Hey, I’m not an expert but that doesn’t look like light burn to me since it’s affecting only the lower leaves and typically light burn is on the upper leaves also they will start twisting if the light is too much. Do you have a fan blowing on it? If so move the fan to the other side. I have also seen that when I don’t use enough calcium and/or magnesium. I also am having a similar issue on a mother plant of mine someone suggested it was root bound or over/under watering.

Hi @trev530

Looks like you have a pH root issue or a nutrient problem. I think you have caught it early. Have you tested your pH?

I have the run off is hella high but im putting 6.0 in so idk these motherfuckers are at a Cal Mag problems since the beginning I thought it might have been light toxicity due to the other plants starting to Taco I caught that shit though early and I moved the lights up now they’re about 19,000 candle feet or lux it started to happen when I turned the intensity past 50 on my light and when I had a new light that didn’t have a dimmer it’s just 100% with red lights and blue lights or 100% without them so I lifted that shit until my meter read 19 thousand foot candles or Lux hopefully that’s the problem or calcium magnesium deficiency to which I gave it some thank you guys for your help I highly appreciate it

Prolly root issues if everything else is “okay”. If the roots and messed up and burned from over/under watering and/or improper mix of cal/mag, if its cal/mag related it could have been caused by bad/cheap coco coir. It will only get worse when they go into flower, if they were mine I would shred them for clones and toss the plants. if you fill out the check list @nacho151 provided it will be easier to figure it out.

Ok grow fam i figured it out i had my lights way way too close. I looked at a billion pics of every deficiency and the one I could match it to the most is the light deficiency because of the new shoots coming out they’re all dumb looking and bleached and then I seen another picture that look just like mine and it said light toxicity I was like dude the leaves are all skinny and weird looking on the top just like mine anyways thank you all for your help I moved my lights now they’re at like 18,000 or 19,000 LUX
