What could possibly be causing this!?!?

good advice from everyone here but if i were you i really wouldnt mess with it to much, the plant seems to be doin great and loving what your doing so i would mainly stick to whatever it is your doing friend, good luck
 
No, it is because you aren't feeding enough and the plant is trying to grow faster than what nutrients are available to the plant. The plant is basically cannibalizing itself to keep up with growth requirements. If you are adding cal/mag every day, what about other nutes?

this kinda makes sense lol. when i add water to the rez (about 1 gal a day) i add cal mag and grow fert.
 
Yes sir, the ph swings could definitely cause that. Most likely it's what Slanty said. That's why I kind of reiterated my position on feed. I could see problems eventually. Are you flowering your plant?

Try running straight PH'd water overnight, then start her back on at 1.0 EC and see which way the EC goes in 24 hours. Your PH should be easier to control too.
If it rises, drop it down to 0.9 EC. If it drops try upping it to 1.5 EC. I'll bet it's going to be right around those ranges.
Also, you don't want to add CalMag outside of the proper ratios of your feed schedule or you'll lock out other nutes.
So, don't just go adding a bunch of CalMag without keeping it in ratio with your other nutes.

Try that and I think you'll be happy with the results. It won't fix the damaged parts of the leaves, but all new growth will come in right.

Another little tip on PH ing after a res change is to check it and adjust it twice if necessary.
After you add your nutes and get your ph where you want it (5.7-5.8 ) leave the reservoir alone, and check it 3 hours later. It most likely will change as the water and nutes all get settled in (I don't know the scientific term). After you adjust it the second time it will stick. If it doesn't, still leave it for 24 hours before adjusting because PH up/down will both raise your EC and throw you off if you are watching for movements in EC.
One more tip. If you are using hydroton/expanded clay pellets lower your nutrient solution far enough that it does not come into contact with the hydroton.
About a half an inch below should be good. That stuff is notorious for blasting PH if not prepared properly.

keep Updated.

Taviddude you are the motherfucking MAN! lol i really apreciate all the help.

i will be flowering her, im going to clean her rez tomorrow, upfeed her check the EC and find a way to stop this calcium problem. it makes sense that she might be eating it out of the plants because its not readily available to her at the rate she wants.

i will attempt to clone her tomorrow too, i def want to keep this pheno cuz its awesome! ill be taking about 4-5 clones and once i have a healthy rooted clone i can mother then i can flower blue (her nickname lol), so hopefully ill put her to flower within the next 1-2 weeks.

couple questions though,

will me cloning her affect her yield?
is 2 weeks enough for her to recover?
will she grow those branches back?
what part of her should i cut for clones? the branches that connect to the main stem or the branches to connect to those other branches?
i say that because the branches connected to the main stem are THICK, like id feel like it would hurt her if i cut those.... ive never cloned before but i need to preserve her... shes just the best plant ive ever had
 
good advice from everyone here but if i were you i really wouldnt mess with it to much, the plant seems to be doin great and loving what your doing so i would mainly stick to whatever it is your doing friend, good luck

yea shes definitely a keeper, i just want to stop this calcium deficiency that seems to be spreading a little bit!.

thanks for the support man!
 
I'm not a clone expert. I've only cut a few, but they all survived. Look around Youtube and there are a lot of great tutorials on cloning.

Just take a few small clones and it shouldn't hurt the plant very much.

i just bumped her PPM to 700.... im kinda worried, but shes a big girl she should be ok... im going to check if the PPM drops or goes above 700...

if it was too much for her, would her being on that solution for 1 day be enough to burn her?
 
That's quite the jump. I would have went wit 1.0 EC, or 500 ppm. It's always better to err on the side of underfeed. Your plants won't usually show burn in 24 hours unless you REALLY overfeed. Usually the leaves will just claw down showing overfeeding.

One more thing, when talking nutrient solution strength with people online it's good to use EC rather than PPM when possible. EC is universal.
PPM meters are EC meters that use a conversion factor to figure out PPM. The conversion factor changes with manufacturer as does PPM readings.
EC is universal.

What kind of meter do you have?

Peace.

ok i will def keep you guys updated, i did check last night and i saw her PPM was dropped to 580 from 700...

i will start using EC, i have a blue lab PPM pen and does reaidns in 500, 700 PPM conversion and EC. i usually use the 500 conversion factor.

So heres an update:

I fed her 740PPM (1.4-1.5 E.C.) yesterday during her weekly rez change, ph was adjusted to 5.5, this is about 1/2 strength from Technaflora's recipe for success and full strength for CaliMagic which full strength should be about 1100PPM (2.1 E.C.).

today she drank about the same amount and i checked the solution it was: 440PPM (0.8-0.9 EC) thats a pretty big drop! her PH was 7.1!!!!! makes sense since she almost drank half of the nutrients lol...... i feel weird feeeding her more.... so today i just topped up the rez with fresh water and adjusted her ph back to 5.6.

i took 5 clones from her... 4 smaller ones and 1 bigger one (experiment) so i feel she's still a little sad i cut her. i have also been doing some LST and trying her down to make sure the inner shoots get light

what do you recommend now? up her EC until the drop is minimal?

here she is @ 43 Days:

Wow, that plant is HUNGRY! Yeah, keep going up until it doesn't drop so much.
I would use equal ratios of CalMag with your other nutes though. Generally an EC of 0.4 or more of calcium will damage a plant. 500 ppm of cal mag is a LOT. If your plants were deficient they may respond well to it for a few days, but problems may set in after that.

DWC buckets truly are the "best" hydroponics. You can read a plant perfectly, they have constant acces to nutes, water, and oxygen. You can see how you can push a plant to it's genetic potential with DWC.
You can see now just how much food your plants wants, or doesn't want. Once you get it dialed in, and hit that sweet spot where the PH levels out, and the EC only drops minimally you can see how that will bring the plant to a new level, eh?

amen to that!
 
Any updates Man?
yes actually. so she's been drinking more everyday... and ive been tryinh to keep her EC stable at like 1.0 (500PPM) every morning still she drops to like .5-.6 EC...i did notice that her top fan leaves have some weird brown blotches on the edges of the leaf and some even yellowish tips. (looks like nute burn?) i will post some pics later when i get home......but even when her EC was 1.4 she drank more than half on the first day so idk why that would be nute burn but i havent done anything differently besides that....
 
Any updates Man?
one big thing i have also noticed is her leaves are way way perkier than normal... she seems really happy!now im even more confused tho.... does she want more food than 1.4 EC? she eats and eats but then she gets this weird big brown spots... so im even more CONFUSED!!

If she dropped from 700 to 440 ppm, then yes. Moar!

My current soilless babies are happy with a 600ppm (EC about .85) feeding ... the runoff is just over that. That's from a Nutra Dip that has the EC 1 = 700ppm convention. But they are young plants in veg. I will use my TDS meter to follow their appetites. cn

MOAR MOAR! haha i guess i should try full strength wich is about 2-2.1 EC? or should i gradually bump her up? i want to flower her no later than 2 weeks from now.... ive had some clones rooting since saturday so as soon as i get roots on my clones im going to flower her i dont want her to grow too much that she'd become untamable lol

I'd bump her up in stages ... about .2 EC at a go. And I still think "a little light" is safer than "a little heavy". But the ppm trend is a good measure imo. cn
