Have already read your grow bible and started the plant care.not to much nitrogen or you shall only receive green leaves.When a farmer grows vegtables he wants quite a bit of fruit to grow as well as strong plants its all in the profit game.a Plant can ward of bugs in a way.Who watches the plants of the forest and looks for bugs.I use home made concoctions.Only organic fertilizer and 90% compost which I make.Later a word on compost tea. good luck planting Jeff
