can't pin down the issue

You really should fill out the trouble shooting form. What is "ph water"? Do you mean Reverse Osmosis? RO does remove all minerals and you might be causing a deficiency of mag, I know I did and it looked similar. But if you mean ph stabilized regular water, then there is a different issue, not a mag def, which the plants really do not need a lot of.

So, fill out the form so the smart dudes can help ya more than I!

100% what she said.........FILL OUT THE FORM.........no more nutes until you get more info...you may be over feeding
