Well I thought I needed CalMag

[KaliRush]

From pics online, I thought I had a calcium deficiency. Added Calmag and it's much worse tonight. These pics are from before.

White Russian
43 days into flower
FFOF Soil
FF Nute; 1/2tbl Big Bloom, 1tsp Tiger Bloom, 1/4tsp Cha Ching

I have had similar issues with CalMag...the best thing I came up with was that it is causing a phosphorus lock out...you are almost done though, so...should be ok...

 

[Core]

you could easly do whole run without feeding the FFOF...that shit is specially designed for that....

dose your tiger bloom rattle when ya shake it up before use ???? if so its gone bad organic material has died and has turned solid. them pics look just like when my tiger bloom went bad

FF grow big has a shelf life of 2 yrs when kept in optimal settings dark and cool envroment
FF tiger bloom has same 2 yr shelf life
big bloom has 3 yr shelf life

whats your waters PH when feeding the plants

 

[KaliRush]

Always within 6.5 to 6.7

All my nutes are less than 8 months old (actually I'm not sure how long they were on the shelf though before I bought them)

I guess since I'm getting close to the final flush, maybe just let it go?

I'm using the full Botanicare line and I've found that for me Cal Mag is best used during veg. Seems to help create strong stem structure.

 

[Maj.PotHead]

my last bottle of grow big and tiger bloom went bad shortly after buying them off shelf just something to think about

 

[merkaba]

Yeah, my buddy just said he realized CalMag was almost bad once in bloom....just his 2cents

 

[ridgedogs]

I agree. I don't use it at all in bloom.

 

[MarquisBlack]

Ya, it's got nitrogen, plus the CalMag itself makes buds taste TERRIBLE.

 

[phreakerrot]

looks like nutrient blockage to me.. flush the soil

 

[jammie]

yeh- whose bright ass idea was that to put nitro in cal mag. it seems ya have to read the labels. dark energy also has 2% nitro. no wonder my sativas where showing leaf canoeing.

Be prepared to take those to day 70-75 all 4 of mine currently are 56 and no where near finished. Just something to think about GL on fixing your problem man!

MagiCal has the 2% nitrogen added too. lol, it's tough to supplement the missing calcium and magnesium from the FF line if I have to worry about nitrogen. Would flushing a bit after feeding release some of the nitrogen and leave the other two?

Hmm it looks like you could have been over feeding the plants. I use Fox Farm Ocean Forest soil and the 3 part GH flora nutrient line (micro, grow and bloom) and I only feed my plants once they're at 2 weeks flower and at 5 weeks flower. As Core said, a person could very easily go without feeding their plants using fox farms ocean forest soil. I personally like to use just a little.
I ain't sure if your using it or not, but blackstrap molasses works great too for cannabis gardens. I'm pretty sure it has some stuff CalMag has in it too. Plus I hear that molasses is something that can help the plants take in nutrients more efficiently. 1 tsp/gallon of water will do the trick (plants don't need the molasses very often either).
peace

I had to leach my FFOF after screwing up the pH, so I feed on a pretty regular basis with the FF line. I also have been flushing when I plant to minimize the chances of burning youngins.

I see alot of folks saying not to use calmag in flower w/ FFOF. What if you are using RO water though? I hate the nitro in it, yes, molasses is good for some micros. Earth Juice makes something called "Hi Brix" special plant molasses. Blackstrap works too. Cheaper.

Any opinions on the RO water, I always thought you needed to use calmag w/ RO period. Last run I cut it out at 5 weeks into flower. Is it possible to go w/out all the way in FFOF, I wouldn't think so? How about it?
