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 .
