Miqgroanswered grow question 5 years ago Hey, are you using any nutes yet? If so... that may cause a little bit of tip burn at this early stage. I would only try half strength at this point.
If no nutes are being fed yet then it may just be slightly overwarered, try and get a proper wet-dry cycle going and only water when the top of the medium is fully dry. :) That will give you much healthier roots as they grow when in search of water.
Good luck!
