6 weeks into flower checked today and found this

[Koroz]

Algea on roots (Slime) bad. Wasnt there last change out of res.

No pictures, Flushing with Hydrogen Peroxide 3% right now.

Been slowly having problems with these leaves showing up like this







and redish / purple tint starting at the end of the branches



I have always had perfect PH tap water. Tested it the first 4 changes and had stopped. Could this be due to a change in my water PH levels all the sudden?

 

[Guest]

Slime mold or algae or both? The necrotic tissue in the center of leaf is nasty looking and not a good sign.

 

[Koroz]

well the roots went from white to brownish, after treating with HydroP and adding hydroguard they have started to turn white again. This all started when I had a fungus on my trunk. I just followed the algea treatment on the Marijuana Cultivators FAQ page for my root slime / color problem.





that was 2 weeks ago. I have since been treating with direct applications of Hydrogin peroxide, until my hydro guard got here. I then started applying it directly to the trunk, and added to my res.

It now (will have to get pictures later) has cleaned up on the trunk anyways. The trunk is now fattening back up, no more spread of the fungus and the white powder / black gashes are gone and it looks to be healing.

The leaves started looking like this as soon as the trunk showed up with this problem. I checked around and found 2 white spores, started misting with HydrPeroxide mixed with water and checking every night and no more spores have shown up.

ok well my grow diary has two responses, both said it was nute burn. I was told to flush only with water from now on.

Now after 2 days of nothing but water my leaves are all yellow, including the small leaves in the buds and most of the fan leaves have dried up and fell off. I kept the water level right under the net pot like I always have.

Leaves have started to curl, I thought it was heat stress but this plant has always been in 85% temps with 30% humidity and not until the fungus showed up have I had a problem with all these things.

I am worried now that I got some bad advice and should not have started flushing with water yet (its actually about 40 days since sex showed) and I may have made the problem worse?

I really need some help here guys I don't want to lose this baby, I am wondering if maybe I should cut early or will losing all my fan leaves and yellowing of all my smaller leaves be ok with only a couple weeks left? Should I just leave it alone?

here is a picture of two of the buds, I know its HPS lighting so you can't really see whats going on with the leaves, but tonight when I do a res change ill make sure to take better ones, these are all I had right now.

 

[Guest]

that sucks man..ive got bad advice before and it hurts...im not hydro expert but what about changing the rez and adding some ferts...the yellowing could be a N def or somehting and maybe adding some would green them up??? again im no expert just my 2 cents.

yea im not even sure at this point that its bad advice, I am asking because I really am a newbie and don't know. I know that one day everything was perfect, next res change all went to hell in a hand basket. No change in nutes, no change in anything.

The only difference between changes was a new case of root rot and then adding 3tsp of hydroguard to the res. Maybe that was it... I think the biggest problem right now is the water temp is just too high, the AI is fine at 86 degrees F. The roots arent im sure... but I guess I need to track down what happened in that last res change that was different because they have been in this enviornment since day 8 of veg (was in a pc case 35w CFL during sprouting) and had no problems.

Hydroguard would help with those high rez temps, i don't think thats the problem.


It's definately a bad situation.....what is that on the trunk? mold or mildew?

how high is your water level inside your rez? what is your RH in your grow

room?

You said earlier you don't check ph cause your water was perfect, I would

check the ph, just to see how your swinging, especially in hydro man!

yea ill take some tonight doing a rez change. Basically for now though they went from very very white to a light brown, almost beige (Spelling?) Slime was on the outside, not horrible compared to the color change. Once I added hydroguard and started with the HP 3% treatement the outter root clusters started going back to white, still slime but the inner ball is still brown but not getting worse.

RH (Relative humidity I am guessing?) is a problem but on the low end for me, I never can get above 35% with averages between 27-34%.

as for the trunk I have no idea, I will explain what happened. I had my drip tube too close to the base of the plant and it was getting constant water on it, it started out as a small band of thinning tissue around the base, slowly started to get thinner and thinner and then started opening up with deep black gashes and a white powder.

Once I started treating with strait HP 3% to the infected area's it the black started to turn brown and the skin of the infected area started to peel off and show healthier skin under it, the thinning has stopped and it started to get thicker again, now there is white powder as of last night on the grow rocks so I ran water w/ hydro peroxide mix through the net pot and plan to flush again tonight.

so far ive done a 5ml per 1gallon (2 gallon total) for half hour wash of the roots, then washed the res and refilled with water, hydroguard 5ml of hyperoxide and that was 2 days ago. My water level is always right under the netpot, to about half an inch below it depending on if I refill every couple of days or not.

as for the ph, yea I really feel stupid now for thinking that because a couple times of filling my nutes / res it had perfect ph with out using ph up or down that I didn't check it every time, im really kicking myself now because I do not want to lose this baby. I have noticed that the growth has almost stopped on the buds, but no damage looks like has happened to them yet.

Sclerotinia sclerotiorum. stem rot.

[Koroz]

thank you both for the input. I am going to read up on both.

 

[Koroz]

problem 1 - Changed res a couple days back from a black 2 gallon bucket to a 3 gallon bin, used grey duct tape to tape up res, obviously from this pic and the state of my roots getting worse over night, I didn't tape enough. Suggestions on what I can use? black paint maybe? Or could black and red Duct tape work? - This was 2 days ago that the roots starting turning BACK to white, and now im back at square one with them looking like this again.





Very hard to tell but I'll do a before and after type shot.

BEFORE Water Flush:




AFTER water flush:




What I see here, and is hard with out the same top view down pic (sorry can't right now will have to wait until the kids are sleepin) is no more nute burns, but now no more fan leaves either all dead and gone, what ever leaves are left are drying up at an alarming rate and curling under like heat stress, but heat has been less of a problem then it was before.

Two shots of buds

 

[Koroz]

ok cleaned the res again to try and combat this slime, also double taped the sides and bottom so light leaks into the res should be taken care of.

Here is the total damage so far, with a blotched out trash bin since I don't think you guys want to see in a guys bathroom trash.. I dunno maybe you do but too bad




here is the bud that has pretty much quit growing on me it seems




and for some reason with a 5mp camera I can not seem to get good macro shots even in macro mode if I get any closer then this its 100x more blurry.. guess a tri pod might fix it? or I just have a crappy camera





at this point the trics are 60% cloudy 40% clear. She has a while to go yet and I am curious what my options are if this is as bad as I always expect it to be.. should I cut her early leave some veg in place to get clones then dump the plant and clone out a mom? Or do you think with what you see here she can last another 2 weeks with out being cut early? ( I know its hard to tell with pictures I am sure - and I am a serious worry wart)

Sup koroz,

If your roots are still turning brown it means you have a light leak.


in the first pic of post 12 you can clearly see light. If you have so much as

a pinhole light comin through it'll grow algae.

I suggest cutting cardboard to fit around your netpot/trunk.

My small netpots filled with hydroton and rapidrooters still had light leaking

through the hydroton.

ok thank you.

Is that in your opinion what is causing the yellowing and drying up of the leaves also?

 

[sugabear_II]

hey koroz - a couple of thoughts...

Aluminum tape is the best for light proofing your res.

Rot at the base of the stem is bad - really bad - likely pythuim as some have said - I had a plant catch this before and it became systemic - every time I'd take a cut it would grow fine and then a dark ring around the stem and the top would begin looking hurt then I'd go to change the res or something and the whole plant would just break off at the base of the stem/trunk. I found the best cure was to take a small fan (computer size will work well) and place it right next to the base of the plant so that air was blowing on the stem continuously, I was in fact able to rid the plant of the pythium this way and grew out several cuts afterwards - I suggest you try this right away

When the stem rots the plant can't get nutrients and water and it basically dies from the base of the stem up - getting it back to a healthy state is key to the health of your plant.

When the roots get dry or begin to rot the leaves show it first with necroposy where there is no O2 getting to them from the roots.

Keep treating with the H2O2 in the res. Keep the hydroguard going ( I personally like hygrozyme better).

Keep your air pump in the coolest place possible (outside grow area) as the cooler the air being pumped in the cooler the res.

And a cheapo tripod will help you get a good macro shot

Thank you so much SB.. do you think im screwed with only 2 weeks to go on this baby? I am going to add the fan to the base as soon as lights click on.

I am still wondering I guess is if I can pull this out in 2 weeks, and if I can is it even worth it this run considering its so late in flowering? If not I would rather cut now and get something while I wait on clones from a reveg / new seed and fix what I did wrong with the next grow, on the other hand if you think I can get this plant back on track in the next week and it will benefit in the final week even with all the damage that has been done already I wouldn't mind doing that either.

I know its hard to say with out sitting in front of my plant, so I take all advice and reference that against what I can see in person but would love your opinion.

 

[Koroz]

ok so I guess I can kick my own ass now.

Thanks Faulty switch on pump.. one that reads on, yet produces no water pressure. Good thing I found a way to get it to stick in place.. looks like at some point it broke and the pump has been off for god knows how long.

/sigh so lets see if circulating water is going to help.

 

[sugabear_II]

broken pump - now that explains everything - just hold on tight for the next two weeks and it will be worth it as compared to chopping now.

Not sure if you'll get a reveg (I could never get a DWC plant to reveg) but give it a shot.

 

[Koroz]

what the difference a working pump makes.

roots are again going white, no new dead leaves, and the plant is lookin a lot more peppy again. I lost 99% of my large fan leaves, Ive lost about 50% of the little leaves on the buds but It looks 100% better then yesterday you can tell the difference. I took some pics, I had a KILLER macro shot that purejpg seem to have copied over with a different pic when I was running it.

/shrug but I got a couple decent regular shots

Upclose of one of my popcorns




center shot on one kola



size comparison on the smaller of the 2 major kola's - As you can tell on this pic half the leaves on the underside of the bud are dead, ive removed those. But there is a LOT more green coming back to all the ones that arent dead and im stoked.
