Nitrogen toxicity?
RallyAutos
started grow question 5y ago
Are these dying leaves a result of the nitrogen toxicity or something else? Thanks for all your help!

Could be really bad light stress... My guess would be that a high PK nute has locked out calmag and other micronutrients. If you're using a booster, roll it back a bit. As always, check your pH and EC going in and coming out.

I had this before and although not entirely sure I put it down to a pk overdose. N Overdose looks very different - dark green claws.

Quick question is this the color green I am looking for my leaves to have throughout the whole grow? My last one I over fed under fed too many nutes and my leaves were a dark green which to me being new thought that was good when it wasn't. Advice and input greatly appreciated.

Problemas de ferilizaciĂłn?
Que opinan sobre está carencia/exceso en estás plantas? Ambas tienen 4 semanas y han mostrado esos indicios solo en las hojas viejas, pienso que puede ser dĂ©ficit de calcio/magnesio, aunque no controlo pH, asĂ que es un factor que tambiĂ©n quizás deberĂa considerar. Que opinan?

What is going on with the Special Kush? Check out her sugar leaves - and it's only on them, it's not in the buds and it's not on the fan leaves. Deficiency? The other plants don't have it. Some kind of fungus? I removed all leaves that had it, and it returned on the other leaves.

Dark ends of leaves
Dark patches towards ends of leaves? Thought maybe nitrogen toxicity, but they don't seem to be turning yellow or curling excessively. Maybe it's compelled completely normal?

Brown spots due to light height?
Brown spots on a few leaves close to the light that had yet to be super cropped to control height. Not noted on lower leaves. Temps/humidity OK, no changes in nutrients. Thinking this could be from being too close to the lights, but would appreciate some expert feedback. Thanks!

Is this self topping ?
I've just noticed that my Lemon OG auto has no top, I'm guessing this is what self topping is. I've heard about it before but never experienced it. Have any of you encountered this before and what are your thoughts on it, is it beneficial or a disadvantage.

Been struggling with leaf issues for weeks. Initially thought lockout due to N toxicity. Plants improved after flush in Week 7 but then promptly started worsening a few days ago. Is this a continuation of a lockout issue? Would you feed? Flush? Advice is welcome! 🙏

Fertiliser burn
A few leaves of my bush have this little brown spots on them, I googled this and made a conclusion that it is a fertiliser burn. I assume it was done with “Root booster”. Can I continue using vegetation fertiliser? Do I need to remove damaged leaves? Any other actions needed?

Plants are burning part 2
Added some Bud Boom (0-40-23) to give a kick of phosphors…. Most of plants are turning yellow and burning that’s problematic ! What’s about phosphorus with my watering ? Maybe Cal-Mg? Or even are the roots to compact on the bottom of the pot ?
