You can start feeding them,20-20-20 sounds right but use it only at 25% strength 🙏

Make sure the fertilizer has some form of other secondary macros and [micro nutrients]. Ca, S, Mg, [Fe,B,Zn] exct. Cannabis is a heavy feeder and loves extra calcium and magnesium Good Luck!

20-20-20 is a good start, give them a small dose at first and as they get bigger give them a bit more until they're getting a full 1 and half tablespoons...
