I'm not familiar with those nutrients but there should be mixing instructions on the bottles. For a seedling you would want to use it at reduced strength at first. Maybe 1/4 strength increasing the strength as the plant gets bigger.

Good luck.

1) do you have a TDS meter? Ppm. To measure the concentration of your solution. Buy one,
2) also buy a pH meter.

3) if not, usually the words on the bottle are too strong so, start at 1/4 and work your way up until bad things happen, then dial back a bit.

Read Snidley’s post and heed the advice. Organics in hydro don’t go well either.

Show us pics of the bottles. But I see that B says BLOOM so that’s for later. If A says ‘grow or veg’ that’s for now. Just use A.

You need meters that tell ph ppm/ec and water temp don’t go into hydro trying to guess you will fail every time organic is great for soil/ coco but for hydro you will receive small yields and low quality you aren’t creating an ecosystem like soil you are creating a controlled environment in hydro
