@ImagiNathan Hi there! If there are no other symptoms then this is probably strain related. However if you noticed a slow growth or fading leaves, then this might be a magnesium deficiency. In this scenario, adding some cal-mag or epsom salt will help, plants should recover in a couple of days and stems will be green again. Hope this helps, happy growing!
@Stick,
She’s not slowing too much, and gets Calimagic with every watering since I’m using RO water. Next feed I’m using dechlorinated tap water to get my ph up with these Earth Grow nutes, would I still need to supplement the mag or does tap usually contain enough? (I know it’s different all over, just on average :D)
