When do you guys usually stop topping your plants? My plant’s have been pre flowering for a couple weeks now but are still in full blown veg.

On a side note, how does acid rain effect outdoor container grown plants? Just recently found out the area i’m in (northeast) has bad acid rain, I ph’ed the rainwater yesterday while we were getting that monsoon and it was around 5. I’m assuming the limestone/bacteria/fungi and organic matter in the soil buffers the acidity? It was nonstop thunder and lightning and downpouring all day, the plants seemed to absolutely love it, noticeably greener afterwards..

Lastly, what do you guys do to prevent/control Septoria Leaf Spot? So far so good, i’m just concerned for the future, especially during the flowering months. I know it only effects foliage and pretty much it’s end-all is complete defoliation. How easy is it for it to spread from plant to plant via wind? Or is it a leaf litter/plant contact type of disease? My plants are mulched and up on a deck, away from native plants. Thank you!!

I am in Maine and have never had any problems with rain other than too much in the fall. I wouldn’t stress out over acid rain. As far as topping, I would not do anything once the stretch starts.

Awesome, that's a relief.. yeah I got to figure out what I'm gonna be doing come late summer/fall. It gets cold and rainy up here in the ADK. Hoping for another Indian summer.. And ok cool yeah I wasn't sure, they don't seem to be stretching yet, just vegging vigorously. If anything I may just keep bending the two tops until the side branches catch up. Don't want massively thick colas..

Mostly just keep the friggin leafhoppers off, they seem to spread all that crap.

I treated the garden soil, tree bark and surrounding bushes with LalStop G46 couple years ago.
Pretty much took care of the enedemic PM on the lilacs, stopped fusarium and septoria in the garden. Hasn't come back since.
Added to garden and compost in april last 2 yrs , grows at colder temps 50f and eats all the nasty stuff.
It will colonize the roots, soil, plant. Between the early LalStop and numerous later B. bassiana treatments, it's tougher for septoria or PM to set in.

Leaf septoria eventually affects the flowers by attacking the sugar leaves, which then die back into the buds and creating "dead spots". Septoria is more prevalent in wooded areas, especially during the summer, if it is a wet summer. I have been spraying sulfur, with NO copper added to it as a preventative, with mixed results. Last year the sulfur didn't seem to help much. This year is much drier and the septoria is minimal. I have friends who have grown plants in the middle of large open fields who had no septoria, while I had a lot. I have found that certain plants have been almost totally immune to septoria while others around them are devastated. I am growing some of those out again this year.

Damnn, those leafhoppers are a giant pain in my ass!! I've been crushing a couple everyday, they're really evasive too..
Good to know, i'll look into that.. Thanks!

Damnn that's no good....I'm surrounded by forests, luckily this summer has been on the drier side with periods of heavy rains. We had drought-like weather for a couple weeks. Cool, I was thinking of using sulfur dust but now I'm on the fence..I don't like to add anything if I don't have too..I was thinking more environmental control (bringing the plants under cover during rain), blowing fans during humid days/morning dew, pruning, e.t.c..

Apparently the pineapple chunk, and peyote cookies are mold/mildew resistant, but that can be a crap shoot...what makes a plant resistant?! I never bought that, seems like marketing to me :confused:

All I know is I have had leaf septoria 3 of the last 5 summers and most plants were devastated, some died before harvest and a few I harvested early. Each year some plants did better than the others. I know now that I have to choose plants that do well outdoors in my area, not whatever might be the current fad. Septoria is much harder to deal with than any other fungal issue I have had. I will spray Zerotol for PM and any other molds, but it has no effect on septoria. Other than that I don't spray. Septoria spreads when wind and rain disperse the spores. Septoria is always present in my area, but the conditions don't always occur that cause it to be a problem. So far no spots on the 2 offspring of last year's resistant plant! There is a lot of literature on leaf septoria in tomatoes if you want to see how commercial agriculture has been dealing with the problem for decades.
