Not really sure what my deffiency is. Havent strayed away from my norm. 3rd week of flowering. Growing in coco. Ppm 1.2ish. Ph 5.5-5 8. starting from bottom and moving its way up. was only visible in one now its working it way to several. The plant pic was yesterday and the leaf was off that same plant today. seems to be getting worse. Just did a flush.

Don't know about Growmore nutrients but by looking at some of their formulas such as the Hula bloom at 0-50-30 I wouldn't consider using them for my crops. Did you use a veg formula the first couple of weeks of flower or switch straight to bloom formula at flip?

i'am not familiar with those nutes, but the plant looks hungary, i would up the EC to 1.6 including your waters EC, i grow in coco too and i let my ph fluctuate between 5.8 6.8 if you dont vary the ph certain nutes will be locked out, PK gets locked out in high PH, MG, calcium get locked out in low ph , this can cause a domino effect locking other nutes out

Ratios aren't terrible but bobtokes may be right. Personally I've never had to run over 1.2ec in coir, but I don't change my formulas every week in growth or bloom phase. They get veg nutes' at 450-600 ppm from start to 2 weeks into flower, then flower nutes' from week 3-5 of flower at the same 450-600 ppm then tapered down from there.
