  1. Would anyone have an idea of how Long I should be adding Cal mag to my reservoir drip to waste system using Coco. First week of flower? Or continue throughout grow? Thanks for advice

  6. I use RO and about 100ppm of Calmag in straight coco, until the plants tell me they don’t need it anymore. Basically, once they start to get too dark green I cut it out. Around the 2nd week of flower for me. Then I only use it if I’m addressing a deficiency later in flower.

    Probably the most important factor in determining its necessity would be your water source. City tap, ro, well? What’s your source waters ppm/ph? Impossible to give a solid answer without knowing that

  8. All great answers here. I don’t use calmag because my base nutrient comes complete so I believe ones base nutrient composition is also something to consider.

  10. I’m using Remo this run so it may work out differently. However, last run with Dutch Master Gold A+B I cut it out after the stretch without issues. This was what they looked like when I flipped them.

  11. And then around the end of week 3. About a week after stopping calmag.

    Definitely lush green. Nice. Remo hey? You using the recommended dosing? I found remo mixed up weak even at full strength, maxed out at about 800ppm(1.6ec) even w all the additives. I didn’t like the npk ratio of remo for coco. Too much potassium for coco imo definitely was formulated for peat based mediums. Coco has a lot of potassium naturally occurring. Check out @nMEEKS contributions on here man I think you’ll like the knowledge he’s dropped.....

  13. Thanks, I’ll check him out. I agree with what you’re saying about the ppms. But I don’t feed much above an EC of 2.0 even in flower. Right now I’m feeding 1.4 EC with Remo M+G, silicate, calmag, Bio-Cozyme. I flipped to flower this week, so I’ll see what I end up with swapping in the bloom and Astro flower. I’ll see how I’d does and maybe change up again next run. Looking at veg+bloom dry mix as a possibility. So far I’ve ran FoxFarms, Advanced Nutrients Sensi line, and Dutch Master Gold line.
