@420SA I agree with the fact that there most likely was to much Nitrogen during flowering. That clawing is a sure sign! The Wonderblack I grew from Pachamama resembled @KlutcH's grow. The purple however might be due to lower evening temperatures. As about half of my plant started purpleing as temps started to drop at night.

@Za Weed Lover 2x2m I would want at least two 1000w hps or 630w cmh'sin there as a minimum. Personally I have switched to Quantum LED's for 1.2m areas in the following config: 3x Samsung LM301B 3000k and 3x Samsung LM301B 4000k driven by a Meanwell HLG-320H-2100C to 320w Supplementary Red Cree PCBs at 130w powered by a Meanwell ELG-150-C1050A This combination for a 1.2x1.2m, with up to 2.7 uMol/J efficiency if you running the Quantums on a dimmer. It can however be pricey to buy, if you can however source the parts yourself to build one or two it will work out cheaper in the long run than an HID. It will also help control the temperature in your grow room, as it does not put out close to the same amount of heat as an HID light. If you want me to point you towards where you can find components feel free to PM me.
