Veterans please help!!

I have tried everything g to get this issue resolved, and still no luck.

Can anyone tell me if this is calcium deficiency or what exactly is going on. It’s not wind burn or light burn as I’ve tried fixing those two things. I’ve flushed the soil with plain water. Someone please help!

Howdy Greenlivin, It could be from a pH problem. When the pH is 'off', it can appear to be a mineral deficiency problem.

Taco leafs say light/heat stress, leaf colors say ph or root issue IMO.

It looks like a ph problem to me as well. Normally brought on by over feeding. I would try flushing with plain ph water then about a half gallon of 1/4 nutes ph between 6 and 6.5 remember that the leaves don't repair themselves you have to judge things by your new growth or if things get worse
good luck

Tersky is right, those top leaves looking taco’d. CalMag deficiency could be from low ph. Could try flushing at a higher ph with CalMag.

I flushed the other day and it was coming out at 6.0. 6.2 is ideal for calcium, so I watered again today with a ph of 6.6 and doubled the cal mag dose. Aside from the cal mag, this is an organic grow so I’m not worried about over feed. I’m keeping the light at recommended distance, and have raised it a little more. Temps are 70-79 F so I don’t think it’s heat stress either. I’m thinking it’s calcium deficiency due to where the symptoms show and the 6.0 ph for run off.

Appreciate everyone’s input. Just wanted to make sure I wasn’t missing something.

Looks like a lockout to me. = Showing deficiencies.
if you already flushed the soil and gave it some cal mag - It should be all good again. And you adjusted the light height, so you shouldn’t either get “new” taco leaves.

The affected leaves will never turn normal again. Is it growing normally? Or is it stunned a bit ?

[Greenlivin]

It’s an auto in mid to later flower so really just bud bulking and that seems to be going normal. The taco leaves really progressed over the past 4 days, Along with yellowing leaves. Hoping to see some difference the next few days after increasing ph and cal mag. Do the brown spots point to a calcium deficiency?

[CaptainWiese91]

The flush should make it good again.
Yea the brown spot could easily be cal mag problem - but also just a lockout.

It should be getting better now
