Do all Cal deficiencies show signs?

[Antrim]

I was wondering if I could have a calcium deficiency without the leaves showing any physical signs. I just harvested my first organic trial and I am not impressed with the yield I got. I use RO water so I supplement Cal and Mag with 2mL of GO Cal/Mag+ per 5 gallons. I know this is a very light amount but I figured I could add more if the signs ever popped up. Needless to say, they never did. After reading about the importance of Cal for cell division I thought my low dose of Cal/Mag could be responsible for my less than stellar results. I know there are a lot of factors that come into play here so I'm trying to check thing off the list to become a better gardener. Since it never showed signs of deficiency should I assume my Cal is good and move on?

Avoid RO water for this very reason, ripping the Cal out of a most crucial component as water, removes other irons and minerals too, most plants do require a top off of cal/mag or Epsom salts 3/4 thru to harvest as fast growing plants soon deplete available reserves

I'd be monitoring my water closely thru out my grow, more so in late summer, as you never know where the local government worker get that water from, do a ph test, of the water every week, and chart it...for peace of mind

Unfortunately I'm stuck with RO. My tap water has chloromine so I bought an RO system and some Cal/Mag. I'm just not sure I'm adding enough. I know it sounds like a stupid question but I thought there might be a chance that it's too much to show deficiency but not enough for the plant to produce properly. I didn't ammend my soil very heavy so it's probably a lack of all the good stuff rather than just Cal. The plant was a Critical+ 2.0 which is supposed to be a heavy yielder but I only pulled about 2oz off of a 5ft tall plant. For my first run I wasn't expecting much. Just trying to figure out where to start improving.

seems i've heard peeps say 5ml per gallon
the answer's here somewhere
but do you need it in organic soil?

 

[Antrim]

Yeah. I amended pretty light. No dolomite or Epsom. I'm sorta surprised she didn't show a Cal def.

If its not showing its not the problem imo. It was a different factor imo. Most ur nutrient mixes and soil mixes for this industry have plenty of each nutrient u need.

What is in your base soil? Almost all bag soil has too much K and not near enough Ca

if you're doing organic then why are you pouring in bottles of calmag instead of just adding lime to the soil? takes 2 weeks to start breaking down. you add some to the mix. then in week 2 of flower you top dress a little bit more. should take you all the way through the end.

Chloromine aint no thing... Add some tap water to your RO and forget about cal/mag. Gypsum is great for calcium, since it doesn't have Magnesium in it.
Dank Frank, has an excellent liming recipe that calls for Dolomite,gypsum and oyster shell in the Stank Bros section.

This plant is on nothing but water, organic soil

What kind of lighting do you use?

I have a 1000w Hortilux EYE Blue. Won't the chloromine hurt the microbial life?

It was bad planning on my part. I'm a hands on learner. I figured if I just popped some seeds quick I'd figure it out as I went along. I have done a lot of reading but I could read something a hundred times and not retain it but if I just get my hands dirty and do it once, I'll never forget. I've added dolomite and Epsom to my SS now so I don't think it will be a problem anymore. You think I could stop adding CalMag to my water even though it's RO?

I'm just growing for myself so messing up isn't that big of a deal. I should be getting a camera soon. When I do I'll start a journal, which should make getting help a little easier. Thanks for all your help folks! We'll see how this next one turns out.

Do they! check this ugly bitch out!

And that cut used to be this

 

[Antrim]

I forgot to tell you. This plant stretched like crazy! It was about 18in when I put her into 12/12. Within 3 weeks she was about 5ft tall! I harvested her a couple days earlier than I wanted just cause she was so unruly. All of her branches were limp like cooked spaghetti. Pain in the ass to trim.

 

[Antrim]

LyryC- What caused all that?

 

[stihgnobevoli]

all those pics show signs of calcium lyryc as well as other things. If i had to take a wild guess i'd say pH was waaay off. for a long while at that.

@Antrim in regards to your comments on RO and Calmag. If you're going organic you def don't want RO water. the water in the tap is fine, maybe better. it already has nutrients in it. different nutrients depending on where you live. there should be a water quality report you get once a year. or by request. when i lived in the midwest i never really needed to add much magnesium because there's lots of limestone in the ground there.

but if you use lime in the soil/mix then you shouldn't really need calmag. maybe keep the bottle for emergencies. but between epsom salt and lime and tap water. you should be covered/

Ive also seen broadmites do damage similar to the photos above. leaf clawing, mosaic spotting, leaf side hooking as you can distinctly see in the photos above. If you see your buds getting shaved like a pine cone and losing potency/smell/yield then its def broads.

Like mirac said above if you dont see signs probably not a calcium def.... other factors probably like crap genetics,genes have a lot to do with it if everything else was good and the lady was looking healthy def just not a keeper. Everyone has had poor/low end genetics at one time or another you take a chance everytime you get a new clone. Makes you appreciate the keepers once you find them Then you can add it to your stable list of genetics and keep it around for as long as youd like.

Dude I reused medium, and it was wayyyy to hot. IT had 2.2 EC coming out lol. I use all new coco everytime now. can't keep up with the reused once or twice mumbo jumbo, fresh and worry free.

Plus that plant is a Calcium whore.

So, just to get this straight, you guys are saying it's ok to use tap water with chloromine in it? Everything I've read said that chloromine is a HUGE no-no when dealing with organic soil. My tap definately has chloromine. I checked it out. Even when I was running hydro in chlorine tap water I would bubble the "Chlorine" out for 24hrs. I've read that "Chloromine" cannot be aerated out and will kill the soil life pretty fast. Is this not true in your experience?

You my friend are correct I got my tap water analysis last year for shits and giggles and I also found that I had Chloromine and like you said that cant be bubbled out. But I also dont just go over to my faucet and use the water straight out the drain. I use a tallboy in your case im sure you could get away with a small boy water filter . It takes crap out of my water has a 2 chambers carbon and filter that I replace every 3-6 months depends on usage love that thing filters are cheap too. So i use "filtered" tap water make sense ? I dont know if other people are doing that but my I can tell you from personal experience that my plants love my filtered tap water its under 150ppm always.Dont need no calmag either. I know I put my nematodes in my filtered tap water and they do fine. I havent done full organic before not my cup of tea so an organic person will chime in soon. I use a dead rez 6/9 with my filtered tap but I know people who make microbe teas with my filtered tap water so I think its good.
