A little help from my friends...

[tkowitha123]

SO here it is the backstory got this clone from my old caretaker who, I'm guessing didn't care enough to diagnose this problem just told me the plant has always looked this way no matter what he did/does to it. Supposedly it is a cotton candy strain, I had the opportunity to flower 2 of these with my caretakers tea's before I received 2 more as clones. It look's to me to be a molybdenum issue, but I'm really no expert ... any thought's would be appreciated.
the first 2 picture's were taken a few moments ago




This last Picture is of the same plant approx. 5 day's ago granted I've only had this clone for about 3 weeks but it had just entered flowering before it was cut as a clone and he said typically the deficiency doesn't show up till flower

I'm no expert either so take what I say with a large grain of salt. Never delt with a deficiency like this.

Based on what I know Moly deficiency is quite rare. If the soil is very acid it is possible though.

My guess would be Phosphorous deficiency but wait for a couple opinions before you start making changes. P breaks down slowly so adding something like blood meal or a high P guano will take a while to have any effect. It is best to be mixed into the medium. I tend toward using organic nutes but his is one case where possibly using a chemical based fertilizer high in P might be the fix.

Sometimes it is hard to pinpoint exactly what the deficiency is and it does look like it could be a micro nutrient. Maybe pick up a good micro nutrient supplement.
Could be the PH of the soil as well, maybe this plant is less tolerant of a high or low PH. Do you know the PH of the soil or the water you are using?

If the PH is too high it can lock out P.

Well as I stated this is my caretakers problem that I inherited, I know he grows in a mix of coco and promix-bx, I also know that he has a ppm meter and a ph meter that he uses quite regularly, but unfortunately that is about all I know about his grow. I've only had these clones just shy of a month and they started to showing this problem about 2 weeks into me getting them( basically just after they rooted and were transplanted. I know my ph going in right now is typically 6.5 as far as ppm's go I'm not sure what I've got. I can tell you that the clones were planted in a ff light warrior mix about 70 percent light warrior and 30% shultz seed starter. I can also tell you that I've been using Nectar for the God's Calcium based Liquid nute's; about 3/4 of their complete lineup at about 3/4 strength or slightly less, in RO water purchased from the local market. Dunno if any experts out there have any better info for me, I hope so. I feel as though the plants are no longer deficient but would like to be prepared since I know this strain happens to have a high demand for... something... maybe molybdenum?

you are correct its a moly def.

 

[tkowitha123]

I actually was able to procure some used soil from my x-caretaker and did a slurry test, the ph of his soilless medium was at 5.4, granted thats after a grow and after the soil sat around for a month or 2 in a garbage bag in the basement but that seems ridiculously low for ph. He's been growing this cotton candy strain for a while now so its very possible that the used soil I ph'd actually grew a C.C. plant that had molybdenum issue. I'm using different soil than he use's for my clone's and seed's, so I believe between a new/different soil mix, and a completely different/organic nute line, and proper ph level's, I've hopefully solved the molybdenum problem from showing itself again. Any body else sure of it being a moly issue or do other people think its a phosphorous deficiency? Thanks Cascadian and tikitoker for your thoughts anybody else wanna chime in?

 

[tikitoker]

don't worry about P def. It most certainly not. You would have very large dead patches and they would start out as a bluish blotch on the leaf eventually the whole leaf dies and falls of or can be pulled off very easily.

I may or may not have stole something you said in another post to use as a signature till I can think of something better.
( "The term "watering" or seedling should really be called "dampening".) hope you don't mind.

I've always thought that was a moly problem he was having, but you know some growers who have been in the field too long and won't take any sort of hint or even entertain the idea that you might know more than your ABC's.I've always thought that it was a moly problem. In fact I even said something to him about it a few time's. He's like the old grower who's spent so much time in the feild getting high he forgot to plant the seeds. But seriously I told him I thought thats what it was but you know some growers have been doing it for so long you can't tell them anything they don't already know. Nothing again you tiki but I still would love just 1 more opinion from another grower

nah man your good were a community.

I just thought that it was possibly the best worded piece of advice I've seen on riu all night, just wanted to make sure I wasn't the only one who sees it!

 

[tkowitha123]

Any other people care to comment on this???

i'd like to hear about your daily/nightly temperatures and ventilation setup
and also that nectar stuff is saying you want to pH up it with a ph up that includes calcium (they have a special ph up they offer that most likely balances the nutrient) reading up on this nutrient they purposely do a low ph so that the microbes are "put to sleep" without using other special processes, and thus the need for a pH up. The low NPK value they say is because a high calcium diet.http://oregonsonly.com/olympus-up seems like alls it is is dolomite lime with water?

If i were you i'd check out the ROLS thread and not spend money on this seemingly expensive nutrient line. I hear nothing but bad things about "put to sleep" microbes and that you aren't reaping the benifits you could be getting if you did a soil food web type grow with recyclable soil. You can learn how to do all this expensive stuff and not buy into those nutes; but I'm not saying that nutrient lineup won't work at all, just saying you may be paying too much if money's an issue and you have time to do your own organics
i dont really know how this lineup is supposed to be used, and if your "x-caretaker" used the same stuff you do, you could be leaving something out
you could research it http://oregonsonly.com/evolution-of-a-product-line
or do a side-by-side with something foolproof like potting soil that is buffered with lime and something like dyna gro foliage pro, or an a+b nutrient

 

[Cascadian]

I would take tikitoker's advice. After looking again, it does resemble it the most. Moly is a rare deficiency, which is the reason I wasn't comfortable having more conviction about it.

I will add that a P deficiency does not always start with blotches though it usually does. Here is a pic of a P deficiency that is relatively uniform.

Hey thanks for the extra comments guys I really appreciate it, no my old caretaker didn't use this line of nutrients (nectar for the gods). He use'd alot of teas, mixed with this and that, mostly chemical ferts...That being said he was the kinda guy that believed money solved everything always buy new soil, always try the new pound adding cures and snake oil remedy's, or at least thats what I gathered never really saw much of his setup.Far as I could tell there was no method to my x-caretakers madness,although I'm sure he had some help,I think it was another patient of his who actually had the green thumb of that operation. but since this plant has came into my hands I've not noticed the deficiency's reappear yet granted it just got switched into flower about 2 weeks ago so I'll keep y'all posted.

Thanks for the help!

 

[tkowitha123]

Oh btw my money is still on that being a moly defiency.

 

[tkowitha123]

figured I would update some pic's of the molybdnum issue's I was having about 4 weeks ago before I changed to 12/12. These are pictures of the same plant pictured in the previous posts just 3-4 weeks into bud now vs. last pics were last few days of veg.

 

[tkowitha123]

i'd like to hear about your daily/nightly temperatures and ventilation setup

Well the daytime stays between 77F-81F the nighttime sits around 64-70 I have 3 10 in drum fans for circulation and a 6 in' clip on fan oscillating, I have a 4 in 170cfm exhaust fan venting outside with a 70 cfm intake fan pulling air from the hallway closet. I closely monitor my ph with this nute line and try to run it exactly as directed.

 

[tkowitha123]

Does anybody know an organic nutrient that's high in molybdenum?? I'd like to stick organic but I'm not sure what I should add to compensate for a moly def any help or ideas?

 

[tkowitha123]

It seems to have slighly progressed not as bad as the previous grower had the defiency but its still there/ heres some more pics as of tomorrow they are in week 5 of flower.
