Need Some Help - pics

[m.steelers]

What's up crew - been laying low for a while... and some problems have popped up.

Here's the lowdown:

temps - 80 at canopy
ph - 6.2-6.5 depending on plant
Pro mix
Iguana Juice Grow with supplemented Mg up until this started

OK - so I think I ultimately may have to do a flush down to clean the medium, but I was trying to avoid that in case this is just a plain old deficiency, cause the flush would really set them back if that's the case.

A couple of weeks ago, I noticed the plants had a bit too much N and looked like they were showing signs of Mg def... so I backed down the base nutes and started supplementing Epsom salts to clear up the def, which worked well.... this def seems to happen often, so I decided to start adding Mg to my water on a more regular basis at 1 tsp/gallon. Like I said I had also cut the base nutes back for a little while, down to 1/4 strength and then up to 1/2. I feed the Mg and Base nutes seperately. Right after I made this feed change, the lower parts of the plants really started going light yellow. I first blamed this on a thick upper canopy with not a lot of light getting to the bottom, so I ignored it for a couple days... So I took the plants out for a closer inspection and to my dismay I found a couple mites.... not an infestation by any means like maybe 2 mites per every 10 leaves I checked. So I hit them with a Neem spray and havent seen any signs since.... but after the spray, it really started getting bad, and it happened fast. Like I almost shit myself when I opened the cab up.... perfectly healthy leaves the night before now look like this.












And in a little over a week a perfectly healthy plant now looks like this.


This is now affecting 65% of my plants, 12 different strains... It is only affecting the bottom and middle leaves, so I think it has to be some sort of undiagnosed deficiency. The growing tips are healthy. The leaves you see above drop very easily, you barley touch them and they fall off. There is a blue tinge to those spots you see on the leaves... I am starting to get frustrated as you can imagine because I dont want to see another get set that far back. I was gettting ready to cut some of them over to flower and now I think it best to wait until this is fixed up. So what do you think it could be? I have started them on a 20-20-20 fert regimen in hopes of clearing this up, the less serious plants I have given the 20 20 20 look like they are fighting it off now, so I think I am fighting a good battle... but maybe not. One I gave the 20 20 20 to last night and I woke up this morning to find more of these blueish mottled leaves with necrosis... maybe I released some trapped salts when I watered last and it is clearing out??? Maybe it hasnt started working yet, I dont know....

Here are my possible causes:

Phosphorus Deficiency
Some Micro Deficiency (Calcium??)
Neem damage
Mg overfert

PH is spot on so it cant be that, meter is calibrated... i wish it were that easy.

Please give me some feedback, I've never seen anything like this ... especially coming on so quickly... or maybe I just wasnt paying close enough attention.

Anyway, lemme know what ya think. As you can tell by my ramblings I am pretty irritated cause this is delaying everything in my flower room.

Thanks...

Hey steelers, been a while!

Hey steelers, been a while!

Well lemme start off with "I don't know"... I have a few clues and/or guesses however. I think it is probably a mix of a few things but of course it's hard to tell. It looks like the mites did do a bit of damage on the leaves, it also looks like you overdid it with the mag. I think that the burnt tips are a giveaway on that point if your pH has always been in the clear. It also seems to show signs of potassium deficiency. I dunno for sure but I do think that a transplant might help, unless one was done just recently... in that case, just wait it out and hope it will show you some sign of better or worse. It may have a virus There could have been something bad in the bottle you used for neem.... I couldn't really tell ya but I can try to help

don't flower them until they are on the road to health or yield will suffer

is the plant in the pic a re-vegged plant?...how long have they been in those pots

those plants seem to me like they not getting what they need and require a feed.....throw away the neon colored fert powders and go organic with a top dressing of several organic ferts and water it in..this will give them the nutrients they need and you'll see faster healthier growth

with several pots...try this - add top dressing or mulch of worm castings and compost with a little of other stronger ferts like blood and bone, manures and guanos with a dash of dolimite lime ..and continue with the Peters or other packaged neon chemicals on the other pots and let us know which grows best...my money is on organics

Peters and other ferts are good for a quick fix but can cause problems as they are very easy to under or over dose..whereas organic farming is more gentler and forgiving..as well as being better ...the end result tastes and burns better too!

well, dude when I first looked at the leaves, I thought mites...... get some spider mite predators if you can..... and if your leaves are getting mites, well then I know the rest of your plant is succeptable to something..... so grab some nematodes while your at it and make sure you properly flush before adding..... I also have an incling that your plants are getting too much humidity..... try cutting that back a bit and maybe adding a little more co2.....hope this helps!

It has to be the spray.
What kind of spray specifically?

 

[Sleepy]

man that sucks.

tough to pinpoint, but a good flush won't hurt.

pH of your runoff is good?

sorry, i'm stumped.

best of luck, m.

Yo Bros,

Thanks for all the replys... They were mostly all transplanted a couple weeks ago so no root issues, humidity is at 40% and there is a lot of air running through the cab. Luckily things are turning around....

From what I can tell it has turned out to be a plain old def that went severe quickly because I moved them up to a more powerful light. I have seen lesser cases of this before. I was using the AN organic line with pro mix, and I swear if you skip more than one feeding it can happen fast. I think the reason must be that there are zero nutes in the Pro Mix, so there is little to nothing to feed on if they need it. After 2 consectutive feeds with 3/4 20 20 20, and one feed of Iguana Juice at full strength, all of the lesser cases have fought it off, and the damaged one is on it's way to recovery. I hope I have learned my lesson this time... I have deficiencies pop up when I try to be too conservative with my feeding. I will consider it a blessing, cause if this wouldnt have happened I probably wouldnt have found the few mites I had, and that could have gotten a lot worse. but now they are eradicated... and I will do one more neem blast in 4 days to make sure. I think letting a bunch of predators out right before I cut over to 12 12 is a great idea, cause spraying is not an option for me then.

I do think some of the damage could have been neem related, but most of it was from a macro def, probably P or K. Anyway, the worst is over... That one plant you see was just a mom and wasnt getting flowered anyway. The ones that were going to get cut over were just starting to go def, thank god for that. They look nowehre near as bad as that Kush, they just had a few leaves showing. Delayed me about 2 weeks but it could have been much worse. On to healthier days!

Thanks again for replying. I was stressin and it's just good to hear some other opinions.

Sup Buddy,

looks like mine did after i sprayed for mite..looked healthy the day i sprayed them came back the next day and i thought they were all going to die... glad you got it under control now... all my plants bounced back within 2-3 weeks.. Keep It Green and Stay Safe..HE

it could have been from the neem then since you were adding a descent amount of mg it could have casue a few other important nutes to be locked out such as p or k... back off on the mg and definintly flusha lso check you ph from the run off . it will give a descent indication on what the prob could be..other than that flush her and start on the same nute regiment small and build up but add less mg like around a 1/4 tsp per gallon..

looks like it may be an advanced phosphorous def, coupled with mite problems.
