I'm using Sunshine Pro mix #4 Sun Gro Horticulture | Products | | Mix # 4 Aggregate / LA 4

I always use 1/2 of what the direction call for when it comes to fertilizer....you avoid burns and lockout this way

I use greenleaves ferilizers with a built in PH monitor Hydroponics, Indoor Gardening Supplies, Hydroponic Systems - home @ a rate of 1 cap full per gallon of water.

Directions call for 1 oz per gallon.... I'm adding a 1/3 - 1/2 a oz per gallon....I use the grow juice once a week in veg... the bloom juice everytime I water in flower
