Hi guys, Currently in ending the 2nd week of flowering of a 6-7 week flowering cycle. I am growing in a soilless coco mix. I have a pump connected to a hose for hand watering. I have been using the following nutrients line, CCH2O - Current Culture Hydroponics - Cultured Solutions Currently using their Bloom A, Bloom B as base nutrients, Bud Booster as the flowering booster and UC Roots to block against high levels of build up. The question is the following. I was given 3 Bottles of Advanced Nutrients Flowering Phase additives, 1 Big Bud, 1 Bud Candy and 1 Nirvana. If I keep within my PPM range, is it safe to mix the two and would it be in any way beneficial to my plants. I don't see how I could really hurt them if my solution is in a safe PPM range but was just wondering if there are any nutrient mixes one should worry about that could cause potential harm. I am also wondering what other people would cap their flowering PPM at. I have slowly been building up to my current solution at 900, which would you guys consider to be a safe cap to the final weeks before flushing? Thanks!
