Mephisto Ghost Toof Rockwool/selfwater

Hello I am continuing my efforts in growing I got a bunch of ghost toof seeds. I am using Dutch Nutrient, just some sample bottles the dude at the homegrown hydro store in toronto gave me with hand written instructions. I also have great white shark powder for here n there, I don't know how it mixes with hydro nuts. cousin gave me a bottle of Optic Foliar as a sample so I used it twice so far when I wasn't sure if the rockwool needed watering or not so I foliar sprayed it to wait one more day for the rockwool to dry before feeding. did that twice, and that's basically my plan of action here. I am using PH down from Dutch Nutrient aswell. first time using these guys so far no burns everything going well and third time total trying hydro in the most basic way. static self watering these rockwool grows until I decide or get good enough to add my pump and timer and eventually try to connect the system to my aquaponic tank. So far out of the 4 mephisto beans I've popped I think I've got them dialed in and this is my best go yet this ghost toof is growing very fast. Hope it stays this way as I was dialing in with soil the last two months and I kind of macgyvered the setup together after having great success last season with rockwool so I'm not sure if I'm dialed in to this self watering hydro thing yet but the whole thing just seems 1 level simpler and easier to do than organic soil growing. I'm going to continue doing this with rockwool until I fully dial in my organic soil runs with this seasons vegetable garden coming up. if anyone ever used Dutch Nutrient before let me know what your thoughts were on it. They sell an organic hydro formula too which im interested in, or wondering if I can self water with aquaponic water as well. organic hydro/aquaponic with rockwool has my greatest interest right now because I am pretty pissed off at my soil the last few months trying to fix little things. Lol Thanks
