DWC GDP x Solodial x Lemon

Light swapped to HPS. This week I have removed a lot of the yellow leaves. I have been changing the reservoir water every 3 days with fresh nutrient water try and diagnose what appears to be a copper deficiency or heat burn from the lights themselves which are as high as they can go at this point. All things point to PH being just a little bit higher than I thought from eyeing the tests colour. I have removed the Male and successfully spread out the female using rubber bands and LST training. Note: the rubber bands are annoying the heat makes them snap more easily and the plant has learnt to resist the rubber bands and pulls itself up every day. I’d estimate there is currently 15-20 viable branches that are thick enough to produce a good final product. I’m flowering them short due to height constraints in my grow room.
