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...

Adición de Blackstrap Molasses al programa outdoor/soil Biobizz- Try Pack (Fish/Bloom/Top Max). Cual es vuestra opinión?
Is it harmful to mix blackstrap molasses into the Try Pack base Soil/Outdoor-Fish/Bloom/Max program? In what amount (liter/little spoon)? When should I use it? I don't think over-fertilization will happen, but will it be beneficial? I just stopped using Bionova after 4 weeks of Autoflower Supermix and before PK13/14.

Dry and Liquid Organic Fertilizers
Hello fellow growers I have been curious if anyone has used both liquid and dry fertilizer in their grow? I am growing in Coco and using a super coco mix with top dress and tea with dry fertilizer. If I add liquid fertilizer would this kill the living microbes in the coco?

Does low ph runoff need attention?
The ph run off of my plants has been consistently low, ranging from 5.5 to 6.0. Should I be concerned? The soil is Fox Farms Ocean Forest. The plants are OG Kush and Gorilla Zkittlez Autoflower. I’m feeding them straight tap water with a ph of 7.5-8.0.
