    Select your nutrient range and water hardness and go. I use 2/3rds of recommended dose. (ish)

    So I have a question on this chart, in the custom water setting I clicked on Hannah PPM, but what value do I enter in the water hardness ?
    Here is a rundown on my tap water. I presume it would be the 125 but I just want to be correct about this . Thank you guys for your help . 20170912_153913.png

    Thank you GR, and then how does the two PPM columns at the far right come in to play ?

    Are you guys generally happy, yield wise, using these products ?

    The 1st is the EC or PPM of the nute solution, the 2nd is the total EC nute solution plus your starting EC or PPM.

    You can back off the A&B, but I keep the rest of the numbers the same.
    Yes I like their product.

    GR

    Look at my sig, and follow it, you will see my yield.

    I've had good luck with 1/2 the light feeding schedule + calmag.

    is that 200pm of each? so would be total of 400ppm? and 800ppm in flower?

    I'm sure this has been hammered on about in a bunch of replies over the last 130 pages. but i am running pure coco, i was thinking about mixing in some peat, Im running in dutch buckets with the bottom inch or 2 of the bucket filled with clay pebbles. what ratio has been found to do the best job, or would something other then peat do a better job. I have a bunch of coco on hand.

    I run straight coco, tried other mixes, coco is the best!

    How often do you guys flush your coco and how do you go about it? I have read all different types of responses on this and I'm not sure what to do. My grow has been AWESOME (thanks to the good info here!)since I switched to coco and I am just reaching the end of week 1 flower and the scrog is filllled out. Plants look extremely healthy and I am pretty pumped. I have been feeding daily and sometimes twice a day in 2 gal pots. I am going to get a chiller today so I can use the res in my room (under my table) and automate the feedings without worrying about res temp. I had a the smallest possible amount of tip burn when I was feeding around 650 ppm and have been mint since I went down to 600.

    when I feed I get some runoff and probably could use a little more but I fill a 5 gal bucket to the brim and just put my pump right in the bucket to feed through drip stakes. I am at the point where they're drinking more so the 5 gal bucket isn't producing enough runoff for me to be comfortable and that's another reason I want to use the 40 gallon res in the room (and need the chiller to do so!).

    What I have been doing as a "flush" every two weeks is instead of feeding 5 gallons I do 10 and the first 5 gallons are at around 200-250ppm followed by the normal 600ppm for the next 5 gallons. I'm concerned this isn't a good enough flush because I can see salt buildup on the pots and table. The plants are not showing any issues at all, not a single leaf, but I'm just being sure to cover my bases here. I guess the salt buildup on the pots are my concern. Please advise...

    For what its worth I test my ppm and pH every time before feed (obviously) and I also check the runoff. What I am seeing is 5.8 pH in and around 6.1 pH out along with 600ppm in and around 650ppm out. I assume this telling me to back off a little more with the feed and do a good flush?

    I would stay away from peat, I think chunky perlite would be your best bet, it's what I do.

    Im sure this has been hit on a lot, but remind me so i don't have to search 130 pages for this info.

    Can I reuse COCO? If so, how?

    If I an I'd assume i need to clean out the roots and then wash it. Would I just use tap water? or is there some nutrient mix in need to make to do this?

    I have a bunch of pots (like 36) filled with used coco. I would rather not throw it all out.

    It is reusable..

    Not sure what other guys do but I throw mine in a pot of boiling water just to sterilize and then let it dry out.

    can anyone answer how canna gets away with the same bottles for veg and bloom? Don't the NPK's need to change for optimal flowering?

    You can def reuse, I actually find it better second go around, if you ran a clean grow, a few roots left in won't hurt, only help with the leftover exudates and such.....

    Sorry, did not see your question.
    That is total ppm for both A&B. I run RO (<15 ppm), so I add one to two grams of Epsom and 1 to 2 ml of Cal/Magic, to get my base to around 120 ppm (0.24 EC) and start from there. I add 3 to 4 ml/gal of A&B which gives me a number of 320 +/-. I have increased that to 250 ppm in veg until I see any signs of over fert. Doing well now at around the 250 ppm point.
    Less is more when it comes to growing cannabis, in my opinion anyway.
    GR
