CalMag is a product. If you have a mineral deficiency, that'll do ya.

I snagged a bottle of Calmag+ from GH. Works well and has a few more goodies in it. My only complaint is the bottle sucks. It's like a mini antifreeze container. If you're not using a dropper and try to pour it you'll lose 10 more than you use. Small problem but its irritating when you buy something. Go to use it. Crap spills out all over. Then you have to run out again to grab a dropper for next time. Otherwise its a solid product.

Good old water - flush for at least 1 week , 2xs' container size in that week. you are either you are feed to strong amounts of nutrients when feeding or feed to many times feed 2 out of three days - good rule of thumb (learn something new each grow and each grow is better than the last !!)

Problem was PH. I always used the little test strips and never got a clear reading. I bought a bluelab meter today. My tap PH is around 8.2, after I add H&G nutes it brings it down to around 6.2. I was always adding around 5 ml of ph up, but I added how much I usually use and ph was still at 6.3. Adjusted to 6.7 and all should improve. Thanks everyone for your help

Yep keep pHing that water to 6.7 and you'll be alright. I wanted to let you know about the pH because i made that same mistake, thinking i had a calmag issue. It took me months to figure it out, an entire grow almost and 1 ruined plant.
You might not notice a turn around right away, hell the affected leaves might never reverse, but the new growth should look healthy and thats how you know you did your job correctly.
Good luck man!

Well at first I thought they just needed to be repotted, because it seemed like they were outgrowing the 7 gallons. A bunch of the roots were showing on the top. I repotted one into a 15 and 3 into 10 gallons, theyre under 2x 1000 watts and are looking fantastic besides the Issues. A lot of leaves are drying up. A lot of yellowing on the tops. Basically all showing signs of K and Ca deficiencies. And yeah I am like 99 Percent sure it was my ph. I did the exact same thing I usually do today except using a bluelab meter, and my ph is normally 6.3 when I water. They couldnt take it in.

Flushing of any kind does more harm then good! If an overage situation is happening. Simply use plain pH'ed water and no nute's for 5-7 days and restart.
This applies here too.

Hydrated lime is way to concentrated/fast acting for use in our gardens by those who don't know how to employ it. It should not be used in soil building......Most growing books of any quality - say you should avoid Hydrated Lime.

If you're in soil, you should be using an insoluble form of calcium, like limestone, bonemeal, or gypsum. It should be built right into the soil.
For hydro, calcium nitrate is the only way to go. Cal-mag+ is just diluted calcium nitrate, magnesium nitrate, and iron chelates. If you have a calcium deficiency in hydro, you're probably not using enough of the "micro" bottle whose main ingredients are calcium nitrate and Iron DTPA (in just about every hydro nutes brand). If you have magnesium deficiency, magnesium sulfate makes more sense to use than cal-mag+.
Cal-mag products in general are just a rip-off.

I hear this often but if I don't use Cal-Mag my plants are totally fucked....with Cal-Mag they are nice and green
I tried reduce the amount of Cal-Mag I use in half, and got nailed with a deficiency.
I understand there are cheaper alternatives such as Epson salts but a bottle of Cal-Mag will last me years...not a big cost to keep my plants healthy
So in my situation.....Cal-Mag is NOT a rip off

For the price of a a gallon of cal-mag+, you could get a 50lb bag of calcium nitrate (that's 30 bucks), which is the main ingredient in cal-mag+. Like PK boosters, it's just more overlapping nutrients you don't need. You could easily just use more of the GH "micro" bottle if you're lacking calcium, as the main ingredient in that is also calcium nitrate.
To me, that has rip-off written all over it.

yeah right....if one quart of CAL-MAG ($10) has already lasted over 2 years and still has 1/3 left over, just how long would a 50 LBS bag last me....like more years than I have left in this world
I guess you didn't read what I said....without it I have disastrous results...so don't tell me it's a rip off
if you don't need it good for you but my tap water is so pure that I need it...end of story

I remember UB PMing (or maybe in a posting) me about not wasting my breath sometimes.....Hell, I say use a Ca/Mg product to many because that's how they want to handle the problem.....
Me, I just build my soil, water, harvest, cure......Sometimes the details of just how I do that, or what I use get me blasted....I don't like to post exactly what I use and how much.....It works,,,,the blood, feather meal folks like that stuff, I don't. I don't use prepacked organic nutrient "blends" either (5-5-5 or "bulb" foods). I simply add more of what their made of......I just don't like getting hammered for what someone else believes/does as being gospel....
@ISK ,, Dude, church was only trying to help. He gave an alternative that works and ,,, for some, is a cheaper better choice...That bag of calcium nitrate...will last longer and thus be cheaper in the L-O-N-G run.....it's only a point. K?
I understand what you do.
If that's what works for you.....
Do it!
Peace on
