A question from a fellow grower:
I have a few plants and new’m under house growing but do not know how serious this is? I’m watching all the aspects that I read in your book, the quality of land for crop, good light (600w HPS), CO2 (bags), regular transplant, carefully watering (every 2-3 days), from fertilizers put 1 week liquid organic fertilizer and HESI some drops - amino acids. I use the water we drink, and because a lot of quality and pH around 7, a small problem is that the room (improvisation) still quite warm (around 30 °) because of that light, I have only a home fan and running the entire 18 hours with light I know that I do not have adequate ventilation or have to make sure that someone does not see or feel that room, moisture keep him around 50-75% so I’m not sure what it could be other than that I might be a little bit less watering? The problem that worries me is that it appeared slightly yellow edge on the leaves of some plants … I attached a few pictures, the first two are Northern Light fem. the other two are White Widow fem. These are plants that are 20 days in growth and are otherwise quite healthy except those yellow edges, I hope that we will find an explanation …? Thanks and regards, later.
