So im not versed in outdoor growing so the issues that happen outside im stumpted on. Im not sure wht this is but it seems to be affecting all my outdoor girls now. Its light fading spots that leave a brown lesion on the under side. Ive been on top of shit in the pest control and i know my soils a decent mix thats been doing great up until we had a few dewy mornings. Need help please!!!
Organic decent soil? If so it is not a deficiency. Outdoors northern hemisphere? If so, remember you've only got so much time left anyhow. If I had to guess I'd say some kind of fungus. I've had it on my (outdoor) plants, or at least similar many times and it never hurt me. I would absolutely start watching out for mold. J
My soil mix as follows. 2cuft sphag 20qts perilite 3gal of pumice Half bag of lava rocks sifted out big chunks 1cuft of eb stone ewc 10qt malibu compost bu blend 1cup each Alfalfa meal dr earth Kelp meal down to earth (dte) Neem seed dte Crab meal dte Oyster shell dte Gypsum espoma Soft rock phos esp Bone meal esp Bio fish dte 4 Tbsp of dte root zone Wet down with ewc aact with added aloe and lacto bac culture serum. Cooked for 1 month before the 5gal pot then then the rest sat for another 6wks before needing to be x planted into the 18gal totes. This looks like maybe some glacial rock and sul po mag would have been nice to add next time but never experienced a deficiency that made more of a mark under the leaf than the top
Looks like the beginning of one of many black spot fungal diseases to me. The pics are kind of fuzzy though so can't be sure. Chunk
Whoa - wait a minute; I don't see the rare Himalayan Purple Spotted Thrush egg shell meal here? What were you thinking? It must be a deficiency! Hehe Dude, it just ain't possible to get a deficiency if you used a quarter of this ingredients. HHH, I think Chunks right, and was my first thought too. I think it's kinda common outdoors at the end of the plants cycle, as a matter of fact I've see dark spotty looking stuff on flowering leaves outside a bunch before but it never hurt my buds... I guess just keep an eye on it? It really doesn't look like a big deal right now - everything else looking healthy? J
If you have one of the mini microscopes for checking trichs, give the spots a look. If they've got dark fruiting bodies at the outer margin on the spots and a lighter colored middle it's likely a fungus. Sometime there will be gray mycelium in the center. Other species of black spot eat shot holes in the leaves. Less common are bacterial black spot diseases. Fungal black spot is easier to treat but I wouldn't try to treat it by spraying. I'd remove the infected leaves and either dispose of them or burn them. This includes raking up and disposing of any fallen leaves. This prevents any further infection of other landscape plants and next years crop. Props on the gourmet soil mix, sounds like it served you well. Chunk
My thought exactly on the mix i have another plant in a pot of straight from the bag cedar grove that isnt doin it nearly as bad. Under the micro im only seeing black stain in the leaf but underneth the surface and the a hair like trichs still intact. I feel if anything oger than fungus would be too much cal mag locking shit out but again wtf??? Bud production is steady but still a tad slow this late in season. It is a sativa dom strain tho
Well shits gotten worse looking like a lock out deficiency now. Any thoughts? I didnt add any rock dust or azomite or sul po mag. The only real minerals im sure are coming from just the kelp ewc and oyster shell. Its been in the soil now all season. Could it spent by now? I spread about a cup of ewc and a 1/4 dr e kelp meal with pro biotics yesterday. Crossing my fingers shes got the potential to drop a pound this run i dont wanna ruin it h ha
HHH, it's hard to imagine that you are having any kind of deficiency in that mix. Remember that you are getting minerals from: oyster shell, kelp meal, crab meal, gypsum, and alfalfa meal. I really think that the guys are right about it being a fungal problem. A kelp meal and ewc top dressing is always a good call in my book, hopefully she will respond to that. I'd definitely go with chunk's advice about removing infected leaves and raking up the fallen leaves off the ground so that it won't be a problem next year.
heres a video upload. the dinging noise is my battery dying ha ha but you get to see more of whats going on outside. outdoor problems - YouTube
HHH - it is my personal opinion that you are over thinking the deficiency thing. I believe that it is simply "that time of year" and your plants are going through natural senescence. Your plants look just fine. That small amount of yellowing and discoloration on your lower leaves is totally natural. These plants are annuals - they are nearing the end of thier natural lifespan and will slowly continue to do this, with no effect on your flowers. There is nothing you can do, nor would want to do to change this. My .02c. J
Hey HHH, are you in a hot, humid climate? We get this every year down here during the fall. I'll have to take another peep at the pics, but it looks like the typical fungus that normally only takes root on the fan leaves. In a sense it can cut back on yield because early outbreaks of it, esp, during persistent dampness, can naturally defoliate the plant before it would normally shed those leaves. I've never seen it kill plants or get into the bud. I have a sneaky suspicion that whatever type of fungus it is rides on the footsies of grasshoppers and flies, since everywhere they do damage it magically appears. At least that has been my experience. HTH. Edit: I just saw the video link, and yes that blue dream has a really severe case of it for how far it is into flower. It's likely whiteflies have fed heavily on those lowers. I would just really clean all those damaged leaves out. I'm going to try some lemon water for a minor botrytis outbreak, and it probably wouldn't hurt to give those babies a squirt,
I know its not white flies or bugs i regularly sprayed with a mix of aloe, dr bronners, neem seed tea, spinosad and a few drops of lacto bac serum in the evenings, every 2 days. And i can say that confidently. I stopped spaying 2 wks ago since bud set. We have had a pretty hot period late in the summer and humid as hell too. I had to water every day and spray the outsides of the pots to cool the root zone. Then all the sudden cold snap night temps with dewy mornings i had to shake off everyone. The oregon licorice i know is a strain that has a force field like resistance to everything. Ive seen them happy and healthy in rooms full of pm and mites. Growin like a boss. And that one shows no signs of this problem and is in a soil that should have shown deficiencies long ago
i just wanted to chime back in a nd say thank you jerry for the spot on advice. after observing the way my raspberries and roses started to spot and wilt naturally as well as none of the other signs of growth issues associated with deficiency, i figured its just a natural thing goin on. i know my region isnt the best for a sativa like blue dream outdoor so instead of reacting drastically i just treated it as par for the course. i gave it a top dress of kelp and ewc and a tea and i think shell be finished fist week of oct. it wont let me upload a pic or give you any more rep so all i have to offer is a thank you big time. i might have pulled out the bottles on her if not for you ha ha ha
