When to start feeding?
BlueDreamer1answered grow question 5y ago
I started feeding at this point as theres no nutrients in rockwool. Keep it a light feed. I didnt add cal mag so ended up with a deficiency. Make sure to add that. I'd keep it under 200ppm.

Organic dry amendment fertilizers and transplanting. When to amend?When using dry amendments, does the amendment schedule reset when you transplant with newly amended coco? I transplanted from 1g to 3g and the newly added 2g of coco was amended with the proper ratio of amendments. Do I only amend for the missing 1g from the "old" coco?Week 6

Am I Doing Enough at This Point? Newbie here...After taking a look at several other similar grows, I am beginning to wonder if 1) I am holding back on giving enough nutes, or 2) light is sufficient or overkill?

More soak for more runoff for bigger pots?I'm watering with 2l of RO/nutes every 48-72 hours, depending on moisture of soil. Estimate about 10-15% of this is runoff. I notice vigorous growth almost immediately after watering but then little more until after the next feed. Is this normal or should I be soaking heavier?Week 8
