Hey guys

Here's a pic of one of the lower leaves on 1 of my plants and i was wondering if this is a Calcium/Mag Deficiency? I have 4 plants all the same strain growing in Pro Mix potting mix and there are 6 weeks old and i water at 6.3ph with tap water.

Thanks for the help.

Are you feeding them anything? Most promix doesnt have a whole lot of nutrients at all

I would not steer my grow based off one leaf. If the plant is ate up with those types of leaves, then you have something. If it's one, it would be best to be patient. Full plant pics under white light would be helpful. Good luck

I also run GH but you need cal/mag so I am sure you have a huge cal/mag deficiency. I don't know what you feeding and how high your tap is in EC but I am sure it is cal/mag
