Deficiency but cant tell

[BenBernanke]

hey guys,

So woke up this morning and my plants have what looks like burnt tips. Zinc or potass deficiency?

And what could i do about it?

Specs:
RDWC hydroponics
Using 3 part nutes from general hydro
Using hydro guard, cal-mag, liquid karma, and sea weed extract
3rd day of flowering
Platiunum 300w lights x 2

Thanks a lot guys!

If you think it's burnt tips (i do as well) then overfeeding is usually your first guess not deficiency. Hard to tell because the pics are under led but if they are green and happy probably just a little tip burn back off the feed for a second.

Looks a lot like momentary heat stress
