GMSgrowsanswered grow question 4 years ago If it's just a leaf here and there I wouldn't worry to much. Plantsmlook a good green so I wouldnt go higher on the nutes. If anything, if you haven't got a tds ph tester, I would recommend getting one. Check your runoff after plain watering, make sure your ph and ec are at the proper levels coming out your planter. This way your not guessing and it's easy to grow successfully. Cheers my friend
