Just had an advise from fellow grower to switch nutes to powder feeding - complex and had all the nutes in including micro. He had great results...
but only kali mist reacted with P overdose and threw purple stems, maybe you are right, but I never had this problem in early veg. Roots were so perfect, but I gave them Rhizotonic to promote it's growth. I was thinking in adding something similar to great white. Water chiller is too expensive...
Ukrainian style DWC:) - well, I did smelled the roots and no funky smell was detected. Roots are colored a little brown because of nitrozyme I use - it is brown as fuck;) - I will post pictures of my roots tomorrow.
I used to grow 8 600w lamps 9 plants per light crops in soil. Now I switched to coco/dwc hybrid
I use double buckets with coco and air pump inside. I have constant solution level 1 sm above the coco pot's bottom. I have control bucket with leverer connected to main water tank I put my nutes in...
