Aliendog (Ether Pheno)
Veg time: About 1 1/2 months

Lighting: 2ft 4bulb T5HO
Temps / Hum: 65-80F 30-50% RH
Container: 6 Inch Square Pot
Nutrients: General Organics BioMarine / CalMg+

Looks to me just like a Magnesium Def. Last watering PH'd Nutes going in at 6.4 Runoff at 6.6-6.7 This Problem is happening from the Top-Middle of the plant. I can't figure out the cause. I've tried PH Flush / Foliar feeding CalMg+ / Upping the nutes. I have experience slight tip burn from upping the nutes.

Any Ideas?

Could it be a rootbound problem?

Anytime Chemdog D is involved as in this cross I hit it with cal/mag everytime I water until it goes away. Chemdog is a nute hog but even more so a cal/mag hog.

Your runoff ph is a perfect level for Calcium absorption so it isn't that. I think it just wants more.

You could also mix 1/4 teaspoon epsom salts in a quart spray bottle and foliar feed it for a quick boost in between watering. It seems to have some tip burn so you could back off on the NPK a bit while you give it cal/mag therapy.

Don't flower it until it is green and happy looking. It will only get worse.
