Deficiency, lockout or nute burn?

[sweetstickyfarms]

Whats good people, new to the forum and looking for some peoples opinions.

Is this... a deficiency, a lockout or nutrient burn?

Only odd couple leafs affected.

Currently week 3 veg.
30l fabric pots - feed every 3-4 days 20% run off.
Lights - Hps/led mixed room.
lights on temps - 25c-27c.
Lights off temps - 20c-22c.
RH - 55%-65%.
Media - ecothrive coco/perlite 70/30.
Nutrients - shogun coco a+b 2ml/l, katana roots, zenzym, silicon, calmag.

Additives are at half the recommended dilution rate on the feed chart.

Input PH 5.8
Run off PH 6.1
Input EC 1.2-1.4
Run off EC 1.4-1.6

Symptoms have only just started after last feed, re-potted from 5l fabric pots in to 30l fed a half strength feed and looked fine for around 4 days.

Fed them again and Put the feed back to what i was doing before re-potting, (stated above). Since then have noticed couple leaf tips yellowing and some slight yellow patches on some leafs with some tiny rust spots.

Any opinions and info are welcome.
Thanks. Ssf

These small yellow dots looks similar to mites if you got a microscope look under the leaf to see if there small bugs crawling there

The under side of the leaf looks fine, the purpling stops at where the stem joins the leaf. Will upload some pics of the under side ASAP. And temps are stated above. 25-27c lights on and 20-22c lights off. Thanks for your reply.

Deffo not mites dude. I always check for pests etc and already done prevention early in veg. Only started to show after last feed, which is why I'm leaning more towards deficiency, lockout or nute burn only odd couple leafs are affected

I cant say for sure just guessing not a pro
