CalMag and Thrive in bloom...

[Weedhound]

Hey Dave,

I was taught to use CalMag at 50% of the total ppm all the way through until I reached the max amount of CalMag recommended on the bottle....which I haven't done yet. By the end of flowering I'm probably at about 500ppm of CM...which ends up being about 5-6ml per gallon. I've always measured it in ppms vs mls which, again, was the way I was taught. I have tons of faith in the guy who taught me to grow so I will stick with that. I use the botanicare line btw so don't know if that makes a difference. Also I recently asked the same people about coco issues and found that they recommend you use less CM for coco applications so perhaps the medium you use makes a difference as well.

i thought the max amt. on the bottle was 5ml...my bottle says 2-5ml per gallon...i go half strength but believe i need to up my dose closer to 4 or 5 instead of the 2.5 ml per gal i regularly use (only during flowering)...most base nutrients solutions (Pro-Gro, Bio-Grow) have small amounts of cal-mag that i was taught was more than enough during veg. growth...but what the hell do i know? :thumbsup:

Yeah I just read the bottle again myself curious...I grow hydro so up to 10ml per gallon and I haven't hit that yet. For soil it says 5ml/gallon but then notice underneath it talks about an "accelerated formula" for soil....10ml/gal.

Also I was taught that if you use tap water it usually will provide enough calcim etc..for your plants. I use the Botanicare line myself and was told that with RO water you really need the cal-mag to supplement...again hydro...fyi...

correct - Reverse-Osmosis units remove calcium and magnesium from the water - adding Cal-Mag or Dolomite Lime to the water replaces both, and will adjust the pH while doing so, so be sure to re-test your pH after any additives :smokin:

[Weedhound]

Frank how much dolomite lime would you add per gallon to correct a calcium def in a dwc system?

Ok; you all have my curiosity with this topic...are you talking Hydroponics or soil growing?

Well I'm in soil and don't use superthrive in bloom, but I do use calmag atm simply because my plants are recovering from a coco experiment gone horribly wrong, lol!

In the future, I don't expect I will need the calmag, as my old soil method included some bone meal and a bit if fish glop mixed in to the soil of the last transplant, and myco-stim to help release it, and I occasionally add either flora micro or algoflash to the feedings... like, once every week or 2.

LOL, one question I didn't even think to ask.....soil or hydro? Good for Zandor! :thumbsup:

exactly what im after SOIL.Im using ro water in soil just now and man is it giving me a sore head i cant seem to get it right so hope some of you can help put me at ease here i cracked the ro hydro with sensi cal mag now its soil giving me major stess.Is it possible to grow trouble free in soil with ro water?Im using sesi cal mag grow and bloom I know in coco and hydro ro water is the best option but im having mad problems getting it right.I presume ( correct me if im wrong please) that my soil has calcium and magnesium already added and my canna nutes already have added cal +mag so unless i know the pecentages of the cal mag in the soil i will never get it right?HELP LOL.My tap water run out at pH 7.2 and ppm 100 and after 24 hours getting defluorinated and airiated it comes down to 80 ppm pH 68 So what my best option people my weight has suffered trying to get this right and for the first time my plants stretched like mad.
what is the benefits of using ro in soil i know the hydro benefits but in soil i cant see that it helps with weight..any help would save me getting stresssed and keeling over with a heart attack.thank peepo.davey the postman
