Greetings to all I have a couple of plants that are growing very slowly. They are still small and Im using 135W LED lamps. I have given them some nutrients after waiting for 2 weeks and the plants are around 3 weeks old. I wonder, do they need ONLY blue light or should I mix blue with white and/or red light? Will attach a picture of the plants. What is wrong with my plants?? I need help cause Im soon going crazy...
nute burn too potup up to 3 usg pots mix in 30% perlite above all get a bigger light and yes use red and blue colors those 2 colors make correct distance on the internodes of the plant good luck
