Okay.
For the moment, forget that they are mother plants and think of them as vegging plants for simplicity's sake.
In veg, plants want at least 18 hours a day light.
They need a pH around 6.0 in rockwool, and a drip or flood schedule appropriate to their size, the ambient temps and humidity, and the light intensity. If you run CO2, that factors in as well.
They want a fertilizer that is high in nitrogen and has complete micronutrients. The strength you mix the fertilizer at depends how the plants react to it. Start on the low end and work up.
The water source may be tap water in some cases, but in hydro you are safer starting with distilled or RO water and adding calmag plus to it to simulate 'regular' water but cleaner and more predictable.
Check for bugs.
