first time grower here. My plants are growing great. They are all auto flowering and auto feminized under a 300 watt led full spectrum light . They are in 10 gallon pots with worm casting, coconut husks and organic potting soil. I have recently been feeding them Alaskan fish nutrients ( the coloring happened before the fertz) and the ph is at 5.5 . Two of my plants look great but as you can see bellow one is a little light green with some light color splotching. I attached pics of my good plant and my plant that's splotchy. Why would it look like this?

The bottom picture is the splotchy one of you can't tell by the pictures

in soil you want your Ph to be between 6-6.5 5.5 is more for soiless or hydro ranges. the issue you are starting to see is Ph related to certain nutrients not getting taken up in your rootzone.

What is the safest way to bring up my ph I use my tap water which is from a well and it's oh is super low

Get you some Ph UP from your local grow shop/garden center. Or order some online.
