* Plants are about 21 days old from seed. about 6 inches high. Very bushy.
* Began to see these brown spots -- they look yellow in the pics but they look brown to the naked eye under good light
* I checked the underside for mites with 100X micro â?? no insects found
* I wonder whether I am over-feeding with the Nutrients because the soil mix website (which I just looked at) said there were enough nutes in the Soil for almost an entire grow cycle. i have been using the HESI nutes as directed from day one.
* Anything else this could be? Please help.

Ingoing water should be between 6.3 and 6.8 ph. Above or below that range, and different nutrients start getting locked-out.
Are you using a ph soil probe, or a ph pen? There is a major difference in accuracy. (soil probes suck)

Try looking online for the directions when in soil. (the link is below) If any questions, contact the company for clarification. I'm pretty sure you should be feeding once a week, not daily. Especially not twice daily. You are overdosing the crap out of 'em. Flush well and double-check your feeding schedule for soil. Mix what you can use on that day. You can't keep mixed nutrient solution for long periods. (overnight is ok, but 48 hours is too long)
