Lock out or lack of nutrients ?

Cannabis_carlitosstarted grow question 3y ago

I am having trouble identifying if this is a lockout or lack of nutrients. I was told to stop flora micro. I have been giving 50% strength of what the bottle suggests. My other plant same tent just had a lockout and I flushed.

1st time grower - nute burn? Lockout? Potassium def? Light burn? HELP PLEASE Experiencing some deficiencies/light burn/heat stress. Says SSH likes hot/moist climate. Plants are planted in FFOF Soil, fed them 15oz of nutes yesterday. Using advanced nutrient systems, see above. Light is a SF1000 LED meant for a 2x2 tent. Would that burn them hanging at 20”?

Why do leaves turn yellow and die Does this look like underwatering, heat stress, or any kind of defficiency? Also might be rootbound, cause I used not a lot of soil which also makes water evaporate faster. I water 0,8L/2 days pH=6.3=runoff, If its hot some leaves start to droop in less than 48h after watering.

Upper leaves turning yellow - Day 28 of flowering - Cinderella Jack Auto Only "half" of the plant is doing that. I don't think its a pH problem, the other plants are receiving the same source/quantity of water/nutes. My guess is the buds that are receiving more light are "maturing" quickly and the plant is sucking the leaves close to them. Thoughts?
