hey gc, my sprouts are about a week and a half old and the growth has slowed down. Ive got a small indoor setup with a 250w mh and a 90w LED set u with good ventilation and all that, and organic potting soil. My ph meter is whacked and i need more calibration solution before i can accuartley tell what the problem is. The soil has that spagnum peat moss which is acidic, and im thinking the organic time released nutes in the soil are burning my plants. I put a few gallons through each one and rinsed out alot of what i think was there. here are some pictures anyways any input would greatly help. These two photos sum up whats happening and they are both from the same plant. The first photo is one of the lower fan leaf tips burned yellow, and one is of the green-yellow spots on the leaf.
