Are you feeding them anything?

 

[rocko369]

Yes, roots organics go box but I'm doing a test with golden tree so bio-grow and golden tree is my nute system for now!

So, not Roots Organic, correct? Not fully clear.

What kind of water? RO or distilled?
Are you adding any CalMag?

I'm seeing a deficiency in Magnesium.

Anyone else?

It's gotta be mag. More pics! And yes I'm feeding them.
Roots organics go box
Bio grow 10 ml gallon
Golden tree 1-2 ml gallon
No cal mag. I usually add cal mag but this run, I wanted to try something different!

I would think two grow nutrients would be a bit much.

High calcium, high pH, high potassium, could all probably cause a magnesium lockout. I think you're supplying enough,

I don't see any other symptoms. I think calcium toxicity just looks like magnesium deficiency, due to the lockout. High pH could start showing other deficiencies.

Check soil pH.

Hit it with a foliar of epsom salts, see if the damage stops expanding.

You'll probably end up flushing and feeding, regardless.
