I get that insufficient nute thing too even when I SEEM to be fertilizing enough, maybe a pH thing in my case but far from certain, could be insufficent uptake or God knows what! But your plants seem to be coming along fine. I had tried some peak strains along with other strains, but that crop was underperforming overall so can't blame any seed company or strain. Have plenty more peak seeds I want to try, so I wish you well
