RDWC - Four plants in my system. 40 gallons total. I have a chiller, I use hydroguard and orca. FloraSeries Nutrients. Ppm 350 Water temp 65 Air temp 78 pH 5.7 Started as clones with large root balls , very healthy. Added to system 6 days ago. One is happy as a clam the rest are very droopy and curled leaves. They all have great root growth at this point and have just touched the water with one or several roots.
Seemed to be a nutrient issue I dumped everything and refilled with ppm425 everything been great for a few days now. Thank you!
