As I am growing automatic plants arriving in the 5th week it goes into pre-flowering and I was thinking that my 140w led panel would not suit me in the 3 foot cover of the grow. So I invested in a new 240w panel that will provide me with excellent coverage. This week I added the koolbloom to meet the needs of the plant in this phase of transition to flowering. The first pre-flowers started to appear and the plants showed good vigor. Some brown spots on B2 show some magnesium deficiency, decreasing the watering interval and increasing the callMag a little.
