A mistake a lot of people make is thinking the more you add to a plant, the better off they'll be. You plants are healthy, leave them the f... alone. Don't add for the sake of adding. Molasses in small does is fine- it adds some Mg, a few other micro's and carbs to feed microrganisms in your soil. It's best used in flowering. Too much will attract bugs so go easy.
I'd only fertilize with water for a week, other then adding some epsom salts (and molasses if u wish). My best suggestion at this point is look into some zymes- Prozyme, Sensizyme, Hygrozyme, etc. These help break down roots, clean your grow medium and most importantly, breaks down fertilizer better so the roots can uptake them easier, faster and more efficiently. It stops salt build-up too.
Lastly, you don't want your plants to yellow up too quickly so go 50/50 grow/bloom ferts for a few weeks of flowering. Then going into week 3, go straight bloom ferts. THis is my formula and works for me but may not for others. I use Botanicare products in pro-mix. Ask 100 people and you'll get 100 different answers too. You're doing fine so far, don't stress over it. Let them do their thing and you'll have good success.......
