Hey ppl I'm in week 7 of flower buds a looking good and heavy. But I just opened my tent an noticed there's been a few white flys in there I'm wondering if its possible still to use neem oil while its at late stages with the buds being present. Also some of the leafs are turning yellow is this normal? I'm jousting 8liter bottled water and using bloombastic 8ml fo the 8 liters, 400watt sodium light on 12/12 any ur replying ill be grateful
