sir_isOanswered grow question 3 years ago
Eh, looks like slight nitro deficiency, but those are also larger/older leaves and the plant is maturing so it's likely minor.
The8thChevronanswered grow question 3 years ago
Could be either. Looks closer to deficiency imo but both can look the same.
Take the EC and pH readings of your feed and runoff. If the EC is much higher in the runoff, you have a lockout of some kind. If your pH is off, then your plants may be incapable of taking up the nutes you provide. Recalibrate your pH meter before testing again. If it's one of the yellow ones, consider throwing it out in favor of a brand like blue bluelab or apera instruments. It's worth the investment!

Classic N toxicity (:Heyho :) since she has progressing leaf tip burn and curled tips which I'd almost certainly say is a nitrogen toxicity, would you recommend going down to 50% general strength or maybe leave out the grow supplement at all and just feed Bloom? Cheers guys :)4 years ago

Deficiency?I laid off the nutrients last week after some concern that I was overfeeding, but I think that resulted in a deficiency. (Some of the darker colors might be related to the strain? π€)
The third picture was taken 12 hours prior to the first two, so it progressed quickly overnight

Too much light???Do you guys think she is getting too much light?
EC is no higher than before, but Iβm starting to see yellowing of the tips... old and new leaves.
It seems to me the leaves look somewhat anaemic in general.
100w LED was about 14β- 16β. Now its 19β.

Early nite burn?Hello! I've noticed that many of my leaves have burnt tips. I first noticed this about 3-4 days ago. Since then, more leaves seem to have this but the it hasn't gotten worse on individual leaves. Could this be nute burn?
Thanks in advance!

Magnesium or Nutrient Burn or?Magnesium deficiency, or nutrient burn or??? Only on the lower leaves so far, curling down was existing genetics - but the burnt tips are new and some have even curled up now. Probably 5+ weeks left so too early for natural dying off?
