This week, I just added nutrients as they are getting bigger. The nutrients I added were 1 tsp. or 5 ml. of Floralicious, Hydroguard, Calmagic, Floramicro, Floragro, & Florabloom. Theyโre almost in the veg stage so I went from 450 ppm to 800 ppm. Not a significant increase but just enough to keep them flourishing. I also topped each plant on day 14.
