I did it the same way, I even had a garden with 12 plants where I all try different tactiques on like lollipop, fim, topping and I fucked up my whole harvest.
Butt hey, I learned a lot from it.
The giving water u only can get in the fingers by looking at ure baby's & at the weight of ure pot.
Also with a good tensiometer, with the nutes ure better giving less then to much.
I grow with nutes from canna & Atami and I never use it on full strength, still when I come into flowers stage I keep overfeeding them a little, maybe because I have no ec meter :smokebuds:
