Yellowing Too Fast Or Natural?
I'm roughly 2-3 weeks into flower. Over the last week, I've noticed more yellow leaves than normal. Majority are bigger, older fan leaves but some are moving up the plants. New growths are a nice green and buds look healthy. Am I under feeding or overreacting?

Leaves yellowing and burning mid flower
Air exchange, pH, nutes, and water should be good. Could my 230 watt on 100% be too much for her? Does she need more humidity? What causes crispy leaves?

Calcium, lock out?
Hello, it looks like calcium, P, or K issues. Maybe pH lock out. I flushed last week and followed with nutes. Likely last nutes this week followed by a week or two of flushing before harvest. Please look at leaves and let me know what I should do as I end off this plant.

Nutrient Burn or Deficiency?
I recently fed her nutes and two days later I am seeing this yellowing on the baby sugar leaves on top buds only. Do I flush? Or is this a nutrient deficiency and not a nutrient burn?

Yellow leaves
The lower leaves turn yellow Is it due to a lack of nitrogen, or is it self-defoliation of the plant? (photos at week 5) I look forward to your advice) Should other leaves be defoliated or left as they are?

pH very low (5.0) but plants seem to appreciate it!!
The pH of the reservoir is lower than the perfect range (5.0) during flowering stage for almost 2 weeks but plants don't seem to suffer. They are growing very fast. Should I change it or leave it if they seem good?
