I3LUEYEDEVILstarted grow question 6y ago

A few days to flower...some lower fan leaves have yellowed and I removed them. How do I ascertain whether an off pH, heat stress , or nutrient issue is the cause. What is my best course of measure to correct this issue?

Ph your water when you feed helps and a nutrient wand to make sure you know the ec of the water your feeding. Yellow leafs at the bottom probably isn’t too much of a worry they die off from lack of light in the flower stage normally .

I may have over watered or it could be nutrient lockout. I only feed them every 10days to 2wks. I was switching them over from 1 fert to bloom fert by mixing 1 tsp of ea into 1 gal water but I did it 2x in a row. BEST WAY TO FIX THIS ???

Defoliate yellow leaves?Should we remove these large yellow crusty leaves near the soil? The plants are at about day 38. I've heard people say you shouldn't defoliate this early in flower. Should I be concerned about these leaves dying off or is this normal?
