Strain Characteristic or Nutrient Deficiency? (Acapulco Gold)

Hello all,

boy and i are growing some barney's farm acapulco gold. a special sentimental strain for us. my brother in law passed from cancer 2yrs ago. last time we were able to visit with him (before he passed) was at the lake, in the boat. beautiful sunset, marley tunes on the speakers and a big fat spliff of acapulco gold he had a hand in growing. a memorable moment for us. trying to recreate the experience, and honor the memory. any practical advice for us is most welcome. first grow with this particular cultivar... so not entirely sure what the deal is with it. combed thru jorge cervante's, ed rosenthal's and ryan riley's books respectively trying to figure out what nutrient deficiency was causing this WEIRD discoloration on the leaves... and despite the weird discoloration, the plant is growing fast/hardy like nothing is wrong with it, and we are doing everything properly.
temps in normal range, humidity in normal range, soil ph, water ph, all in normal range. upped the nutrients that we thought were deficient. no changes in discoloration just more rapid/vigorous growth.

has anyone seen this before in their acapulco gold grows? is this normal or are we f*cking something up?
after trying everything to correct a nutrient deficiency, we just looked at each other and said "maybe this is the 'gold' of the acapulco gold name?" maybe it's supposed to look like this? you'll notice new growth and some old growth fan leaves down low are not discolored (yet?). weird.

i'm baffled. anyone have any insights with this?
pics with lights and without lights (for the haters)

ps: the sand on the pot surface was a last resort measure to destroy the fungus gnats that hitched a ride in on the bare root strawberries i got from home depot back in early spring. their invasion was brutal and absolute. they got into any and all inside plants that had been recently transplanted or started from seed.
sand + diatomaceous earth ended up being the winning combo. (the only good bug is a dead bug!)
the AG plants seemed to like the sand, so we left it be.

done.
appreciate the tip/insight. thank you.

some kind of tox. tips up, tips down, burnt tips, yellowing, browning/burning... :(
can see it all much better with the photos blown up.
gotta flush 'em.

adjust your feed regime also. You might be doing something wrong. Maybe mixing your nutes inaccurately, too much A not enough B something like that. Could be your bug damaged roots weren’t functioning at 100% and couldn’t uptake all the N,P or K your chucking at them. Your problem would’ve started before you noticed it, sometime around 2-3 weeks ago Im picking.

roger that.
thank you for your insights and assistance. (bug damaged roots seem quite plausible!)
most appreciated.

No they don't look like that because they're Acapulco Gold.

What soil are you using and what are you feeding.

Also, not to bring you down but Barneys Farm Acapulco Gold is not the real deal. It's a hybrid. I've grown it and it was good weed but it's definitely not authentic or like an actual 16 week sativa.

All I know is what I see. You need to figure out why now. pH? Root issues? Too much calcium or another nutrient?

not bashing you. i appreciate your thoughts on the matter. just letting you know it's something we considered and *tried* to treat it as such (without positive outcome).

agreed. need to figure out the why.
darkoh69 mentioned the possibility of the fungus gnats munching the roots, and the roots unable to handle the nutrients being thrown at it. seems plausible. the gnat invasion of '22 was brutal. they got into EVERYTHING.) was mostly using organic fish based nutrient solutions (5-1-1 and 0-10-10 respectively). i did add some worm castings to my soil mix (which certainly had a hand in attracting the gnats in the first place) and one spritz of super thrive for the roots when first transplanted as seedlings to this current pot.

your thought on calcium may bear some merit. i did add some powdered sundried eggshell to my soil mix... though i added the same to all my other photoperiod plants, and they are loving it. hmmm....

If you have fungus gnats I suggest something like peroxide poured through.

that was one of our considerations. but i gave it a 0-10-10 fertilizer a week ago and symptoms did not improve.

even IF that was a fix - leaves will not magically go back to normal - once leaves are damaged / necrotic they stay that way until removed or die off. That margin ( serrated edge ) damage looks like potassium def. You are locking it out. Even if you bump it you are just trying to stop progression. One bump feed will not show up front it needs time to get back to balance. And yes your nitro is kinda heavy - so that leaves it your feeding habits ( ppm / ec / etc )

- understood (now)

soil:
i mix my own soil for seedling transplant. measured by "scoops" of the hand trowel and/or teaspoons
- 10 parts raised bed soil
- 10 parts rough composted soil (lots of organic material (leaves, twigs, clumps of compost) - and yes i try to avoid the bark mulches... increases the acidity
- 6 parts peat moss
- 6 parts coco choir
- 6 - 10 parts perlite
- (normally also add 6 parts vermiculite, but there was none avail locally when i got my supplies - so increased the perlite content to compensate)
- 2 parts manure compost/humus
- 2 parts worm castings
- 1 teaspoon sun dried powdered eggshell
- 1 teaspoon sun dried powdered banana peel
- 2 teaspoons (white) wood ash

feeding:
- 1 spritz of superthrive when i transplanted the seedlings for root growth
- normally feeding 2x week with
5-1-1 alaskan fish fertilizer
and/or
0-10-10 alaskan fish fertilizer
- other than that just water. tap/hose

barneys:
not really bringing me down, it's what was available in that name where we got them. we'll get this grow under our belt and perhaps seek out the real deal at some point. thanks for the heads up though.

If you started with purchased bags of raised bed soil that could be an issue as some of it can be mostly wood and manure depending on brand. You're initial soil looks like it had plenty compost, manure, and EWC so you may have started feeding too soon. As far as the Alaska Fish fertilizer goes, I known people that have used nothing else for decades and they grow some very good weed. You need to be careful with it as you can easily burn your plants with it.

With the burnt tips on the new growth it's probably best to just give them plain water for awhile.

Good luck.
