My 1st grow - 4 Auto RQS Greenhouse

5th week, Big grow and small trouble, I have some hole on some leaf and I have some soil fly. I have put some Citrus Essential oil, and I have return the soil to remove the fly larva and make the soil dry. Because of the rainy days, the soil stay wet. After return the earth I have found 2 larva I have throw away. And for the hole on the leaf I think that a start of aphids. I have put some oil solution on the leaf, and this remove all the aphids. I think this oil solution make the bottom leaves become a little brown, don't know why. The LST work well.
