    Bump. Good read, I gotta get me up to speed on dosers. I didn't before because RDWC, but now I'm in soilless and this is making a great deal of sense.

    hello
    back again sorry I was gone for a long while

    no I have no pro green house experience... but I have read a lot and made many mistakes that taught me a good bit

    the doser I use are advertised for chicken use ... theyre the least expensive and have worked well for years without service... the only down side would be the mixing ratio is fixed at 128:1 where as the high dollar dosers you can change the ratio

    HYDROPONICS
    A PRACTICAL GUIDE FOR SOILESS GROWER

    it seems advanced and took me a long while to grasp it, but I eventually did

    its strange to think back on how hard it was for me to figure it out and now it seems so basic to me

    sorry I never got back to you friend

    several years at minimum

    I have considered options allowing N leaching in late flower

    what I thought to do is mix 2 sets of stock solution (4 containers)
    and just switching the doser tube over to the other stock container at week 4 or 5 or 6 or whatever

    so the first set of two stock containers would feed the first part of the flower cycle and the second set of two stock container could feed the later part of the flower cycle to reduce N or leach N

    but after years of doing it both ways (I started out in recirc) I find the benefits to adjusting the nutrient ratio to leach N is unnecessary and has little to no baring on the finish product
    in my experience the only need to leach is if your feeding to high an EC... if your EC remains low and within range you wont need to leach

    I also find... I can control or reduce N in the plant simply by allowing the ph to climb and stay between 6.2 and 6.5.. which naturally happens in the medium samples as you reduce watering late into flower

    the reduction in watering frequency and shorter watering durations will cause the medium ph to rise a great deal

    recently I have adjusted my watering schedule... I used to water 1 min an hour but this casues an EC climb within the medium because im not getting enough fluid thru the cube to rinse out the old

    so now I set my solution ph to 5.5 I water 5 minutes every 4 hours and the medium ph stays good at 5.8 ish

    Im currently feeding an EC or .08 and the medium samples are like 0.7 which is awesome

    you can see from the pics the leaves are slightly torched or twisted... this was the result of a quick ph swing/change

    I started with a new product Pekacid
    and had to figure out how much to mix to get the ph correct...

    the ph in the medium was running a bit high 6.5 causing zinc, Mn, and Fe to be locked out

    I lowered the ph of the stock solution using sulfuric acid and gave them a foliar feed of peters s.t.e.m. 1/4 tsp per gallon

    the yellowing at the top (micro def) corrected itself over night but I got a little bit of leaf curl

    all these plants are satori f2 and only a few days into 12/12

    satori x satori (made by me)

    fan leaves are huuuuge

    my first time growing the f2s

    I took the lower branches for clones to sex them
