Ok please help me here.....ok I'm on day 14 of my SH Deep Water Culture grow of white widow max. This is my first ever grow thanks for the inspiration Roseman. Lastnight I had drained and replenished my reservoir, roots are growing nicely into the water. So I flushed and noticed I had slime on air rocks and pump so I removed and cleaned so in the future so I could avoid PH problems and wiped down inside of tank with hot water used no chemicals! Added water and full dose of nutes in PH adjusted water 5.5. Next morning approximately 12 hours later plants are starting to wilt and curl up slightly some leaves just hanging down and doesn't have much support like it did yesterday. Also my plants had a nice deep dark green color now looking at leaves this morning there are spots on the leaves with light green so basically meaning my leaves are turning two different shades of green dark and light. I was very gentle on roots I feel I did not damage any roots. I did use cold water not room temp however this is my second flush and did the same thing the first flush and did not have this problem. Please any help would be great don't want to ruin my first grow
