yeah, I hear you... I did a full larf out and lollipopping today on 9, 1+ pounder sized girls........ we have about 8 days of good weather coming and I have found if I stay on top of things I can keep the Septoria from the sugar leaves, but at some point I loose it if the weather stays bad......
your plants are too big to get into a big larfing program..... but any amount helps in my experience.... Failure to snip down at the base of a leaf leaves the starting point for infections.... so proper larfing today was more work than I like on any one plant..... but it is what it is.......
Septoria resistance with an early finish, no ruderalis genes, 20+%, no heavy indica, is what I'm looking for.....
Ugh, found some powdery mildew on one side of a big MOH girl today..... just hacked that side of the plant off.....
Pineapple Muffin is really an all around champ for me this year, so far..... Tropicanna Poison is a septoria resistant champ, but ugh, aphids love her too.... I have a TP next to a PM in a row, not touching, and the PM has virtually zero aphids and barely any Spetoria ( had one split in another garden area and half the plant rested on the lawn for 12 hours before I could get to her and strap her back together... problems like that are always a sure start of infection problems... but minimal on the repaired bush).... next plant down, Made of Honor, Septoria and some aphids and now some PM,.... next plant down the row, Gorilla cookies Fast, both Septoria and Aphid problems..... I have two other GGF's which are much better, and 2 other MOH's having some septoria problems (and a late flowering start on all of them)...Odd though, if you looked at the plants from 20 feet away you;d think the Tropicannas are healthy as horses with sticky, purple flowers done in 3 weeks...get up close and turn those leaves over and there's an aphid party..... ugh.... Candy Store girls hanging tough but vulnerable.... mixed Nutz, mixed results, but an early flowerer, so done by 9/20. second round of autoflowers thriving, but not as much as the ones that had the june/july weather.... I have yet to see an auto flower that doesn't foster at least some septoria.... they move along quickly, so just hard larfing and regular LST work keeps them dry and lets them finish in the summer's sun, but work.
Read up on Super Wreck for septoria resistance , Mendo 20....also, some of Humboldts may be good to consider... it would be interesting to run Pineapple Upside down cake right next to Pineapple Muffin to see if they have different septori resistance... it would help clarify where the septoria resistance I am seeing in Pineapple Muffin is coming from. I gave 2 PMs to a buddy, one from seed, one a clone. They are both high septoria resistant like my 3. The cloned one started flowering a week earlier than all the other seed started girls. PM's only read as 22% so likely not the best wash/press material.... We'll see how they finish.
I think all these septoria problems are being fueled by wildfires and a humid planet.
