So my question is as follows:

Across the various basic phases of the plants life: seedling-veg-flower

How are you measuring your liquid nutrients under a ppm scale:

1) my RO is pH'd to 5.7-5.9 and has 40-45ppm
2)cal mag added to one gallon at 2.5ml adds about 200ppm, i then went back and diluted this so my aggregate ppm finished at 220-240
3) Soul GROW, Soul Grow-N, both contributed combined to an additional 100ppm over the 40-45ppm RO water for a total of 140-145ppm nutes and RO.
4)how much can I elevate a 150-200ppm nutes + RO with cal-mag? can I add 200mg of cal mag to young seedlings?

Any help is greatly appreciated. Am growing in Rots Organic Coco blend.

Veg tent is 8x4, orbital fan, 400 cfm fans on the fresh air intake and outage ducts, two 4x2 T5s with Agromax Veg bulbs, and a humidifier. Temps are steady at 74 - 75*ish 24/7 (should I drop my temps at night. On an 18/6 schedule now.


Thanks All

Never ph water before nutrients added
Babies 200 ppm
Teens 500 ppm
Adults 1000 ppm
This is rough scale
Adjust per strain and visual assessment

Thanks for the quick response. IS that 200ppm of calmag? also, is it a problem if i pH my water before and after adding cal mag and nutes? just to clarify.
