hi, I cant see any cncering on your Grow atMoment. The only thing that disturbs alittle is the Big bloom... they have no need for it. In week 2 they looked a little "crispy" but now they are fine.... the spots you think its waterdrops=? ...Watch how the next nodes develop.. if they stretch to much lower the light, if they dwarf( very close nodes) rise the light... is it the Mars Hydro reflector 300?... if yes it has 120 True watts... and you maybe have to lower the light, but atm all looks fine
