Time to Add Bloom Nutes

Hey friend, I think you're just starting to see her preflowers coming in, but regardless, still a sign that flowering is beginning. Most autos I've grown started between 4-6 weeks old. Since your leaves are a nice healthy bright green and you haven't been feeding anything yet, I'd say it's a good time to start bringing in the Bloom and Micro at a low dose, like 1/4 the recommended strength(something like 1/4 tsp per gallon) and me personally I've started to make a calmag supplement part of all my grows and seen much better results (but only maybe 1/2 tsp a gallon, once a week). Welcome back to the grow game. I hope the auto is fun to grow.✌️
