keep in mind with all the lime in there your gonna have to feed less or you will lock the plant up,there are soil acifiers to drop the ph but i feel it to late for that,lime and acidfer just fight each other leading to no harvest,im give you a important tip though,next time when you use soil,reguardless of many that say check your runoff,disreguard,soil is a filter,our drinking water is the same filtered water,you cant get a acurite reading threw the runoff,just my opinion,to test after you harvest and flush that soil your using,keep note on how much water you use and what the ph is , do you know how to do a slurry test on your soil?alright, thanks for enlightening me on the slurry test, doing that soon as the lights come on
i looked it up still have about an hour until i can do it, looks like a 5 to 1 ratio in a cup and use the ph pen right into the mud. i limed all the plants pretty good but only went crazy on one, im going to report back witb the resultskeep in mind with all the lime in there your gonna have to feed less or you will lock the plant up,there are soil acifiers to drop the ph but i feel it to late for that,lime and acidfer just fight each other leading to no harvest,im give you a important tip though,next time when you use soil,reguardless of many that say check your runoff,disreguard,soil is a filter,our drinking water is the same filtered water,you cant get a acurite reading threw the runoff,just my opinion,to test after you harvest and flush that soil your using,keep note on how much water you use and what the ph is , do you know how to do a slurry test on your soil?
no i calibrate my pen, i have a blue lab and a cheap amazon one to double check because i am pretty shocked its that low, the amazon cheap pen is a little off but there both pretty close, the leaves were alot worse but i defoliated all the really bad ones. they were all twisted and curling and turning brown and crispy and then hanging on by a thread, i would touch them and they would fall offI use wood ashes to raise my Ph if necessary, since they will provide nutrients as well as raising the Ph somewhat. Lime takes a long time to work it's magic and top dressing won't really help matters deep in the soil. When the lime DOES start working, the Ph swings are going to be problematic. FFOF is fairly full of nutrients, but not to the point that that it will drag your Ph into the 4s. Is there a chance that your Ph pen/device could be reading incorrectly? Your plants look pretty healthy for having a Ph so low, in my opinion.
i meant take some the soil put in glass with ro or distilled water ,shake it up and let settle about 30 min to settle,then stick your pen in the fluid not the mud,this will give a acurite phi looked it up still have about an hour until i can do it, looks like a 5 to 1 ratio in a cup and use the ph pen right into the mud. i limed all the plants pretty good but only went crazy on one, im going to report back witb the results
Slurry is a 1-1 or 2 to 1 ratio.i looked it up still have about an hour until i can do it, looks like a 5 to 1 ratio in a cup and use the ph pen right into the mud. i limed all the plants pretty good but only went crazy on one, im going to report back witb the results
I seriously doubt the ph is that low in fox farms soil. I would be shocked as the plants don’t look that bad considering. If it was in that ph range it would be much worse. Measuring runoff ph is useless. Do a slurry test as oldskool suggested. Use RO water or distilled water for the test.
If you are concerned I’d take as much of the old dirt off the root mass and repot into fresh soil. That should buy you some time and correct some of the issues. Not knowing how to properly test the ph of your soil has caused you to freak out and throw the kitchen sink at it. That’s not ideal and your plants will suffer from it.
To test runoff you need 0 ppm water and even then it will be inaccurate as some of the water will run through channels and straight out the bottom of the container. A slurry test eliminates this margin of error. Anyone who says otherwise has no idea what they are talking about.
I used a new mix of soil ingredients recently and I added my usual 1 tbsp lime per gallon and now I'm constantly fighting to keep my pH under 7 this run, so with how much you put on your soil I personally don't think you're going to have very good luck.did a 1 to 1 slurry on 4 of my 6 plants
the one i hit with the bunch of lime measured at a ph of 8.4 and i forgot to do the ppm
the others were;
ph6.1 @ 40ppm
ph 7.3 @ 100ppm
ph 6.5 @ 80ppm
i used distilled water with 5.7 ph @ 0ppm
i tried to take the soil samples as far down as i could to get away from the top dressing of lime, probably got the samples @ 3 to 4 inches below the surface of the soil
whats you guys' opinions on these results? do you think the soil thats deeper is a lower ph because the lime was applied at the top? and my ppms seem to be low too (the pen was set at ppm 500, i guess thats american and ppm 700 is European)
trying to figure out where i should go from here
Runoff is only useful if you can get the water to travel through the growing medium and not around it and through channels. If it travels around the growing medium and not through it you’ll pick up mostly salt buildup on the container which will throw off the readings. Plus there’s the issue of which part of the runoff do you test? The start, after running a gallon or so through it or later? By testing the soil directly you’ll get an accurate measurement that you can then make adjustments with.
One useful tool is to buy nectar for the gods Olympus Up and Herculean Harvest and use that as a flush every couple weeks. The calcium binds to the excess nutrients and renders it null. It also flushed out excess salt buildup and delivers a boost of phosphorus to help with nutrient uptake. It’s cheap and is useful to have in your arsenal.
before I started adding a recommended amount of dolomite I often experienced low fives and even high fours a time or twoI use wood ashes to raise my Ph if necessary, since they will provide nutrients as well as raising the Ph somewhat.
