So I have these ten seedlings all of which are soon to be moved outdoors. My setup is 2 cfls, 35 watts about six inches above the plants. They're about two weeks old, I have moved five of them into a potting container with the other five being in red solo cups. The problem with the seedlings is that the majority of them have yellowing on the tips of the lower leaves and some have brown spots on the edges of the lower leaves or a bit towards the middle. Any tips or advice are greatly appreciated.
