I have a gallon of GH flora micro and a gal of flora bloom that are at least 3 years old. Been frozen solid and been in over 100° heat. I don't think these nutes are any good. I've had deficiency after deficiency and more nute lockout in flower. I think I'll be diluting this GH micro and bloom and spread it out on some ornamental shrubs outside. I wasn't able to store them in a cool dry dark place. No crystals formed but I'm thinking they are expired bc I've been having probs when I use them. Switched over to botanicare since I got 3 new quarts for veg, bloom, and soil. Got a Chocoloco 6 weeks in flower and she has a lot of leaves that look like magnesium deficiency.I I've flushed her and given her Cal-Mag, gave her fresh nutes, but I think I'm having issues with my old GH nutes. What does this yellowing and dying of the leaves look like to you? She's in happy frog all natural dirt. She can't be almost done flowering be I only switched to 12/12 six weeks ago.
