Bloom additives Full Tilt Alternative?

Why would you want to use those additives? Your plant look very healthy and strong already and adding those additives will most likely cause toxicities! Stick with your base and bloom NPK fertilizers throughout the whole grow and only use those kind of additives when you desperately need a quick fix to a deficiency. Try decreasing the distance between lamp and plants by about 5-10cm but other than that keep doing what you're doing, plants look beautiful!! Good luck and happy growing :)
