Sudden Yellow/Browning Of Leaves

[High Country]

As the spray evaporates on the leaves it will leave a slight residue, this is quite normal and nothing to be alarmed about. Personally I would remove the affected leaves and dispose of them. This will help prevent any further spread.

The effectiveness of the spray will be determined by everything returning to normal over a period of time. Don't forget when they go into flower the fan leaves will eventually start to yellow as the plant puts all it's energy into the flowers.

Keep us updated.

My plants don't go yellow unless there is a problem or I take away nutes and start flush. The yellow leaves with (esp with brown rust spotting) is a clear sign (esp with the pop-corn sized buds) of a cal mag/n issue.

I'd rather smoke Greencure or sulfur than mold or mildew any day.
Did you ever pot them up? Too much rootmass in too small of a pot and a little nute buildup and you'll get a low rootzone pH and get cal and mag defs.

HC, JC, and Hazy...thanks for the input guys! I have seen pics of plants yellowing during flower and staying green till flush. I noticed Fox Farm feeding schedule reccomends giving Grow Big during mid flower, probably to decrease yellowing. I plan to hit them with a heavy feeding og CaMg today, not sure if should give some N since I can stll see the "claw" to some leafs? And should I give the flower nutes?

Hazy, I haven't potted up, I defitinly plan to on my 2nd grow around. I have to agree, I would rather smoke the spray than mold/mildew.

JC, should the buds be bigger for 21 days of 12/12?

Thanks again everyone!

You are fine....then again I never grew that strain before. I am going to look at your pics in a sec....

 

[Sirus]

JC, they get to eat tonight so new pics will follow tommrow. Check the album there is a lot more in there. Burn one for me bro.

 

[Mr. Greengenes]

pushlimits gave the best advice right at the top of the thread, repot! It was a bit late as of the time you showed the first pics, and now it's what, a week later? Even now, it could mean the difference of 100% in yield, unless you can water (and feed) those potbound babies like a genius. Hate to disagree with so many good growers on this thread (and I see some heavyweights in heah!), but unless you're in a very humid area, I wouldn't stress the fungus too much. Just chop the affected leaf(s). If you feel you have to use a 'treatment', try dusting with sulfur. Just hit only the affected leaves without getting any on the buds. We don't get much fungus around here (except PM), so I've never tried Neem, but I hear it works too.

Burning one right now;actually..some bubble..puff puff pass bro-seph...btw, take a pic of your root system...then we can clarify for everyone in here and more importantly YOU if you needed to transplant or not. I would love to see if you are severely root bound. What size did you go from right before hitting 12/12. I usually go from 2 gals to 5's about a week before...depending....

Yes, neem does work on pm and less damage to plants than using sulfur....I use neem on a regular basis for mites and pm. Works great! Makes plants shiny too!

Thanks for the input Mr.Greengenes. I think re-potting would be good. The pots are 2.5L but they were nowhere filled to capacity, learning curve mistake on transplant. The earlist I can get some FFOF is Tues and that's if they have it in, they have all the others cept FFOF. I have neem oil, but I thought you couldn't use it during flower though. That sux sulpher messes them up. I was so looking forward to tasty smoke.

JC, I went straight from the starter pots to their current home around wk 3. I will try to get some root pics tonight. If transplant is needed it won't be possible till the end of the week, but they still have 4 wks left prolly.

 

[Sirus]

I'm pretty sure they are root bound, I cant upload the pic atm but I will ASAP. I still have FFLW, lime, EWC, and perlite...can I use that to mix up a small batch or should I wait till I can score some FFOF? I only have about 19" till I'm hitting glass, how big should I move into? Honestly they are prolly only in 1.5-2L of soil atm..

 

[Sirus]

Here's the pic of the roots...

 

[Sirus]

So mixed the rest of the FFLW... 1 part = 1 gal

5 part FFLW
2 part EWC
2 part Perlite
2 tbl Dolomite Lime per part

I mixed well with a bit of water and I will transplant and give them a little straight distilled tommrow. Should I manipulate the root mass at all when I transplant, or just leave as is? I'm thinking about 3-4 gal since they are prolly in 2 gal or less now..

Trimmed off all the "black spot" leafs.. Is it possible the smoke wont be affected by spraying since they still have 4 weeks to go? Should I "rinse-spray" the leafs with straight water during flushing before chop?

Thanks to everyone for all the help! IC Mag is a fantastic community!

Here's the pic of the roots...

HOLY SHIT GUY! 4 weeks left? You are pretty much at hand-fed-hydro at this point. Until you get them in more soil...feed feed feed. How are temps? Below 76-80?

 

[Sirus]

Hey JC..I am assuming about 4 weeks... I am at 3 wk 3d of 12/12 today. I plan to transplant tommrow, water with regular and then jump back on the feeding.

When dealing with a N toxicity you get the "clawing" of leaf tips...will this straighten out? Or should I lay off the N since the new soil will have the EWC and just stick with flower nutes?

I defitinly have a long way to go...thought they were looking good bud wise. Oh well hopefully 1oz per plant and I will do many things differently next time...

My temps are higher than I would like... upper 70's to mid 80's with lights on. I will be relocating next round. Ambient's will be much better, the a/c will be able to keep up

 

[Mr. Greengenes]

Wowee zowee! Nice looking roots. This late in flowering, just up to a 1G from the 2L would probably be enough. Roots don't grow much after a point. Also, I wouldn't break the rootball up at all. It will grow out right away as much as it needs to.

 

[hazy]

I'm torn on this one. I know I suggested you repot but I hate to repot more than a few days in to 12/12. If you do, take MrGreengenes advice and don't disturb the rootball.

 

[Sirus]

So I got some proper pots and I will be transplanting tonight, wish me luck. They are uber thirsty so I will be watering with straight distilled, I don't want to add anything else to their trauma today. Feeding will resume in 3 days or so.

Yo Sirus
The only thing I have to add...and I hope I am clear on this...really baked right now. Mostly indica automatically goes into flower mode and stops making roots at 12/12. Mostly sativa goes 1/2-1/2 when you go 12/12/. Sat will still make roots...if anything (this mostly indica?) you are giving her room to breath so it will look like you made more roots. But even a mostly sat will not make roots this far into it...at least not that much...you are still doing the right thing man. Not familiar with your strain but it looks mostly indica.... Greene geenes is correct...do it up sirus and make that gurl phat bro-seph! Puff puff pass....

So a successful transplant for LA and Blue Cheese... Chocolope had a fan fall on her about a week ago and damaged a couple branches, which are now staked, so I left her be. LSD wasn't pot bound so I left her alone as well. They all got watered with straight distilled, they needed it too, I have never seen BC so thirsty!

As far as the Black Death goes the spray didn't seem to do much, either that or it just looks bad because she was so dry. I thought I trimed all the affected leafs off but there were many more found today. If it did spread so quickly than I think she is done for. I sprayed on the 29th...the bottle says 7-10 days, I think she will be damn near overtaken by then if progression keeps up the way it seems to be. I had the thought to just prune all the "unclean" leafs and hope for the best, but there is so many the pruning in itself may kill her. I don't know what the problem is, my temps get too high (85 max), but the rh stays between 35-50%. I think since she is slated for death anyways, I'm just gonna prune the crap outta her. Funny but 2 weeks ago she looked the healthiest outta all of them. Easy come, easy go I guess..

Thanks for the info JC and I understood it perfectly.
Only 2 more days till I get to puff-puff-pass!
