    I've recently repotted a couple of my plants and they seem to be growing better but one is being strange. I thought it might be nite burn, but I am pretty sure I didn't get any on its leaves. Any help on the subject? I plan on cutting those leaves off. Also any advice on trimming? I have been thinking about cutting some of the more yellow/whitish leaves.

    Looks like overwatering to me with the leaves pointing down my friend.if the yellowing started from the tips and worked down i would also say nitrogen toxicity.

    OK, so could nitrogen toxicity be causing the brown spots? Also how do I counteract the nitrogen toxicity? I thought flushing would help with that which is why I recently watered the hell out of it. My real concern is the brown crispy bits. I didn't think that nitrogen should cause those spots. Although I'm a novice, so I'm not too sure. Lol. That's for the reply though.

    No problem man. Well the drooping leaves indicate over watering. how are your stems? if theyre easy to crush or "weak" thats a sign of N toxicity. if they were a heavy dark green and then slowly began to yellow once peaking the "dark green" color then most likely N poisoning. Just lightly water since youve been flushing but not until at least top 1inch of soil is dry. keep an eye on effected leaves but most dont recover if really yellow and brown. but new growth should come out a nice green,not to dark.

    The stems are super hardy. I think almost too hard. But I genuinely think that the nitrogen might have been a problem, but it's been flushed and it's looking better now. Except for those crispy brown bits. I cut them off today and am hoping they won't come back. But what I really need to know is how they got crispy. Now that I'm thinking about it, there was a point where my heater stopped working and it got to like 45 degrees in there for about a day. I don't think that's what caused it though.

    its common for the leaves to go from a lush light green to dark green to yellow to brown. i wouldnt worry unless other leaves begin to do the same after your pruning.

    Since I've trimmed her she's looking alot better. Still a little yellow but no new growth is yellow. I'll post some more pics of her tomorrow. Thanks for keeping up on it. You're the man.

    ALWAYS turn OFF the blurple LED lights and HPS lighting and give us real normal lighted picks.

    You over fed somewhere and it gave you pH and lock out problems.

    You say new growth is looking good? You did something right and she got out of it and is growing right again.

    I learned re-potting always caused burning, even with PH and clean water. Took me 3 plants to realize. Once I stopped transplanting, I stopped burning. New nutes in the soil feeding into the plant causing burn. ( from my experience ) Im no master grower at all Also I would keep any leaves on that do not fall off when you touch them, even if they are slightly yellowed. Look outside at trees ( well if your in a area with trees ) there are leaves dying off all the time.

    Hmm. I transplant often and don't see that problem. What kind/amount of bites you usin man? Also I'm pretty found of pruning leaves here and there as long as it's veg and not anytime close to flower. Still, it's weird you have nite burns from transplanting? Can you elaborate your methods? Interesting.

    Your doing something else wrong at up-potting! I up pot 2 times after the solo cup and I haven't gotten any "burning" in over 40 years of growing! What soil are you using?
    What do you water it with after the transplant?
    Use some nutes then?

    I just watered them with my well water. No nutes after transplant. Honestly I used some pretty cheap soil call "Earthgro". The burns have totally stopped but the yellowing is still pretty annoying. My camera isn't working right now, but I'm trying to fix it and I'll have some new pics up soon. (Hopefully)
