@Iwishiknew - Week 3 of flower is when I start small dosing P/K's and increasing strength every mix thru wk 7
(I use
MOAB 0-52-32, its hot!), Wks 4/5/6 will be her hungriest weeks (emphasis on wk 5) these are the weeks i use full dosages. she will be done stacking wks 6/7/8 (final fruit setting), after week 7 I drop way back on P/K, and I cut my Base Nutrients (grow/bloom), those final weeks 8/9/10+ she'll be fattening/ripening. I will keep dropping back on all nutrients until I am at Plain water by wk 9/10 (depending on varietals). In DWC I will run a 10-15% lighter on Nutrient Strength, I ran flood tables, rdwc, dwc for years, before I sold my Property, Im in a small condo now, and run perpetual grows in Coco, I dont care about yield too much anymore, topped once and I just let'em grow naturally(im always over my 2lb limit in house), I still run a couple simple bubble buckets in the winter months just to stay frosty! lol Cannabis loves the water!
There is a point where she will have all she needs to finish... and to keep pumping nutrients can be a detriment.
(
MOAB is good stuff we tested this product on 9 plant flood tables, same strain side by sides= it works!)
Your Plant looks good, keep them water temps in range, keep a daily eye on the pH, towards the end I like frequent wkly full water changes to keep pathogens from colonizing. (video, current wk 6/7 clones in tan pots/seed plants in white, retired old pot farmer grow-lol)
Keep at it!
