Hi, its a big market with Nutrients, and getting bigger. Ihave no idea how your nutrients work . But i have on e rule, look for the companies recommondations and take half of it... that fits in mostly every case. And yes thats the way you do it in growing, Start slowly.. look how your girls respond . Look for the recommondations of the fertiliser company, follow them , but take less of the stuff. until you see whats happens. The effect of a fertilisation you see up to one week later....So its alittle tricky. But less is more is the best rule if it goes to Fertilising and watering. A defiency does not harm anyone, the plant can stand this for weeks. But an excess makes the plant sick// kills it.
One more. If you fertilise, just do it into humid// hydrated medium. So just give your plants water, then the feeding solution. So you are sure the solution spreads everywhere in the pot and does not concentrate in one point.
I do it like this i give my plants water with beneficals like molasses and humic acid, then i mix asmall batch of feeding solution and feed them after that watering ( 30 mins later)
