Looks droopy. You’ve got a load of vegetative growth. Like a damn jungle. I’d water a bit less. Run a risk and see how long it takes to start flagging (leaves waving in the wind due to lack of turgor pressure). Then water 12 hours before that happens. Once your flowering there will be more need for water. But I think you may be watering too much. You want the leaves to be raised to the sun. reaching for it.
I’m not a fan of
bud candy and super sizers and Gnarley Nuggets etc. theres always a new product but dudes have been raging the GH for decades and saved money and headache w/o those products.
anyone remember Humboldt bud hardener. good lord!!
just use the GH as Labeled for a dozen runs and you will begin to read the plants. “Little yellowing maybe add a 1/2tsp more of the green” etc. you will tune to the crop.
Adjust the pH of your Simple general hydro solution and let it grow. KISS.
edit. I see you are flowering.... your still looking droopy. Water a little less.
