So at this point you should be on transitional nutes. That's 10ml grow, 10 ml micro and 10 ml bloom per gallon. What I do at this stage is give them a total of 50ml grow, 50 ml micro, and 50 ml of grow. On the GH flora series you use all three to get a balance result and just lean heavy on N for grow and P and K for full flower. When you fill the tank as the plants suck up the water (expect around a gallon a day in full Flower) mix them up at least a medium batch of nutes Maybe something like 7 ml of each type, ph adjusted in a seperate jug ( I use a washed up gallon water jug from the RO I used to buy). Got to follow the bottle directions on a first grow. Experimentation is for later.
Before you do that I would want to know how big your plants are right now. You leaf problems are related to the lack of available nutes What the plants don't get in the water they rob from the leaf and you get all kinds of strange forms and colors. LOL!
