Twisting leafs?

[Pakweezy]

I am bringing this plant back from nut burn/light burn...it was doing good but now I see that the leafs are starting to twist and some still point down...when I water the ph is 6.5 and I have it under a mars hydro 300w led light have light about 20" away I have also used low stress training and tied it down in a few places plant is around 6 to 8 weeks

I don't see anything that I would worry about. Maybe put some pictures in normal light. And if you have corrected the nutes burn all is good! Does that happen to be northern lights?

[Pakweezy]

No it is not northern lights to tell you the truth I do not know what it is got it from some green I smoke along time ago...

My twisted leaves turned out to be a calcium deficiency. The spots didn't show up on the leaves till a few days after the leaves got twisted.
I did have calcium in the soil, but my PH got too low.
I am not telling you what to do, but just sharing my experience with twisted leaves..

I need to water today do u think I should give it a little fert i have not givin it any after I noticed the burn

Do not back off nutes. Burn is a baseline. You know what your plant can take now. Feed!

The color does look a little off in natural light, almost sort of bluish, like the pH is off. It's pretty dark so I'm not sure it needs overall higher levels of nutrients, especially if you're in soil which will naturally contain some amount of nutrients. When plants are low on nutrients they tend to get pale all over or get covered in spots/deficiencies, not dark green without many spots. What is the pH of the water that comes out the bottom? Is it coming out higher or lower than 6.5? What growing medium are you in, and what nutrients are you using? If you're worried the LED might still be too close, it can't hurt to move it up another inch or two just to see if that helps. Overall it doesn't look too bad

The last time I checked the run off the ph was correct and I am using a organic potting soil and using a fert the is for tomato's this is my first grow trying to learn as much as possible so my next grow I can get it better
