I began using some Cal-Mag additive to the regular Masterblend nutrient mix and that seems to help. But I'm seeing some really surprising growth with this one particular light I'm using on some tomatoes. This light has some COB LEDs that put out a very bright white light, not much of the typical purplish light the other grow lights do. Grow lights have really come down in price, I guess since there are so many different manufacturers competing for biz.
I'm running out of lights (nine)....still have two to unbox and hang. And no more places to grow plants. I'm already running extension cords (heavy duty) from other rooms in this old double wide man-cave so I don't overload the breakers.
I reckon I just need to sit back and wait now. Maybe go shopping for some Blue Cheese salad dressing.
That's all I got....-!!!
