Week 10 of Autoflower, how much fertilizer?

you are in full bloom, you should follow ADVNuts instructions and feed at 4 mL also and especially with Grow, if you use ADVNuts add B52 (vitamin B and potassium) you could flood the substrate and measure ec of the draining water so as to get an idea of ​​the amount of missing nutes i don't know coco grow well, but i think you have to load up the elements, coco is much poorer in nutrients compared to soil Thats my two cents Hope it help, good luck buddy! 🍀🍀

@Jannis_Botanicum to be honest she could do with more as you can see from the yellowish leaves if you let the deficiencies get too bad the plant will cannibalize itself resulting in less yield some extra potassium in week 6 should see you thru until the end Good luck mate
