Nitrogen toxicity?

RallyAutosstarted grow question 6y 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.

Orange dots Too much stress and light maybe? Should I use a little bit more of CalMag for this lady? This is a Mexican Airlines on day 12, topped. I know these are really small dots, but I like to prevent.

Accidentally ripped off a fan leaf ='(Hi there, Today I was screwing around with photo seeds in rapid rooters and I moved a sticky bug trap that landed on top of my 12 day old plant and ripped a fan leaf off.. I just wanted to check with others to see if this would cause a lot of stress or stunt the auto? Thanks!

I've seen that some growers trim the tips of the leaves. At what stage and for what purpose is this done?

Nute burn or light stress Wondering if I’m pushing them too much or if the brown rust spots are from light stress? Seems to only be on the top half of them and showed up right when the stretch slowed/stopped.
