Colored leaf

Hello my friend happy growing! Please give some info. Is she autoflowering or photo? Which strain? What lights and ph? Temperature and humidity?

hey there Mismey, think of the plant like a rocket launching into space, going slowly at first then shooting off, plants are the same, most of the action is actually happening below ground at this stage. the discoloration is probably due to pH fluctuation due to the root juice, cut it out for a few waterings, you should be watering with plain water twice then a feed, even with only root juice. that's the pace in soil, no to little run off. or pH your feed! Hope this helps ! 🚀

I would start with some low doses of bio grow, maybe 1/4 or 1/2 strength and slowly increase over the next few feedings.
