Growing 3 Super Lemon Haze in 5 gallon fabric pots currently on week 6 of flower so a way to go and for the last 2-3 weeks my plants have turned completely yellow and the leaves are dying. The buds are green and frosty but I can’t figure out the issue. I’ve flushed twice tried upping nutrients and tried just giving water but the dying has progressed. What can I do? What’s the cause?
