Deficiency of something. Can't figure it out!

Hey guys I've looked everywhere and can't figure this out. Would be good to get some expert eyes on this to diagnose it correctly.
Week 5 of flower
House and Garden nutrients full line.
Ph 5.8 in coco perlite grow.
Yellow starts in the veins by the looks of it. But the rusty patches on the ends.
Appreciate the feedback.

check for root aphids you could be seeing phantom deficiencies

How do I go about that. Pretty sure I've no pests at

Thank you for your reply

Tuff to tell with bad info and lighting. This is a good book to have on file.

Looks like classic over feeding and/or salt build up.

Needs to flush it then with drip clean ill try that

check your roots? under the pot or if u have to take her out of the pot, same thing happened to me i had phantom deficiencies and by the time i checked there was a colony of them eating my roots away. now once i actually lifted the root ball out of the pot was a done deal the little fuckers colonized my entire root system

Looks nitrogen deficient to me. H&G has a separate nitrogen boost and the base doesnt have enough imo. You didnt add enough in veg and now your in mid flower chasing a nitrogen deficiency. Or zinc or sulfur but probably isnt sulfur as they usually get enough of that. need pic of whole plant. is this from the top or bottom of plant.

raise your ph to 6.1 in coco. take some full plant pics in regular light. it helps a lot to see where its starting, what it's effecting, tell us the temps, RH, what kind of lights.
