Sweet Seeds Auto Green Poison (and some Dinafem Auto Original Amnesia too!)

Hey guys I´m having a problem with one of my Amnesia´s and would love a bit of help!
Its day 44 and the cal mag issue that I was seeing has got much worse on this one girl.

She has been getting up to 3ml/L AN pH perfect Grow Micro & Bloom plus Big Bud and 2ml/l calmag.

Ph is bang on - everything goes in at 6.5 and run off varies from 6.4-6.6. Temps are a little high - up to 28ºC but its been hot recently! The affected leaves are also yellowing. Now I would usually expect some leaf loss at this stage so the yellowing may not be related.
Here are some pics

Do you think she is just a bit of a calmag whore and wants more, or is there something I´m missing? I´ll wait and see if anyone here can offer any advice, and if not I´ll post on the live help thread as she is due a water and feed and I would like to try and correct this if I can!

I'm no expert but if it's any help it looks like phosphorus deficiency.

Hey thanks for that mate. I´ve done plenty of googling and what is confusing me is that they have been fed consistently and even a little too much (a bit of tip burn) so they should have everything they need. PH is good so it shouldn´t be a lock out either. I´ll figure it out anyhow! Thanks for the help man!

Nice looking girls though, good luck.

Thanks man - I´m sure they will be fine. It may cost me a bit of yield but there are 8 more looking healthy so things could be worse!

It could be excessive evaporation around the leaf edges causing them to look "dry and fry" if that makes sense
What has your Potassium intake been like? Can you spot her a little molasses in water?
Hoping some ideas help friend
But I think you'll be back on track good growing dude,
I enjoy your sharing :Sharing One:

Hey redd, thanks for the words bro!
Potassium shouldn´t be a problem as far as I can tell because as well as the 3 part GMB nutes, she has had B52 and Big Bud so there are plenty of sources there for her.

Molasses is a good idea. I´m gonna give her a feed at lights on and will add some in.

Cheers for the advice man!

Fungus gnats?

Kind of looks like fungus gnat damage to me.

Mate I think you might be right. I have been so busy trying and failing to correct a nute imbalance I have been ignoring whats right in front of me. Looking at the damage and the fact its getting worse despite my best efforts, it could well be pests! Lights are off now so I will inspect further later.

Thanks so much for this smokey! -

Hey mate! :smoke: This looks like combo Ca-Mg defc.,... LOL!- there's a reason they pair these two together, as one is often linked/followed by the other,... yeah, some of the necrotic damage does look a bit like P defc., but the leaf color is the tell (yellowing pattern), as is the spotty nature of the necrosis; P defc. usually causes patches of wasting/necrotic tissue, even when still fairly green at times! Also, Ca is very poorly mobile, so uppermost growth tends to be hit the hardest, while Mg is fully mobile, and will be drawn off lower fans first, yellowing them out from edges in, usually w/o spotting .... Ca-Mg munchies are not uncommon; had one plant that ate 3 times what the other seed-mate had, and at this stage, it's almost automatic! no doubt, the most common defc. syndrome I see here,... I have no idea why this happens though,... :dunno: regardless, this is not damage caused by fungus gnat larvae attacking the roots, in epic numbers... you would know by the clouds of adults flying around, and the maggot-like larvae that might be at the bottom of the pot drainage....symptoms simply don't match up...
...do you have a dedicated Ca-Mg supp'? the conc. of stuff in them is usually high, better that molasses; Foliar is out at this stage of budding, barring a desperate severe save attempt,.. but you're not there! If not, molasses will do in a pinch, as it has decent amounts of Ca, Mg and K in it, plus the sugars will make the soil herd and plant happy; mix at 1T/gal soil drench; make sure to quit at least 10 days before projected harvest, as part of the final cleansing process,....
(Do you have some gnats? Small numbers are no more than a nuisance, but no need to put up with them at all; nothing kicks their asses like Mosquito dunks, or the bacterial equivalent,...(that's how they work, there's a specific bacteria inoculated in them, that gets in the bugs' guts and wrecks them)... I found granular stuff at OSH, instead of the pucks that are a PITA to break down!
