KingJayTkstarted grow question 4 years ago
Hey everyone,
I need help diagnosing this deficiency. I think its P+K deficiency. The lower leaves turning yellow then brown and crispy. The upper leaves edges are turning brown and the tips are curling upwards.

Hey there. I would put money on it being 3 things. Cal mag. Light stress. Or heat stress. Looks like or was a good grow anyway.

Hola. Creo que tengo el mismo problema finalizando la 4ta semana de floracion. Estoy un poco asustado porque la quema no para. Tu solucionaste este tema?
También pienso que se debe a una deficiencia de P.K. pero no estoy seguro!

Excess of Boron. (Maybe)
Phosphorous deficiency.
Potassium deficiency.
Temperature stress, overwatering (Maybe heat with overwatering, or or root zone problems)

Upper leaves are yellow and not smoothI noticed leaves on top are closing and today are yellowish. Older plant aren’t stretching more, I thought it’s too much light or too hot but it’s kinda weird because light are at 40cm from longer plant and 50 from smaller, temperature are max 26C. So, it’s normal?9 months ago
