I have a few plants between 12 and 18 inches that are on their 6th day of 12/12 light (400watt Hortilux Eye HPS) in an ebb and flow table with rockwool cubes on top of rockwool croutons and sipping on GH FloraGro,Micro,Bloom in EQUAL proportions. My question: When should I change out my nutrient solution and adjust it to "Flowering" mode (more of the Bloom than the others) instead of the equal parts of FloraGro, FloraMicro, and FloraBloom? I've been following the GH's website's nutrient calculator and i'm currently on the "Transition" phase according to their nutrient calculator.
I switch to flowering nutrients when i switch to the flowering peroid. Just giving them a flush between grow and bloom nutes, maybe GH are different.
at this point, all you need is Micro and Bloom, 8ml of micro, and 16ml bloom per gallon, (lucas formula)
