I havent watered with a run off. I just watered with 6.0 until now. So next feed will be 6.3 or 6.4. My friend it makes sense what you say that maybe there is a lockout. But i added garden lime in my soil which makes the ph neutral 7. Like this even with ph 6 that i watered, it should raise up to 7 slowly and unlock the nutrients. Im so disappointed right now.

Not sure if adding lime would screw with your soil as biobizz soil etc is already built to buffer to a pH of 6.5 if not mistaken.

@hashead My friend. i just make the run off test. i give ph 6.4 and ec 0.5 and come out ph 6.0 and ec 4.5 !

Read the comment above. I think i might overdone it with lime in soil. 4.5 EC !!

Okay, dont panic. Your soil is slightly too acidic, maybe 5.7ish id guess. This could be the cause of your lockout. Also its too acidic for microbes to thrive, microbes break down your lime.

I measure with ppm, but that ec sounds high. I wouldnt reckon its a build up of nutrients as youve only given one feed with nutes, probably the lime.

If you have more biobizz, id just transplant and maybe topdress with lime.

If you dont, id just water with a higher ph, 7 would do it but will take several feeds to adjust. If youve got ph up itd be no harm to push it to 7.5 for a feed or 2.

Once you get that ph in range youll be sorted. And yave still got time before the big growth spurt

Oh God. I just put them in shower and flushed right after i saw the big EC runoff. Shower water is ph 8 and ec 1. Now the EC is running off at 1-1.5 and ph at 6.8-7. After 7 hours under the light they become greener and look alive finally.
But pots are fully wet now and it will take a week to dry out for sure. This fckn lime fucked up everything. All the biobizz soil i ordered is gone and is really expensive to ship here more.
My friend if i could see your message before i make the flush i think it would be better. About the EC i want to ask you, lets say i feed 1.2 then how much should my runoff be?

Ok, a flush aint a bad thing once ya dont drown the roots, ya got lightmix and perlite in there so drainage shouldn't be an issue.

If ya have a small fan you could blow air on your pot to help dry it out quicker.

Your runoff EC sounds better, I think 1-1.5 is what your aiming for.

Next feed, ph to 7, EC 1.2 and check your runoff.
If the ph is between 6.2-6.8 your within range to avoid any nutrient lockout.

If your EC runoff is lower than 1.2 it means your plant is using up the nutes in the soil and all should be good.
If its higher it means nutes are building up and been washed out of your soil with your feed. And you can lower your nute dose rather than overfeed em.

Dont worry about watering again untill the pot is bone dry tho, just relax for the next few days lol

Great. I have 4 plants and i flushed them until i got different ec readings. [HASHTAG]#1[/HASHTAG] has ec 1, [HASHTAG]#2[/HASHTAG] has ec 1.3, [HASHTAG]#3[/HASHTAG] ec 1.5 and [HASHTAG]#4[/HASHTAG] ec 1.7
Should i flush [HASHTAG]#3[/HASHTAG] and [HASHTAG]#4[/HASHTAG] more to bring them down to 1.3?
Lets say i feed [HASHTAG]#4[/HASHTAG] solution with 1.2. Will this be correct? How i will know if there is no lockout?
I see there is ec metets for soil in ebay. Will this be similar to run off test?
Also i would like to ask: the ec of the soil will be adjusted by time depending on my feedings and from the roots eating?

If i test my run off with distilled water ec 0, it will give me a correct reading of the true ec of my soil, right?

Personally i wouldnt flush again. Id let the soil do the work for now. Sometimes when we have issues we wanna try a million things to fix it when really, less is more.

If your plants have started to look greener and healthier, and your runoff ph is between 6.2-6.8 you can be 90% sure you dont have lockout.

If its the type of meter you stick in the soil I wouldnt bother. Testing runoff is fine for monitoring you soil ph/EC.

Yea that it exactly, you put in food and (if everything is good in the root zone) the plant uses it.
Use your EC to gauge how "hungry" your plants are.
If your runoff is equal to or higher than what ya put in ya can ease up on the nutes.
If its slightly lower then your on point with the amount your feeding.
If its a lot lower, you should increase your dosage.

Id take a soil sample, mix with distilled water, give a good shake and let sit for a half hour. Strain the soil out and test the water. Id test ph rather than ec, in soil EC can really fluctuate.

Because your not just testing nutrient salts, like in hydro. Instead you have salts, microbes, fungi, organic material etc which has an effect on the EC reading.

Beginning to grow and come up with this problem has made me realise important things. Respects to you @hashead for the proper explanation and the lesson

They do look more alive and leaves pointing up now. As for the green, they still have some pale color but i guess it takes some time to recover the roots right?

I've got no idea about EC or a anything I've never checked mine but If you can get a bottle of biobizz Activera a couple of feeds with that will help with anything from overfeeding to under feeding its like medicine for them. Better than say getting more soil shipped 1litre bottle in the UK is £9 or so
