Deficiency
KingJayTkstarted grow question 6y 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)

Leaves rippled ? What causes this?These are pics of day 13 seedlings. The larger leaves show signs of something but I don't know what. They are Blue Dream Autos in a 50/50 mix of Happy Frog and Ocean Forest. Temps have been 74 degrees F with 50% humidity the whole time. May be nothing but this is my first.

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?
