2nd Grow Indoors

Topped for the first time, plants were getting tall. I probably topped a week too late, will have too much leg by the end of flower, wasted at least 7-10 days of veg. Regardless, plants look healthy and are growing fast now. They are big enough to lower the light again, 3ft from canopy now, still just 4 bulbs on. Mag deficiency still showing on the fan leave stems, but it’s common on a fast growing healthy garden. I keep adding cal mag but have not been able to get rid of the purple. As long as it’s not combined with other issues like dropping leaves, chicken claw or other issues, being somewhat short on mag is not uncommon
