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...

Coco vs soil?
So next run I will be going with a coco organic roots medium vs fox farm ocean forest. I guess my question is what should I be doing differently? Ph? Run off? Temp? Perlite?

Molasses
Molasses when watering or no ? I know people use it for compost tea & flushing but I’ve been using it in my water (1 tbsp) for past few watering. Should I do this or just use it for flushing?

Wrong pH! What to do when watering with wrong pH?
Hi you all and TIA, yesterday I watered my girls but after a few hours one of them started to get her leaves down, so I checked pH on my reservoir and it was 7.9!! So my question is what to do now? Do I wait for a few days and then water again with right pH or should I do it now?
