Calcium def or?

Rutigito · Oct 15, 2012

I'm just a couple weeks from harvest and these kinda problems have been showing up lately. Any ideas? Should I just ignore them cause it's so close to done?
In addition I should add that my setup isn't hifi at all and I'm using generic nutes (for all flowering plants says the bottle).
The plant has dropped almost all of it's big fans leaves by now.

More details please. Everyting you can think of to describe the plants environment. That's not natural and if she's lost the fans, it'll move to the medium sized leaves next. As you can see.

Exactly how close till harvest? You cant let that ride very much longer.

Looks like a disease.

Rutigito · Oct 15, 2012

Well I'd say it's about two weeks until ready just by looking at it, It's been in flowering stage for about 6-7 weeks now.
Well here's the environment:
- Temperature: 77 F (25 C)
- Indoor growing with regular sterile potting soil ph 6,5 (don't know what is the ph now)
- Lights: 130 watts cfl's + led plate (12/12 of course, dark time uninterrupted)
- Nutes: Generic mix for flowering plants
- Water: Tap water (clean here)
- Ventilation: Fans not directly pointed + ok natural circulation of the room
- Strain: It's a mystery seed but pretty likely skunk special or super lemon haze

The plant had some pest problems at one point but I got rid of them.

What pests, as this could help the veterans in diagnosis. Curious cause I am on day 19 and battling fungus gnats

I had some gnats in one of my plants recently -- I hit them with crushed mosquito dunks and they were gone. I hard ordered some gnatrol (same thing) but I never got the chance to use it.

Rutigito · Oct 15, 2012

I'm not a 100 % sure actually what pests...I never saw them though I tried to look for them, I Just saw that something was eating my leaves for sure

Maybe mites or something really small? The leaves started having small holes in them, like maybe same size as you would make with a needle.

Rutigito · Oct 16, 2012

I could also add for the environment that the plant has lots of leaves like pic 1 and maybe 3-4 as bad as pic 2 at the moment. The damaged ones are mostly in the middle area, lower leaves are good (so far) and the top looks good as well (aka. the main cola). The sick fan leaves turned kinda yellow before they dropped, they looked different than the medium leaf in pic 2.

I would say cal/mag. Especially as your using generic flowering nutrients. I find in the last 4 weeks of flowering its really needed.

Have you checked the nutrient analysis breakdown on the bottle?

scroglodyte · Oct 16, 2012

do you have mites? sorta looks it. check underside of leaves for little brown dots..........that move. and some whole-plant pics, plz.

Yeah it's 10-5-8, quite shit i presume? But still I'm pretty satisfied with it, the buds look really frosty and the smell is heavenly

Its the micro-nutrients you want the details of... Mg/Ca %'s

I'm not saying you need "AN big dick boost" or any such overpriced rubbish, just that most nutrients just don't live up to the plants flowering requirements in the Ca/Mg department so may be worth looking into.

I tried to look for them but couldn't see any movement what so ever...u can see the mites with the naked eye? I'll post some pics when I have more time. But the plant looks pretty sad already, or actually the plant looks like it's doing the harvest-trimming for me

Since the bigger leaves have fallen it's like a 2 feet stick with buds and small leaves

Yes you can spot them with the eye, creepy little fuckers!

Also your nutrients are really high on nitrogen for a flowering nutrient.

Oh right

0,01% B, 0,02% Cu, 0,07% Fe, 0,05% Mn, 0,008% Mo and 0,02% Zn
So there isn't any Mg or Ca in the nutes

Any home remedies how to get some in there or should I just go browse through the gardening stores for some other nutes etc

batf1nk · Oct 16, 2012

There ya go

No cal/mag in them at all, or under the required amount for them to have to list it (most probable) :/

I would say screw the cheap ass fixes and pickup some cal/mag... are you in hydro or soil sorry I forgot.

Rutigito · Oct 16, 2012

Yea I guess I should do that... Didn't take that into consideration at all when I bought the nutes, live and learn...

I use potting soil

Indeed, one for the experience bank eh.

You can add dolomite lime into your soil mix, it stabilises pH and has good Ca/Mg... other things will help with micronutrients like azomite and other rock minerals.

If you want more control over it grab some cal/mag and use that.

Its simply an over abundance of crispy curly brown. Try and cut it in half from here on out.

Calcium def or?
