So my seedlings were started around January 26th, and 1 is doing great, one has yellow leaves on the new leaves, and the third is not doing so well. I will attach a pic of it. I am thinking nute burn or heat. I have it in an organic soil mix, and under a 400w hps light, about a foot away from the tops of the plants. I have held my hand under the light above the tops and it doesn't get too hot. I water about once a week, when the soil starts to look really dry, and I am not going to be feeding since the soil should have plenty of nutes for the plant to thrive on. When I water I water with a mix of 1 ml of big time enzyme, and 3 ml of big time roots per gallon. I am not sure what is going on with my smallest plant so I hope someone here will be able to help!
Thank to in advanced for the help!
