I am about a week into the flowering cycle of my first indoor project (see below pics). The larger one the left is the blueberry strain which I got from you guys in approximately may. I grew from the seed and it was going really well until 1.5 weeks ago when it starting turning yellow. I have been closely monitoring the PH, both going in and the run off and all seems ok. The medium is a course riverbed sand mixed with a good quality potting mix and I water it almost daily using quality Cannazym liquid. I have now switched to the Canna Boost for the flowering cycle. See some photos attached. Thanks and I would appreciate some feedback as to whether or not I should flush or just cut back on water and nutrients.
Look forward to your feedback.
