenth and give it a few days , as the boys have said your damaged growth wont fix but keep yer eye looking for new damage ! i think yer plant will get better... good luck pal (sorry make sure you have good drainage)

Don't follow fox farms feeding schedule. Build up to a ppm your plants can tolerate, get familar with nute deficiency/toxicity and learn to feed your girls what they need, not just what a label says. You will also need cal/mag as the ff trio has next to none. A silicon wouldn't hurt either, oh yeah and enzymes.

Don't worry just like your plants you will mature and realize the ff trio sucks. Thats why they have so many other supplements, that are also sub par.
