Gorilla Bomb Clones 2020 (IV-VII)

Day 84 for these four Gorilla Bomb clones. Two weeks of flowering complete, seven weeks to go. The green has progressed and is going dark. I’ve has this happen before and nuked my first two Gorilla Bomb plants. I thought those cases were nitrogen excess, I’m not sure how that could be so this time around considering how small the pots are, and I’ve been giving water. Hopefully its just needing phosphorous and potassium. I’ll try food out next as we have passed stretch. Hoping this is just colour and nothing too drastic approaching.
