leaves cont. to burn up

leaves cont. to burn up

Did a good flush and rinse but still notice the leaves burning and canoeing. Its happening to all of our plants. The uk cheese barley has any leaves left on the colas and bud production seems to be stunted. We have mostly diesel a breed that is know to be a very late finisher need healthy leaves for buds! Thinking about giving it a twerked tea without the fish powder. Started using calmag and silica ag ain since we still have a bit till harvest.

Uk cheese smells great was the first to start flowering but has developed the slowest

Hey Jclee,
I witnessed some of those same symptoms in my outdoor grow this season. Can I ask what your soil is comprised of? I do believe that the curling of the leaves was initially the plant struggling to transpire in the heat. But I think I found the root cause of my issues to be in the pH of the soil. My tests came back with pH of 7.5 on some plants. I believe this can effect the transpiration of the plant leaves. It can also have an effect on the uptake of micro nutrients, such as Cu copper and Zn zinc. I believe that to be the cause of the burnt leaf tips, as I experienced the same. If you didn't notice the canoeing or tacoing on all the plants, I believe that is due to different plants having different sensibilities to soil pH. Fwiw, I had 17 varieties in the same soil and only experienced the leaf tacoing in the SDs and certain CS from seed.However, the micro deficiencies were experienced by mostly every other plant.

What I began doing was bringing the soil pH down with light doses of sulfur followed by compost tea to keep the microherd population in check. I also increased my calcium, magnesium, and micro nutrient foliars. The Ca and Mg were also being locked out by a K potassium toxicity that exacerbated the problems in my soil. The micro nutes were to help alleviate the lock outs and slow down the burning of those tips. I did also apply some age old bloom to a few test rows and it seemed to really help the health of the plants, but I didnt have them on much of a feed through veg or early bloom. 1tbs/gal was the ratio I used, at one application per week. I did like the results I saw, especially after those particular clones were in such bad shape. They even seemed to step up and look better than some of the healthiest plants I have in my garden that never got an age old bloom feed.

Anyways, my problems all started in the soil, so thats where I would start looking if I were you. BTW, I used the Earth Worm Soil Factory NorCal blend.

Thanks for the info! I agree my issue is in the soil I don't feel that I could have burned them with the amount of age old used, never more than 1 tablespoon per gallon every 2 weeks. What is the best way to check soils ph? I'm using fox farm ocean forest with earth worm castings and perlite added.

I'm no expert here and not may people are experts, especially when dealing with sick plants. There are many different reasons and likely multiple reasons why your leaves are curling and burning. PH can certainly be a huge factor. Have you been adjusting the PH of your nute mix? and your regular water? Unfortunately there is no immediate fix for sick plants so at the best you're talking at least a week or two to see any type of improvement. trying to figure what's wrong can be extremely frustrating and it often leads to over compensating. For now I would find out what the PH of your soil is and possibly make adjustments as needed for that but I would stick with straight water for a few more cycles to give the plants a thorough flush. unfortunately your plants are budding and this is all extremely valuable time lost. Sorry bud, hopefully things work out for you

I would say not the mites as the hairs are still nice
And there, when them little bastards show up hairs
Are gone from what I have been hearing and seeing

They do look like over fed or sprayed and the sun
Burned them

Hell I can't tell from my phone and every time it try to
Enlarge it exits the pic

First off thanks for the help I really appreciate people taking the time. It's been almost 3weeks since they were fed. Flushed them a week ago. Other than that I have been just giving them water silica and calmag. We have to adjust the ph of our water each time (6.6). Leaves seem to be canoeing more some of the leaves are almost curled shut with brown spots. We have also had the coolest weather of the season as well with some rain no relief for the leaves. Also I only spray in the evenings.

Most soil pH meters you find at the store are cheap and not very accurate, but they will give you a ball park reading. You can find those at any gardening store and probably even at any big box store. They do sell digital probe meters for around $100 I believe. I'll definitely have one on hand next season. I got my soil tested though, and that gave me the informtation I was looking for.

Fwiw, the plants that canoed the worst never really stopped canoeing. It was probably too little too late for them, and probably the same for yours. The SDs did start looking better however. They all did continue to stack very dense and heavy, and although Im sure some quality and yield was lost, Im still getting a decent harvest out of them. The GC that canoed the most is the weirdest looking plant ever seen. It grew some insanely fat buds but almost every bud has a very tightly curled leaf sticking up through the very tip top. Its like the taco turned into a burrito. I'll try to snap a photo so you can see..

Best of luck to you

 

[Jclee133]

Yeah I have one of the cheap meters says just under 7. Is it worth trying too get my soil tested at this point? And Should I stop feeding them the calmag and silica?

 

[Jclee133]

Tested the ph of the runoff water was 6.9 going in 6.5 coming out. Don't see an issue there. Anybody got any other ideas?

You may have root aphids. I had them indoors for the first time...Everything I did to the plants was perfect- I was baffled for a while just like you -took me a while to figure it out.

Root Aphids create phantom deficiencies that look very similar to your plants symptoms.

Go down in the soil in one of the pots deep and grab a nice size sample of soil and look around for a while with 100x scope. Or put up a yellow sticky trap near bottom of plant to see if there are any adult Root aphid flyers.

The only thing that worked for me was Acephate 97up at 4ml per gallon- complete root drench. Plants looked better overnight. But that was for my indoor mother plants, that were not in flower. There are some organic methods like botanigard 22wp that would help your situation but you may find out its really too late for stuff like that. Here is a good thread to explain different treatment options.

You probably have a wack of slow acting ferts still stuck in your soil still doing there thing. If you had a lot of them you many not be able to flush quickly and fix.... just ride it out and be more careful with ferts in future.....

Thanks for the help everyone!
