I gave them their last feeding today. They looked a bit hungry but the end is near. After this they only get reverse osmosis water. 15 plants need a LOT of light and produce a LOT of big assed GORILLABUDS! The next grow will not be on this scale at all. I had forgotten how much space this many plants takes up. Starting out with 8 plants and ending up with a lesser number would be better for me. Maybe I'll do a Blueberry grow journal next time or Northern Lights. This was a lot of fun and the information on this site has helped a lot with the re-learning curve. Thanks 420times for bringing so much information together and making it freely available to growers everywhere.
