Need help identifying problem

Hello everyone,

I need your help determining the cause of this problem, which is driving me crazy :wall:

I looked everywhere, showed to “experts”, read articles and still can’t figure this one out. Please help me.

This is White Widow in veg week 3. Grown hydroponically in 6” rockwool cubes under T5 on for 24 hours. Watered every 6 hours for 15 min. Closet temps range between 74-78F and humidity ranges 50-70%, good air circulation and ventilation. Bigfoot A and B nutes, Cal-Mag, Monster Grow, Zone and Sweet – all together 1.57 EC. Had the same problem (plus many, many additional problems) with Advanced Nutrients, so I switched back to what was working for me in the past – Bigfoot. Too bad they are no longer in the business, so I’ll have to look for good replacement nutes.
I flushed it and it didn’t help.

All suggestion and input is greatly appreciated. Here are the actual pics:

Once again, thank you all in advance for your help.

Looks like the claw, too much nutrients. Flush with water and leave it alone for a couple of days before feeding nutrients again.

Did you notice it starting from the top or bottom? any pH problems ? That curling/twisted leaves imo it might be your pH fluctuating too much and that yellowing is something getting lockout out... N? Mg? I'm probably wrong but hope it helps

Joeh3000,

Thank you for your input. It started at the tom and is traveling down. My PH drifts betweeen 5.6-6.0, I adjusted to 5.8 when it gets out of range. I flushed it yesterday with FloraKleen and now it is on RO water with 125 PPM of Cal-Mag.

Does anyone think this maybe due to some kind of inside air polution?

Thanks
