Hey guys,
so i started my current NFT grow about 2 weeks ago. It is my first Hydro grow, i was using rockwool for about 3 years before.
I started my seeds in coco cubes and transfered them into the nft system after a week.
The roots werent long at all so I raised the water level so all of the cube is fully submerged in water. It is more like some kind of RDWC now.
Now I got signs of overwatering. Really slow growth. I thought that would not be possible in hydroponics? The plants are turning yellow from the top and are hanging down.
PH is stable 5.8 and water temperature is 20 degrees celsius. I use a small airstone in my reservoir but maybe it is not enough?
Is it bad to fully submerge the rockwool/coco cube in the water (maybe some DWC guys can help me out here)?
