I have 3 plants growing in an nft hydro kit under a 250w hps light. I have noticed weird variations in all of them that I have not seen before. I keep ph at a constant 6 and have recently just flushed them with ph altered springwater. 1 plant is showing deformed/ twisted new growth however the colour looks healthy. One other plant looks perfect and healthy and the final one is small, smaller but denser and stubbier leaves. I will put some pics up later. I have never had so much variation from plants especially as they are under the same conditions. Any thoughts would be appreciated. Thanks
