Hey just a quick question to do with nutes. Im a first time grower and have not used them before. Ive got 1x DieselxCritical Mass and 1 x CriticalxSkunk #1 Autoflowers in soil under 1x23w and 1 x20w 2700k CFLs. Pretty small grow, small space, small budget. My babies are in the the 2nd week of flowering. Bud are starting to form and a couple brown pistils 1. Is it too late to start using nutes now? 2. I know they need Phosphorus in flowering stage but is a NPK of 9-9-27 too much? I dont wanna burn the little critters.
