Emerald Triangle Magnum Gallon

- The primary symptom of Magnesium or Sulfur deficiency is premature yellowing or interveinal fading of leaves. - The most common cause of Magnesium deficiency is the high Potassium levels of bloom boosters. Growers use a high PK boost for maximum flower development so a Magnesium deficiency is always a potential threat. - If you are using Deep Breath to increase CO2 uptake, or you are using CO2 enrichment, the accelerated growth rate you expect to see will not happen if you have a Magnesium deficiency. Plants grown under normal CO2 will be even more impaired. - A lot of Cal-Mags are loaded with nitrogen (check the label) so you’re adding a “grow” nutrient right in the middle of bloom!
