:point_up_2:t5: This guy gets me lol

Also!! PHing is important!!! Dont just drop approximately correct amount of calmag in some water then pour and expect results. U need that meter to make sure its right.

Sorry didnt talk about a meter. Get a pH meter. Apera 20 or Bluemats. The bluemats is a tad high but both will pay for themselves this grow

This is a medium range of the deficiency, I’m assuming that because the OP knows the ph, they are utilizing and correcting.

It also makes me suspect they are using RO or purified water.

Supplement calmag at 3ML per gallon every time if this is the case…

And also at op, why is it 6.2? Because you know the ph I’m assuming you have the resources to correct it…

Your water should be 6.5 after nutes.

I’d assume this is actually approaching late stage deficiency… based on the pics you have provided…

Here’s what the start of a calcium deficiency looks like…
