Hey im kinda new to the hydroponic thing ive planted 6 medi bud/f in 30-10-10 soulution and its been two weeks since planting they looked fine for while but now 4 of the six have brown and yellow spots. I NEED SUM WORDS FROM THE WISE
That's exactly it....nutes too early. Run them on plain water for about a week, then you can add some nutes at 1/4 or 1/3 strength.
