I used FoxFarms Grow Big and Big Bloom on my first couple of grows. Ive found that a little bit of the Grow Big goes a long way with autos. I recently switched to Sensi Grow and Sensi Bloom, mainly because they are pH perfect....and I was SOOOO tired of pH'ing 2-4 different feed bottles(plants at different stages). I am now learning to grow in Royal Gold Tupur(coco, perlite, aged forest product)....well currently on my 3 and 4th cycle with it. I LOVE this stuff! Anyways, I was/am having difficulty learning to start seeds in it. I had some seedlings that were very light....so I decided to switch back to FoxFarm Grow Big for a few feeds to see if she darkens up. I put 1.25ml of Grow Big in a gallon...for seedlings. A tablespoon is 15mL...so I think that is a little heavy of feeding. My Sensi Grow(Part A & Part B) says to use 4ml per L(3.75L in a gallon). I am using 4.5mL/gallon on the plant in my signature....the most I get up to in flower, is 8mL/gallon of Sensi Bloom Part A and Part B.
