Third time but first with a dedicated cabinet grower

Although still in veg started this week with full range of nutes by mistake. I have added half the required from each to RJA and the exact amount for SC. I hope I won't burn them. SC3 got her plain water today. Will start LST with her later. I want her to grow a bit more than previous ones. Lowered the lights to above 30cm above plants. Hoping this to do good not bad. 1st day so far and no sign of light stress. D26 plain watered. Will implement further LST tomorrow maybe. D27 LST gone terribly wrong. One fan leave from SC and complete top from other SC. Fingers crossed.
