Hey man, First of all lets get the basics sorted. Get that ph upto 5.8 to start with my friend. PH is crucial in our dwc systems. Right the next thing is. You have over fed and I can tell you how. Unless you fully empty the reservoir when growing in normal dwc every 2 weeks what happens is the left over feed from last time you fed the plants is upsetting your fresh feed. This is only my guess though to be sure after you feed check the ph of the pot and see if its over what you put it at. this will also cause ph fluctuations. Though do not worry my friend its nothing one week of flushing cannot fix :) Just put her on 5.8 ph water for anywhere between 3-7 days and you should clear her up :) then pump the nutes back in carefully if you are running an RDWC system then I would just flush then re feed at a lower ec. Amazing looking plant though man I currently have this pheno in veg so I'll keep eye on this diary ๐
