Ppm 3300

Hey my ppm going in was 650 and the runoff was 3300+
isnt that bad? I am using organic fertilizers and foxfarms happy frog soil with foxfarms strawberry fields soil. I havent had any nute burn yet and this is the first time I used my new ppm meter. Any help would be appreciated.
 
mine were like that i stopped useing ppm meter just made sure ph was right had no problems i think its a headache u dont need to worry about i bet your grow was going fine got ppm meter now your flapping that my experience with them mate
 
Ppm is parts per million of dissolved solids so the high reading is normal coming out of the poop filled soil you are using
 
So, I've been chasing this issue with a variety of soil companies. I hope to complete my research in a few months. What I can say is that if you take a bag of FFOF and pour 50ppm water, 6.0 Ph and 0.1 EC through the soil fresh from the bag, your runoff will be >3,000ppm, 5.0Ph or less and an EC in the 4+ range. How the hell and WTF.

My suggestion is, if you still have some of that soil in the bag, put the virgin soil into a little 4x4" container with good drainage and soak the soil until you get runoff. I'd be curious what your before and after numbers are. Then the question becomes, how many waterings at the "proper" measurements does it take to bring the soil run-off inline with the actual input. What happens if you don't Ph the water or use much food as a lot of new growers do. How many waterings does it take under those conditions to bring soil run-off to proper numbers?
 
Yes yes yes. All them questions are in my head too. The plants are doing good. Not even nutrient burn. Maybe a little or it's a little light burn. Either way they are doing fine. Im going to record it and find out how many waterings it takes. Or how long it takes to show deficiencies with just ph water
your right tho, all my runoff is always between 4.5-5.5 when my water in is 7ish everytime.
 
Testing your run-off can be a good indicator but I'd agree that the slurry test is a better representation of what your soil Ph actually is. This is kind of a "where there is smoke, there is fire" type indicator with the run-off.
 
Never tested my run off water, in my 8 years of growing to be honest.
Always just makes sure I have the right Ph - and I’m doing quite fine
 
Lots of growers don't. Many don't have Ph problems. It seems like an easy and common error to get some Ph issues or lockout, so I usually recommend to check the run-off and see how it compares with what goes in. If they are drastically different, move on to doing the slurry test to confirm or deny that the soil Ph is in optimal range for nutrient absorption or not.
 
If your soil ph is off. You don’t need run off water to tell you. The plant will tell you in matter of no time.
It’s a useless tool for nothing - checking the ppm and run off water when growing in soil.....
 
If you're putting in 700 ppm and getting 3000 ppm out does that not mean that you have either accumulated salts in the soil, which are rinsing out and being measured or the nutrients in the soil are high enough that you shouldn't even be adding any nute's until you start getting below where you want them to be? I was using FF coco-loco and adding nutes. Crazy high ppm's along with nute lockout and burn. Thoughts?
 
The plants are doing fine and growing fast and the ph runoff is always 4-5. It's got to be the soil. I watched the slurry video, and I also have homemade stir plate so that's cool.
I have been giving them less nutes than suggested. Maybe 1/2-3/4.
not really no nute burn yet either. I'm using all organic ingredients.
Should I lighten up on the nutes?
I've read that FF soils can do thisp
 
Thats kind of my hypothesis on the whole thing. If the soil is high ppm to start out, is it best to feed normally or do you give only water and maybe minor supplements until ppm gets to 800 or so? Which grows more plant matter, which one has nutrient or Ph issues more frequently? It's baffling to me. People do nothing and get good results sometimes and others do everything by the book and get bad results all with the same brand / make of soil. Granted, there are many differences (hardness, ppm, Ph, micronutrients) in the tap or well water that people use in the various parts of the country / world.

I do know for certain that with straight coco, watching the ppm of run-off is important because you WILL feed more or less than the target dose based off of the run-off ppm. It is an accurate reflector of nutrients in the medium.

But it doesn't apply the same to soil, how it differs, I don't know. Much more going on within soil, but again, what does it all mean? Haven't found confirmable answers to that.
 
If you're getting out more than you're putting in then there's already enough in there. I'd feed them pd'd water and maybe cali-magic until they show you they are hungry.
 
Gotta agree with chad here, thats how hot fox farms soil is, not only that, nutrients are washed away with runoff
 
I guess my ignorance is showing because... I don't see why you are suprised that there is shit in the water that you are straining though soil that you just put shit in?? If you don't want shit in your water then don't pour it in the shit.
ppm= parts per million of TDS= total dissolved solids...... which is measuring things like dissolved shit or many other things that dissolves when it gets wet. Am I right so far? We put many different amendments into our soil that will dissolve when we water it so that our plants have stuff to eat. Here's where I'm not getting it. Why are we suprised by the fact that there is dissolved shit in the water after it runs through the soil you just put shit in?

obviously I'm missing a key ingredient to this question. Personally I don't pour enough water into my soil to have it come out the bottom because I don't want to wash the shit I just put in it out through the bottom. I do understand that when I was using salt based nutes that to avoid buildup I would let water wash out the extra salt. I didn't then measure if there was shit in it, I knew there was because I put it in there. I did sometimes check the ph because if I didn't wash out enough of the salt it would cause my ph to go out of wack. Again I must be missing a major ingredient or piece of this puzzle..
