Don't feed anything until plants show first signs of going lighter in colour. If it's slow released nutrients I would probably start top dressing a couple of weeks earlier.My medium is miracle grow performance organics, and i have two 1000 watt led lights and my fertilizer 10,10,10
To be fair I know people who have done fine in Miracle Grow, not me personally I'm not capable of growing outside of hydro. So all you soil peeps have me beat.MIracle Grow is not soil. It's garbage and chemicals.
A lot of people use Fox Farms Happy Frog or Fox Farms Ocean Forest. I grow in Coco which is hydro and another world entirely.So what soil do you use
I mix my own medium up in a wheelbarrow. It is 40% black nursery soil, 15% worm castings, 25% moss peat, 20% Perlite, Then a bit of wood ash and rotted sheep poo mixed in. I used to grow in coco using flood and drain and it's convenient because the pots are light when dry. But I found that my yields are 30% bigger in soil.
