AK47: Dr. They're Looking Sick

[spiritlevel]

Hello

I'm after some advice. I'm currently blooming AK47 and they are on Day 34 today.





The plant in question suffered a bit of burn from a 125W envirolite when she was vegging about 45 days ago. Ever since she entered the bloom garden she has displayed yellowing of the upper most sets of leaves on the main cola.



At this moment in time, the yellowing has turned to browning. Can anyone explain this to me please? There are a couple of photos, the best quality I know how to get atm.

Thanks

Ya, that is normal after the leaves have been damaged they turn necrotic and you can't do nothing about it. There is nothing wrong with your plant; it's just after math of damaged leaves

Thanks so much MynameStitch. I asked the same question on another site/forum and after lines and lines of text from posters, I didn't get a direct answer. Time for a lil wiki digest with a new word for the day 'necrotic'.

peace

better try and remove the affected leaves though...when burns toutch the bud it will end up in mold quickly.....just like at the end of a harvest...yellowing/decading leaves could also affect ya buds and cause mold...Just a thought ...:smile:

 

[MynameStitch]

Did not know that core; how did ya find out about that?

 

[spiritlevel]

what are the chances of this 'necrosis' spreading to the rest of the cola and causing it to age prematurely or start to rot? Or have I smoked too much this afternoon. I just do not fancy loosing any plants in the bloom room at this time of year.

thanks again MynameStitch

That was what I expected to hear quite frankly. I'm going to do some trimming. The decay is spreading in an inward fashion. to the scissors

by growing and F'ing up Stitch :wink:...

I thought that it can only truly affect it if the buds are dense or if there isn't good airflow. This would make the most sense because if it were to happen it would rot.

 

[MynameStitch]

The necrosis if it's still from the burn will only spread to the affected part of the leaves that got burned and no where else.
Core's mistake is the first I heard of dead decaying leaves causing bud rot.... because when they decay they are dry unless you got high humidity...... now if you left the leaves on there like you just chopped the plant and it's transpiring moisture.... I would think ya it can cause bud rot... but when you get a damaged leaf like; it dies slowly and has no moisture to it once necrosis has set in it's just a dried up leaf; so what confuses me is how a dried up leaf can cause bud rot......

I am not saying your wrong core; I am sure it did happen to you, you know your shit; I am just saying it's confusing me, because without moisture from the leaves I don't see how it could cause bud mold; if that was true; then the leaves from curing in a jar would always cause bud rot..... when you trim you are going to leave some leaves on the buds no matter what... so when it decays and such you would think it would cause bud mold....

if the decaying leaves was the culprit....

I'm now at day 46 of bloom with the affected AK47 and her peers... The removal of the decaying leaf matter caused it not to attack any other part of the cola. In essence, whatever this particular plant is suffering from is causing it much slower development than her two peers. Though, as a result of this slowness, her bud sites are quite larger than those of her peers. At this time those fluffy buds are only just beginning to dense up, whereas her peers were dense long ago (2/3 weeks at least). It is probably visible in the two accompanying images. Thank for the removal advice Core, it was surely spreading but now it's gone, thanks everyone else also. Will post some harvest info before the new year, it looks like it will be ok but not worth the 15L pots they are in neither the 1.2kW hps. Seasonal Greetings

i wouldda repleyd but i mist it...now i don't have to anymore Stitch ...i knew these decaing leaves cause rot.....i've had it happen a few times at first...but i got that solved out real quick


@Spirit
thx for that Post Spirit !...good to know its going good with ya girls!

 

[MynameStitch]

Well; ya learn something new everyday and that goes for me; cause I had no idea that happens from dead necrotic leaves.........

 

[p0rky]

well she looks good other then the burnt leaves. fairly stocky. this ak47 from serious or other breeders? Thanks!

I cannot say for sure that it was 'Necrosis', but the plant that has been a problem Was burnt early on and didn't make a full recovery imo. I can only assume the problem was derived from the burning, therefore derived out of this necrosis. Even if Necrosis wasn't the main issue at the time of seeing it as a major problem, I am under the assumption that it had some involvement in the decaying leaf matter pictured above.

The leaves that were decaying were not crispy or dry. It was like a wet-rot. The leaves were still flexible but very much discolored and that discoloration was starting near the leaf tips then spreading back to the stem/cola. I'm uncertain as to whether or not this decay would have cause the mentioned bud rot, but to be on the safe side I fought against it. I think it was likely that bud rot would have been a result just down to the way the decay was attacking the plant.

Those AK arrived as tiny rooted clones and I'm not certain of the plant origin. I'm uncertain how the clone producer raises their plants.

Happy New Year

The problem plant weighed 70g crisp dry... i don't think i flushed her long enough as I just wanted her out the road.. the taste is a bit shytty to me but other members of my quality control team haven't said anything in that regard.

 

[MynameStitch]

How long did you flush for and when did you cut off giving her nutrients?

 

[spiritlevel]

can't really remember the dates as i didn't have a grow journal to help me out, but I think I only gave her 3L of tap water and wated until she was quite dry then chopped, whereas normally I give 2 or 3 largish amounts of water over 10 days then when the soil is dry, chop.

i was thinking the same thing.

stitch, i be it was from experiance, ive had thoes leafs mold/rot on me too, the dead surface is a good breeding ground for baddies.

my AK47 was a freaking winner, i hope yours is aswell, its off to a decent start, besides the minor prob.

 

[MynameStitch]

Ya, that is crazy, I am surprised. But now I think about it; ya, because when leaves die they transpire moisture from the leaves and the moisture is on or near the buds, so it would do it.

Thanks for swinging that one too me guys
See! Ya learn something new all the time ya know
