    How to properly use cal/mag?

    I have Hardwater. I do not have any water softeners in place but somehow it was still giving me problems.I caught it in time with some help from 420 support,and flushed with distilled.
    My plan now is to use distilled water on water days with cal/mag from here on out. But on nute days I was going to use the hardwater because I use hardwater micro. Do I add cal/mag to that also??
    Or do I used distilled water on nute days as well? And if I should use distilled on nute day will still using the hardwater micro have any adverse effects??
    Hardwater SUCKS!
    Also is cal/mag something you use all the time or just when needed??

    I don't think it will hurt to mix with nutes but I use calmag even though I no longer have mg/c deficiencies. I have a gallon mixed with calmag and tap water set out of 24-48 hrs along with some vinegar to control my ph. Hasn't hurt my plants one bit. I also give in a foliar spray mixed with nutes.

    I will endeavor to answer your questions..

    I am curious how you determined the water was hard and bad? Do you know the ppm and alkalinity of your water?

    Working with DI or RO water can require the addition of calcium and magnesium due to the fact it has been removed from the water. It is a nutrient set needed by most plants. To add it back is the normal procedure. Hard water will already have ample amounts of these minerals.

    Your hard water nutes are designed to work with hard water, which means it lacks what the water is abundant in. As I am unfamiliar with your nutes I can not comment on it any further.

    Given what you have at hand, I would suggest water with cal/mag and RO water, then feed with hard water and nutes when it is appropriate.

    like smokz said, hardwater micro is missing most, if not all of its cal, and mag.

    if i were you, i would use cal mag every time you feed.

    lots of the time i notice even the normal micro's lack in the ca and mag department and i need to use some anyways. (i use RO) so. start adding it at reccomended str, and see where it goes from there.

    if its continues to show a def, add more, and if all is good, try lowering the amount you use slowly until you get to about half recommended.

    if at any point it starts to show a ca or mag def, raise it back up a little, and leave it there youre whole grow.

    Re: How to properly use cal/mag?

    Thanks for the replies as always fellas. To be honest I dont even know for sure but I think I have hardwater. Shit maybe I dont and just the fact that I am using micro hardwater is giving me the difficiency. I have well water and see like dark(blackish) marks in the toilet well behind the bowl. My nieghbor has softeners and I dont so I just figured I do. Something is causing fan leaves to turn brown in blotches and the tips are curling up and drying out. But since the flush they seem to be good.
    Put it this way , I am in the third week of flower and NEED TO KNOW how the best way to finish this safely. I have to much time invested at this point. Even if I buy distilled here on out for water and nute days, I still have regular micro for it.
    Let me give you guys my schedual so maybe you can see if I am doing something wrong:
    I use FF OF soil(thats it nothing else mixed in)
    GH floragrow,floramicro(hard), and florabloom
    also floralicious plus,florablend,floranectar,etc. Pretty much go with the gh expert(drain to waste) schedual but keep everything on the low side so I dont over do things.
    I also use fox farm solubles (open sesame,beastie,and cha ching) but on the low side as well like for example it will say 1/4 to 1/2 teaspoon and I will go 1/4.
    The only other things I use are a Great White root treatment(good bacterias and microbs) and hydrozyme(3 to 4 ml per gal., also on the low side of the recomendation.
    I had the same prob. last time, the fan leaves dried out and fell of throughout flowering and I still did pretty good, if I could figure this out I could really bring it to the next level.

    Any ideas?

    One more thing also, I would like to do a root treatment again since I flushed but is there any setbacks doing that in flower?

    Re: How to properly use cal/mag?

    One other thing, the reason why I flushed is because something(thinking the well water)was causing the ph in my soil to go way down. I took a simple soil test and was a 5 also runoff was coming out in the 4's at first. After the flush I got it in the 6's. So I think we are on the way back but need to know the least risky way to finish up.
    I know I need a PPM and a real soil Ph tester, but they are so $ and I have invested in so much other stuff. I want to eventually get them just cant right this moment.

    Re: How to properly use cal/mag?

    it sounds to me like you are getting mag def come flower.

    i would start adding some magnesium to it. a cheap way to do so, is epsom salt (from any drug store) mix in a bit into your water. little goes a long way.

    or you can get a product like calmag, or calmax. its about $10-12 a liter.

    Do you think I can still use my water on nute days or should I use distilled from here on out for everything?? Does it sound to you like it is hardwater? How about micro or hardwater micro, which do you think I should use?

    i have no experience with hardwater micro. and personally.. i would use RO water all the time.

    if it were me in your situation, i would use the normal micro, and use RO water from here on in. then add calmax at recommended str.

    you can just control it better, and know exactly what you're giving her. which IMO is best.

    Holy shit! ThAt made me think! It is possible that I really don't have hardwater after all .
    Let me ask u guys this: If I don't have hard water and use micro hardwater, cOuld the lack of( whatever it is that the micro hardwater lacks) cause a difficiency like I had?
    I think like nibec said until I find out what is up with my water I am going with DI water with reg. micro and cal/mag fr here on out.

    Do you guys think that 4-5 days is enough for a 4gal bucket to dry out after a flush?

    Re: How to properly use cal/mag?

    It is quite possible yes...

    RO or DI with cal/mag will put you in a consistent water source. That is a good thing. One less thing to worry about till you can determine what your tap water is. It may be fine, just need to know what you have.

    That will depend on environmental conditions. I test by weight. Or stick something into the soil and see what sticks to it. Like the way Mom tested a cake to see if it were done inside. Can you stick your finger is a bottom hole and tell anything?

    If you have good drainage and reasonable humidity it could be dry enough.

    Re: How to properly use cal/mag?

    I would pick up a good ppm meter if I was you. That investment will answer most of the questions you have. Or, like nibec said, stick with R.O. water from now on. You will have to get regular nutrients though.

    When I started growing I didn't think I needed a $80 ph meter, or a $100 ppm meter. I easily spent way over $180 on the extra electricity, time, and wrong supplements trying to fix a problem I couldn't even diagnose correctly. These are tools you need to grow successfully.
