This is happening on my blue mystic auto.

Pretty sure it's a K def. Should I iust flush or add more nutes next feed?

Current @ 1/2 reccomended dosage using flora trio

Ph always 6.3

My first guess is that even 1/2 strength nutes is burning.
If you're in hydro what are pH and ppm500?
 
Nute burn and K def are often confused. What makes you lean toward nute burn? Also I'm in soil

Any good fertilizer used correctly shouldn't produce any deficiencies, except possibly CalMag.
But I only do hydro.
 
That looks like K - potassium deficiency and since K can be locked out by to much calcium be careful with Cal-Mag additions. The plants look a little lime color so I think you can up your nutes in general and add a P-K booster. Keep RH >40%<60%.
 
I've been using liquid kool bloom at 1/2 strength. Maybe I should lay off the cal mag then. Or is it too late.. should I do a flush and start back with 1/2 strength ?
 
which KoolBloom, liquid 0 -10-10 or the fierce dry stuff? Here's the problem: K toxicity and defc. look very similar, burned tips and margin teeth tips,... typical nute burn browns ouit more evely along the tips.margins, but teeth browning is very tell-tale for K issues... So your total K inputs need to be assessed,....
 
I am using the liquid kool bloom, but only at half strength.
