CDLC Coco DTW Grow First Indoor Grow

Ran into what looked like a K deficiency, with some spotting and tip curling on fan leaves. EC was coming in too high so decided to flush out with a bit of Florakleen. Not seeing any more progress on that anymore. Was confusing also because some of the fan leaves are getting a purple fade. Trichomes are getting cloudier, noticed a few amber but only on top of buds so calculating at least another couple of weeks. Unfortunately the frostiest of the two girls is not filling as much as the other. But both have a beautiful purple hue in the buds.
