Greenhouse Seeds / Sensi Seeds indoor grow

4-2, got some advice to lower the Led lights. I also bought dimmers, so from now I have 2 Sanlight Q3W gen2 Leds (120w each) on 60% at +/- 50cm above my seedlings. 6-2, the Hawaiian snow seedling grown out of the seed, first leafs are visible. Today I started with giving nutrients: Plagron Alga Grow (1ml/L) and Power Roots (1ml/L) together with the water. The soil is Plagron Promix with perlite, so I guess its time to start feeding the seedlings a little.
