Hi everyone-

I read before posting but I'm not sure what it is still. I know that some of you will see the pics and know immediately.

I have two separate veg kits in DWC. Two days ago the leaves in one veg kit (White Widow strain) were looking yellowish. The other kit (Northern Lights strain) was looking good, but there are purple stems on both.

I emptied the tanks and started nutes for the first time. BC Grow with BC Boost. Minimum PPM.

Now today, the White Widows look even yellower, and some have very yellow tips, and the NLs look pretty yellow with extremely yellowed tips.

Is this Magnesium? Sulfur? Too much? Too little?
