These plants havn't had the best start. I followed the house and garden feed chart but used roots gold instead of silver. Imonitored ph, temp, EC, humidity often, everything was good.?
everything you've mentioned sounds like a phosphorus deficiency (Purplish Or Reddish Leaves and Stem, and Stalled Growth). To fix this issue flush your system with clean, pH’d water that contains a regular dose of nutrients that includes phosphorus. This will remove any nutrient salts that may be affected the uptake of phosphorus and help restore pH to the proper levels.
