What are my leaves turning purple/black
Jef79answered grow question 4 years ago
Hello.. Hope u are well.. Its most likely genetics as sum pheno of gelato do have nice purple hues.. It cudb a cooler spot in ur grow space so effecting single plant bit more than others.. I noticed in pictures that ur fan leaves have brown and yellow spots wit slightly burnt tips.. This is due to slight over feed.. If its been warm the plants will drink more water than nutrient and leave ec higher than wot u put in.. Simply lower amount of nutrients uve been giving her.. They look great tho and im sure ull get a great yeild of quality buds.. Gud luck n stay safe.. 👍

BTW It may be more helpful/easier to diagnose if you took pics under white light

Looks like it could just be genetics, but be careful because it does look similar to a phosphorus deficiency if it starts on older leaves first. Some of the others in the background look to have a calcium deficiency.

Nutrient burn, Light burn, or Phos Def? red stems purple bruises,Noticed red lines leaking red into the leaves with purple bruising, and the starter bottom leaves seem to be turning yellow, with the leaves above looking dark green with spots. Is this signs of light burn or nutrient toxicity? And is it lacking phosphorus or just the strain gen?

Color morado en la parte inferior de las hojasAyer hice una defoliación mínima (2 hojas) y al darles la vuelta me di cuenta que están de color morado
El aspecto en la parte superior es sano y normal
¿Esto tiene alguna importancia?
¿Genética?

Red stems and dark leavesThe leaves are firm and not curly, slightly blue-purple, but since 1 or 2 weeks ago the stems have started to become red (Phosphorus deficiency?), so i doubled the amount of AN Bloom and added AN Big Bud but it doesnt seem to work, in fact the stems looks more red than ever.
