Blackberry kush screen, active air flow.

Starting to show signs of some deficiency. Looked into it more, found I could water them more often due to them being potted in mostly coco coir. I flushed them with 5 liters each of pH adjusted water. Then a few hours later gave them 5 more liters each of nutrient solution with the bio boost at full strength. Bio Boost is mostly phosphorus. Dr repair is nitrogen in urea form, and a small bit of chelated iron. I will continue flushing and feeding like this for the next few weeks and see how it goes. The biggest plant has had problems since day one. But has always grown the fastest and stretched out more than the other 3. Feminized seeds and their odd phenotypes I guess. Genetics are weird. Very sweet smelling. My house is over taken by the smell when I open the tent. Carbon scrubber on exhaust works very well.
