answered grow question 6y ago
If they came off towards the bottom of the plant, it is a nitrogen deficiency. If not, since the yellowing and necrosis begins on the outward edges, I would say it looks like a Magnesium deficiency.

Nitrogen Deficiency?
Think I might have a Nitrogen Deficiency but just wanted to check and confirm with some of you? Leaves are slightly pale and yellow across the plant. I checked runoff Ph last week and it was 6.1 realised it can lockout some calcium so flushed with 6.7. Thanks

Losing vigor and yellowing
Sorry I don’t have a diary for this grow. I did collect some runoff on one of my girls so hopefully this can help for giving assistance. This is only my 3rd grow and the first 2 went very well but this one isn’t, all plants have lost vigor, are growing slowly and are yellowing.

Slight Yellowing on tips of new-growth? (VEG)
Why am I getting slight yellowing on the ends of new-growth leaves? It's affecting every plant. The only clue I have is that it might(?) be related to very cold nights because of my re-vegged photoperiod showing purpling on the edges of its leaves. Any ideas?

Is this more nutrient deficiency?
I believe the yellowing and brown spots came from the roots starting to suck up more water than the previous weeks. Do you agree that the Durban Poison had some nutrient deficiencies?

Manchas en hoja
Hola! Aparecieron estas manchas en una hoja de una GG#4 de zamnesia en su quienta semana vegetativa. No es algo que me preocupe, ya que la planta tiene una apariencia sana y crece vigorosa. Pero nunca vi este tipo de manchas y me gustaría saber su posibles motivos. Un saludo!

Yellow sugar leaves
I am waiting for a low-THC strain to develop amber trichomes and I found two buds with these yellow sugar leaves. There is no bud rot, should I wait longer to harvest? Also, do CBD strains develop amber trichomes, or should I harvest now? Additional details available in growdiary

Late flower issues- chop early?
Week 8 of flower (haven't been best at keeping up with diary). Poor girl is deteriorating rapidly but I don't know why. Too late to fix, but too early for ideal harvest. Should I just let her ride or chop early and try to salvage what I can?

Light or nutrient burn?
Ive been having yellow tips on the tops of both my plants for some time now, I already raised the light up a bit higher than the maximum height the manufacturer recommends, but Im still having the yellow tops. Could this be nutrient instead of light burn?

what's wrong?
this yellowing that starts from the edges and ends up drying out the whole leaf is only happening on the hulkberries (the fat banana looks great) so now I just don't know what it could be 😭
