Ok, so I am having a CA defieciecy on 2 out of 11 of my flowering beauties...

Does anyone have any experience with CA def's? Does anyone know how long the d. lime will take to absorb into the plant thru its roots, and hopefully counteract, or at least end the spotting? C'mon... I know SOMEONE out there knows about this...

119 views, and NOONE has any input on this yet??? Unbelievable... Vets, r u out there?

179 views, and still no hits at all... Someone, please tell me something about how long they think it will take my dolomitic lime/water feeding in my 5-gallon bucket of self-mixed organic medium to stop, or even reverse the brown spots from this CA def on two of my ladies halfway thru flowering... I beg of you...

Hell, I'll take a shot.

Since it's only on 2 of 11 plants, I'd say it's the strain of the weed.
It's only on some of the fan leaves, not all the fan leaves, right? And otherwise the plant is healthy?
Don't several varieties, suck the life out of the fan leaves while flowering?

If the overall heath of the plant is good, and it's still deveoping, I wouldn't worry about it.
But that's just me.

Luck.

Man, thanks... Yes, other than a few fans towards the top that are spotted with the telltale CA def brown spots, they r sticky, and dank, and healthy as hell... One of them, the ChemDog cross I bred, is the only one with those genetics in there, so it COULD be that strain, but the other one is one I have grown for a long time, and backcrossed a bunch for stability, is a Master Kush(which is a hybrid I bred as well), of which, there are two more, just alike, same strain from same seed stock, and they r just as knarley and awesome as they can be, but no spots on them or the Panama Red, Sweet Island Skunk(also a self bred hybrid), or Acupolto Diamond's(again, a self bred hybrid) that I'm also growing now... Overall, itz like a 9 out of a possible 10 as far as health and good development goes in the garden, but those two had me a lil worried... I did go ahead and put some dolomitic lime and water through the two showing the spots, so this SHOULD at lleast stop whatz going on, with the CA and MG that the lime has in it, and being that I gave it in a tea, of sorts, I'm hoping that it can reach the roots quicker, and get into the necessary parts of the plants to give them what they are apparently crying out for... +rep to u man... Thank you for being the one in 200 that would give it a shot!

Yes, to YOUR question... Usually the leaves that r sucked of "life" are the lower, bigger fan leaves which have been depleted of N during flowering, to keep up with the changes in ares of production, i.e. the flowers and leaves in and around them... I suppose my soil was a lil' weak, being the second grow with the same soil. I often have various, small issues when I use my soil too long... Im definately going to be replacing my soil on my next crop, which is germinating as we post... I have some awesome new soil recipes I can't wait to try out!

Allright, I have the telltale brown spotting on some of the fan leaves ONLY on two out of eleven 4-5 week flowering beauties, so I gave them a proportionate mix of pulverized natural dolomitic lime yesterday... I haven't ever had a CA deficiency before, and am hoping to get some of the veterans to tell me if my problem should go away within about a week, as it is slow-acting, and will it adversly affect my final product, and it was only showing on mabye five or six fan leaves before the lime was applied via a tea, is it to little, too late? My other 9 plants r thriving, and I havent given any of them anything different than I have given the others... One of the deficient ones is a ChemDog hybrid I bred last grow, and another is a Master Kush hybrid I also bred last grow, and the other two M.K.'s r looking magnificient, but the ChemDog mix is my only one... Just wondering... I believe I diagnosed it properly. I know pics would help, but I KNOW, beyond a shadow of a doubt, that the pH is ok, and it is because of a CA def, so I took the textbook advice, and applied the dol lime in distilled water, not as a foliar spray, because as stated it IS in week 4-5 of flowering, and I'd hate to get that crap all up in my flowers... But, can anyone give me any reassurance that my two girls will pull through, so long as what I stated is indeed the case?-which I firmly believe it is... Any advice, or help would be greatly appreciated... +rep will be a given... Thank you RIU community... And I know Deficiency is misspelled in the Thread title, to whomever might want to point that out... Fast-typing, combined with nervousness about a couple plants, coupled with being stoned tends to lead to misspelled words every now and then...

Sup man... I am not a veteran but I will offer my input... I used a top-dress of dolomitic lime to treat what I thought was a cal deficiency on my first grow, and I have to say it will take a while to effect. Lime is a rock so it doesn't actually dissolve into the water, it just suspends in it if you put it in the water. what I did was, first I poked a bunch of holes in the top of the surface with a small skewer... then I actually put about 2 tbsp per gal. right on the top of the soil, and watered over it, letting it run into the holes as much as possible. This worked pretty good to get it in there, but if there's one thing I learned from that it's that I was better off buffering up front than trying to mix it in after. If you get a Cal/Mag supplement it is actually a liquid cal so it will work MUCH faster. My plants did improve but never fully recovered, probably because I was dealing with a combination of things. I think it helped, but didn't solve everything.. I think I was fighting N deficiency and/or nute lockout as well.

You can be pretty aggressive with dolomitic... 2 tbsp per gallon of soil sounded like a lot to me, but it is what was recommended to me at the time from several sources.

And yeah I think you will pull through if it is the only problem... expect at least a 2 week turn around though, unless you go get some liquid Cal/Mag. Liquid Cal/Mag works right away, from what I understand. I didn't bother, but only because I didn't want to wait for mail order and don't have a convenient place to grab it at.

How much lime did you add per plant, and what size are the planters? This is soil right?

Normally I don't think it shows a cal deficiency when sucking out the life from the leaves... just a natural N deficiency that goes yellow then orange and red... but not in a spotty pattern.

And while the plants may still look healthy now, there's no long term guarantee there...

Haha, flattered that you hunted me out for help... funny thing is, I'm not a vet, but calcium deficiency was one of the things i had to deal with on my first grow. What I learned was that FoxFarm Ocean Forest blend has enough calcium for about 6 weeks by default... I now add 2 tbsp per gal of medium when mixing at the beginning.

Yeah, I wasn't getting much action from many others, so I had to hunt one of my buds down on this! lol! I put in a third of a cup in a gallon of water, hoping to kindof "over-do" it, as the dol. lime shouldn't burn, either way... Then, I watered on top of all that... Of course, the first mixed gallon, was split between the two plants with the spots happennin... Everything prettty much looks just fine, though... The buds r already so sticky in the 5th week, that my fingers stick together after I lightly "pinch" a flower for a smell... So, I'm sure I'm not too far off. Itz just a lil weird, because I stay on top of my pH, and haven't ever had a CA def before, out of probably 20+ successsful indoor grows... Just had a few "norml" Nitrogen, and the occaisional Phosphorus defs, that r easily, and quickly remedied, with guano teas of whichever macro nute it is... Thanks for the input... So, +rep to you , my friend... Ya, Idk if I'll be able to get ahold of any of the liquid CA, but I'm sure that in the next week or so, with what I gave them, and with each watering, every other day, or so, I'll see new, healthy, fresh growth, and no more spots... Or at least I'm perdy sure... And u got yer rep on here somehow, so Im perdy sure u know yer shit, and from our conversations, I gather as much also... I'm sure the green bars didn't appear under yer ranking for nothing! lol! Mabye one day, I'll have half as many...
