I went through a lot of the old posts to try and find a definitive answer on this and was unable. So I will ask here.
I am growing in FF Happy Frog soil. I keep my ph on or around 6 and my well water I use has around 320 ppm naturally (high, I know).
When I use my fox farm trio at half the suggested dosage to feed EVERY OTHER watering, it ppms at about 1,300.
I regularly get about 100 to 200 ppm higher on my runoff (1400 to 1500) with a good PH of between 5.9 and 6.
I have read that you want LOWER ppm out than the ppm going in.
If I need to drop my nutes to a quarter, I am ready to do that.
My plants are in their second week of flowering.
I have also included some photos although I doubt you need them for this particular topic.
Yeah, I definitely don’t have any signs of nute burn or deficiency for that matter. Just want to make sure I am NAILING it, you know? Getting the science down. Thank you for taking the time to answer me.
That my ppm is higher in my runoff by 100-200 ppm than the fertilizer/water concoction’s ppms when I put it in.
For instance. My ff trio is at about 1300 when I pour it in the plant.
You still with me?
And then it is about 1400-1500 ppm on runoff. PH is fine. In and out.
This happens to me alot also, I contribute it to the speed in which I water.
Do a soil slurry. Get a soil sample from somewhere around center between pot wall and center mast of plant. Go 2 inches below top soil. Take sample and mix 1:1 with distilled or RO water. (I do 1 tblsp each) agetate and stir for 1 min then allow to settle for 15 mins. Ph and tds the solution for an accurate reading. Runoff isnt the most accurate way to tell, its ment more as a guide. Track it and use it to tell when something has changed. I like to feed when runoff is around 800-1000ppm.
This seams low to me. I ph to 6.8 try to keep my soil/runoff around 6.5. 6 is kinda low for phos in soil.
Your plants look mad healthy though. Im not sure I would change anything your doing.
Thanks, bro. They are healthy as **** (you believe they don’t allow cursing on here?).
But I feel like there is always room for improvement in my grow game, you know?
Maybe the PH adjustment you are suggesting is the improvement I am looking for?
Thanks again, dude.
It depends. Some plants its a part of their genetics others (most) not so much. If left unchecked it can give you alot of imature trichomes. There is a difference between foxtails and whst I was counting as foxtails. Ill show ya what I mean.
Don’t want to start a new thread so I’m going to try and use this one…so two days ago i did a straight water only and runoff was 800 so i went to feed and today runoff was 1200 im currently using jack 321 and ppm in was 1200 should i be worried or was the soil so dry that the nut water went straight through…i also spaced out the feeding so not to dump it all at once if that matters
