gh maxi powder series. ill get the npk when the lights are on. boy i sure hope you can help with DWC its my first time and i dont really know anything about it. the guy who sold me the system said he would help but he freaked or something cause he quit selling systems so im kinda on a limb.what you see in the DWC arw some clones i had in 3" rockwool cubes. i was planning on this rockwool batch so i just popped them in the basket with some rocks so i could veg them for the rw clones. when i started they were about 8 " tall. i must have given them too many nutes because they all froze and the fan leaves that were the size of my hand before i topped them ( needed clones ) were the size of a siver dollar coming in. i had no roots coming out the baskets and the last thing this guy told me was to go to 200ppm for a few then to 500ppm, so i did and nothing happened. thats when i lost touch with him. finally i got the guts to go up and did to 700. then 800 .nothing....so i emptied the res and just ran 200ppm. the plants picked up but then stopped. i slowly went up to 800 again. got some action. then stopped and now at 1100 for about 5 days and that is what you see in the DWC. id appreciate some tips...recipies suggestions to help me with this. im going to fwr whats shown ( need meds bad)and then start a new DWC only batch. i could sure use a mentor
