What's next for this plant? Am I ready for nutrients? Daily watering?

Hello Rollitup community. I have a sativa hybrid (from PurpleCityGenetics) that is potted in a fabric grow bag with Miracle-Gro soil, and the rockwool cube remains. The plant is doing fairly well (pictures attached). I'm curious about the next steps. Which nutrients should I be giving it and how often? Should I be giving it a little water each day or a big soak every few days? Your suggestions are welcome.

Unfortunately that soil is not a great choice, don't get me wrong, it will work, but it already has time release nutes in it, so for 3 months it's a balancing act if you add additional nutes, because you don't know what is released (NPK) when, and at what rate. As far as watering, don't water every day. When you do water, thoroughly water around the outside edge of the pot, and work your way in towards the center with a lesser amount, you want to force the roots to search for water and expand towards the edges of the pot. Once thoroughly watered, allow the soil to become pretty dry, almost to the point of the plant drooping a bit. When the pot is dry, pick it up and note the weight, then water and again pick up the pot and note the weight (in your mind, although some actually weight their pots). This will give you a decent idea of when the plants need water. Also, don't get a moisture meter unless you go real high end, like BlueLab. The cheap two prong Moisture/PH meters on Amazon are notoriously innacurate. Hope this helps.

Phytoplankton is right, but growing in soil is O.K. for me. Water her every 2-3 days throughly depending on your conditions (temps., humidity) and put sume nitrogen in every or every other watering until she starts flowering. Then switch to less N and more K nutrients and slightly less water. Keep her healthy until harvest.

Still some time to veg. growth, I´d be thinking of bigger pot in about 2-3 weeks.

If you don’t water the entire pot the roots have no reason to search for food/water
The larger the root base the bigger the plant
Water it
It’s big enough it won’t drown
It also looks like you recently transplanted so that soil should have plenty of nutrients already
Water it

That crap looks like a bag of pine mulch

Unfortunately I don’t think you’re going to get much out of that. The soil will keep feeding nitrogen when it needs other things, and it’s already pretty late in the game now to get much more growth with that soil.

Don't ever use anything that has slow release fertilizers , anything miracle gro, is never good..
