Heres my current growing media formula
Base Formula(baked at least a month):
45% Fox Farms Ocean Forest
15% Fox Farms Happy Frog
25% EWC
15% Perlite.
This will be my nutrient scheduling(qutoed from Shaded_One). For watering it will be as needed with 6.2PH water
Sprout phase, ~1 week: NO nutrients are being added to the growing medium. Earth worm castings & cotyledons provide more than enough nutrition for the first 2 weeks of a seeds life
-transplant to 1gallon-(will just use my base mix for this in conjunction with some Mycorrhizae)
Early veg phase, 4 weeks: amend 3tbsp of 100% All Purpose 4-4-4 per gallon of medium eg. 3tbsp of 4-4-4 for a 1gallon container
Late veg phase if needed, 4 weeks: top dress 3tbsp of 100% All Purpose 4-4-4 per gallon of medium eg. 3tbsp of 4-4-4 for a 1 gallon container
-transplant to 5gallon-
Early flower phase, 1 week before flipping lights: amend 3tbsp of 50% All Purpose 4-4-4 and 50% Power Bloom 2-8-4 per gallon of medium eg. 8tbsp of 4-4-4 and 8tbsp of 2-8-4 for a 5gallon container
Mid flower phase, week 3 or 4 of flower: top dress 3tbsp of 25% All Purpose 4-4-4 and 75% Power Bloom 2-8-4 per gallon of medium eg. 4tbsp of 4-4-4 and 12tbsp of 2-8-4 for a 5gallon container
Late flower phase, sativa plants: if you have a sativa plant chances are they may need an additional weeks of growing time so you could do a light top dress 2tbsp of 100% Power Bloom 2-8-4 per gallon of medium eg. 10tbsp of 100% Power Bloom 2-8-4 for a 5gallon container
-harvest-
This is the basic feed schedule and this is a FULL STRENGTH feeding regiment meaning you are pushing your plant pretty hard. Certain strains and different growing environments may mean that you might only need to use 2/3 of what I have here for amounts. I recommend starting off with 2/3 of what is listed and increasing to full amounts if you're certain that your plants can handle it.
Additional supplements that I use are:
Mycorrhizae
I generously dust the root ball EVERY time I transplant and I also add a couple scoops into my soil mix any time I amend some soil to be going into a new container. Do not underestimate your rhizosphere
Epsom Salts - Magnesium Sulfate
LEDs increase the demand for Mg and this helps cover that demand. Overall plant health and nutrient uptake seems to improve when adding 1tbsp of Epsom Salt every 2 weeks
Gypsum - Calcium Sulfate
Decreases soil salinity and improves soil structure while also providing Calcium and Sulfate. 1tbsp of Gypsum every 2 weeks
Basalt Rock Dust - micronutrients and humic acid
Used primarily to supplement micronutrients that may be lacking. Overall plant health and lushness improved since I started adding 2tbsp every 2 weeks
