This is basically the feed schedule I use, though Im using my fertilizer in Promix BX, and hand watering vs pumps ect.
This feeding schedule would be for an 8 weeks strain. I would slightly adjust for shorter, or longer flowering varieties.
The people that came up with both the Fertilizer, and Feed Schedule, have been making Plant Specific Fertilizers since the 1970s, and have been making Greenhouses, and Supplies since the 1960s. They also sell Organic Supplies, and Predatory Insects ect.
They came up with the formula by TISSUE ANALYSIS.
Theeir formula consists of??
Base Formula
4-20-39
15.5-0-0 Calcium Nitrate
Magnesium Sulfate ie- Epsom Salts.. These chemicals are also to be mixed in this order. 1 at a time. Thoroughly mixed.
Flowering Only in Weeks 2.5-Week 4
0-52-34-Monopotassium Phosphate
Starting from Seedling x Week 1 they are fed a small amount of all the base nutrients, and slowly increased over time all the way until week 6 of flowering. ALL BASE NUTRIENTS.
In week 2.5 after flip MKP is added along with ever slightly increases of base nutrients. This is kept up through 4.
Weeks 5-6 Epsom Salts is added to boost the Sulfur, and Magnesium. All Base nutrients also keep Slightly going up. Sulfur is really important at this point, as it is highly active is helping produce Terpenes.
In weeks 7-8 ALL nutrients are cut back 50%.
