Nutrients: I have a 400 gal. water tank that I want to fill with 100 gallons water to mix nutrients in.

The Brand of nutrients I have is General Hydroponics Flora: MICRO, GROW, & BLOOM

The Micro, it says, has to be mixed first. At a ratio of 2 Tablespoons per gallon water for

100 gal.

The Bloom is 1 Tablespoon per gal water, for the same 100 gallons.

The Grow is 3 Tablespoons per gal water, for the same 100 gallons.

With that ratio Ph was 5.9

PPM was 3300. I added 100 gallons more water , which brought my Ph to 6.1, and my PPM

to 2200. I mixed well and fed my plants.

My Plants are NOT happy!

What do I do?
