Outdoors early morning or late evening because you do not want water drops to act as magnifiers for the strong sunlight. It can burn the plants. Indoors it is best to just dim your lights and mist so the plants are dry before night.
I went ahead and bought the GL Kelp on Amazon. I already have the best humic acid on the market, way better than RAW. YEARS worth at the tiny rate I use in every watering.
I think when I start my next grow, I'll do the foliar feed with the combo to flower and then in flower, use it with my regular feed schedule when I add either aminos or J.
