So Finally after after a lot of problems i think i got it right. First 3, 4 and 5 are ahead in growth and they drink more. At least 80 ml a day and if i feel they've been drinking more i just give more. Other plants goes between 40 ml to 60 ml but i follow the same rule. If smart pot is dry in the bottom i just given them more. I check the smart pots and if the end feels somewhat dry i make them drink until it is at least wet to the touch but without runoff. 3, 4 and 5 were definitely root bound. 3 was so root bound the roots were starting to become air pruned on the pot side. After changing and giving them more cal mag they seems to have started growing again just fine. I'm still dumbfounded how that don't lead to a Ca excess but well the plants seems fine. I may have to consider diminishing the Ca bit as the PH of the solution goes up since Ca becomes more available.
