Last week I started the feeding regimen and all far so good until I noticed some purpling on the stems and under leaves. Logically I suspected P deficiency, but was doubting it because I just started feeding with Biobizz's Bioheaven and Fishmix. But after taking a look at the bottles I noticed both of there NPK ratios were 0 for P. My bad hahaha. But since I alternate waterings with fertilisers, I had to wait to switch back to Biogrow instead of Fishmix. After a few days passed, brown spots started popping at the edge of the leaves and her growth was slower, confirming the P deficiency. Today I fed her with Biogrow, Bioheaven and Alga-a-mic and I expect to see her better the next few days. Also, LST starts this week.
