Humboldts Secret Calcium, Magnesium & Iron - Liquid Nutrient/Fertilizer For The Vegetative & Flowering Stages of Plants (Quart)

This product did miracles for my bell peppers and tomatoes. They grew like wild fire and it reduced the number of bell peppers from getting rot spots significantly. I will buy it again.

I never had any idea how deprived my plants were untill I gave them some of this! There was a burst of growth I've never seen before! Calmag with iron allowed them to grow as fast as they wanted to,the leaves got bigger than I ever imagined they could, they smell very pungent too! This stuff is awesome! I'll never grow without it again!!!

Works well for introducing elements to raw coco fiber. Rinse non Soil Medium with this micronutrient to avoid uptake issues for cannabis. Note that it is 2-0-0 versus standard calmag of 1-0-0Use sparingly

I only buy this stuff, we get a good amount for a great price, I have never been let down by and neither have my plants

Size was great lasts long time but works quickly. Easy to usedursble seal was great promoted growth no smell
