I've had a couple of grows and haven't used a TDS meter, and I'm planning on adding that to my next grow.
I've read that seedlings (less than two weeks old) should have around 600 total ppm in their nutes. So I mixed up one gallon of seedling nutes from the GWE nute chart for coco. Here are the PPM's after each addition:
tap water: 281
after 1 t CalMag: 620
after 1/4 t Micro: 722
after 1/4 t Gro: 771
after 1/4 t Bloom: 790
CalMag had a huge effect on the ppm's.
Total ppm is 790. Should I dilute this down so the ppm's are around 600? Is 790 too high for seedlings? Thanks!
