Is it more important to measure pH of soil or of the water/nutrients used for feeding? Or both? If so what’s the optimal pH? Thanks!

Is 1ml/L of food (I'm using Floramicro/bloom) enough feed throughout the growing phase ?
Is 1ml/L of food (I'm using Floramicro/bloom) enough feed throughout the growing phase ? I was advised that fastbud cream cookies don't like too much feed and that 1ml/L is enough however i don't know when I should up the dosage or if I need to at all.

Opinion - is Top Max (biobizz) worth it?
Hi all. I have the try pack (bio bloom, alg a mic and bio grow) and other two organic fertilizers (one has 16% P, along with calcium, mg and microelements. The other has 8% K). Do you think I'd also benefit from Top Max or what I have is enough? Anyone have experiencies with it?

EC and PH of Runoff still Higher than Solution even after a flush and lowering the EC
Hi, i still having this problem even after down the concentration of solution for 1/4 that scheduling feeding table says. I have some measurements listed in the week 10. Maybe my media is buffering PH and EC because i used to recycle it over times?
