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 .

The clone has bad leaves. Need help Tell me, friends, what's wrong with my clone, I still can't figure out what's missing or too much. When I gave him just water PSH 6, ppm 10-15, he turned yellow. When I added water with a minimum amount of fertilizer for 1 week for vegetation, it also turned yellow.
