HELP! Leaves are 'clawing'

[nOtH1nG]

Hi so i had this problem with the leaves looking droopy and 'clawing' and i searched and realized that was nitrogen toxicity, so i watered them with only ph'd water at 6.20 2 days ago, should i continue to give only water? Cause some of them are already looking better.. Here's some pictures, what do you think?
Thanks

I would raise your ph to 6.5 and mix in a shot of cal mag. Your soil looks to be pretty dry so keep that in mind. For the most part your plants look great.

Nitrogen toxicity is kind of rare to see. I’m not saying you are wrong.... 9 times out of 10 this is a symptom of overwatering.
do you let the medium dry out before the next sequential watering? If you are doing that already... try less volume of water.

yes they dry in every 3 days, im watering with 400ml of only water to get a little run off from the bottom, the fabric pots are 3L..before i had little run off maybe thats the problem the nutrients "locked down" in the pots
edit: watering today should i give only ph´d water again?
thanks

I don’t think nute lock out or toxicity is the issue. Try less than 400ml next watering.
I would feed them nutes as usual. Maybe 1/2 strength if you are concerned about salt build up.

I agree, doesn't look like a nitrogen issue...

i did 300ml of 1/2 nutes lets see how they respond, also tested the ph of run off and ppm its 6.8 and only 150ppm, dont know why some are so green and look like overfed or overwatered( the soil dries every 3 days too)..hopefully they will go back to normal
edit: they already started flowering but it took 2 weeks after i switched 12/12 i then noticed that some light was entering in the growroom in the dark period could that cause this issue?
thank you

Yes, light leaks in the flower room can cause issues. It really depends on the intensity of the light though.

 

[nOtH1nG]

It was Light from outside, daytime.. Because my Light cycle is from 8pm to 8am..wasnt intense though

They are looking almost the same but the top looks like its whitening a bit and the bottom bud sites too, the lights were 50cm from the plant, i raised them to 60cm now, it could be Light burn( i have 2 1000w Led Light)

Looks like things are improving. Give them some time. If you can give them less water with out drying them out to the point where they look sickly... go for it!
