I’ve been looking for recommendations for fertilizer for my outside grow. Last summer I used advanced nutrients Sensi grow/bloom with all their amendments. I had great results following their master feed schedule. My only issue was all the mixing. I’m looking for something that has quality results with a lot less mixing. Liquid or powder. This will be for my autos in 5gal pots and possibly a few of my photos in 10-15gal. I’m using ocean forest soil. Organic or synthetic .

Say a 56-70 day flowering strain.
Master Blend
4 18 38
Calcium Nitrate
Epsom Salts
Check Soil PH=5.8-6.2
Seedling EC = Day 1-14= .8
Day 14-?? Veg=1.6 EC
Early Flowering
Same as Veg 1.6 EC
Week 1-Day 20 of 12/12 ect.
Mid Bloom Day 21- Day 48
EC=1.8
Finish EC 1.6
Dont cut out any 1 nutrient. Raise EC by using all 3 products, or dilute with source water to lower EC.

Also mix in correct order
Master Blend
Epsom Salts
Calcium Nitrate

EC can also be higher than stated. I try and give a good feed, but not overdose, or try and force feed high EC, as than can cause hermi, yield and potency reductions.
