Just wondering what you think? Few fan leave going bad and tips on sugar leaves. I thought I was burning them. So last few waterings have been just water. Sorry for bad lighting. If need can get better pics.
Nut burn or potassium deficiency?

Lots more info needed in order to give any answer.
Growing medium?
Ph?
Pics without blurple light?
Pics without blurple light?
How much light / distance?
What were you feeding?
How much were you feeding?
definitely looks like a potassium deficiency to me, then again I’m no pro

Yeah I sorry about light. Foxfarm ocean forest. Always try water at 6.0 to 6.5. Run off at 6.2 if that really matters. Been using foxfarm trio. Following their recommendation chart. I use ro with cal mag too. 400w mg with 300w purple led. About 15" of so for mh and led is little lower around 12". Like I said I was seeing tips burnt like, so I thouht I was feeding to much. So been just plain water for last 3 waterings.

Runoff ph doesn’t really matter. soil buffers ph. Ditch the RO and use Tap as long as it’s not nasty well water.
do you have a PPM meter to check runoff?

Their recommended feeding is pretty hot. Most people use less.

That looks like a K def. can see how the outer edges go yellow then will appear burned.
Most likely antagonised by something else in your mix since you’re feeding high amounts already

THIEF ! …..
Nutrient antagonism is when an excess of a particular element blocks the absorption of another element the plant needs and can happen with elements of a similar size and charge (positive or negative).
Some of the most common antagonisms are iron blocking manganese (or the reverse), magnesium blocking calcium (or the reverse) and potassium blocking both magnesium and calcium and so on. Also elements can ” bind “ into a form that cannot be properly utilized by plant , thus leading to issues too.
Why less is more mantra makes sense instead of throwing every bottle in nute line at plant.

So theoretically the addition of calmag could possibly cause a K def / lockout? Is that what you’d say could be happening to @harbatures? Or am I reading it wrong

’ Yellow margins with tip burn ‘ …. Usually a K deficiency which at times mimics ” nute burn “ .
Since he is flowering - plant probably craving more.

The visible signs of potassium deficiency in cannabis are: The tips of leaves turning brown and looking slightly burnt.
