Nutrient lock out will make your plant stop eating nutrients and is often caused from PH imbalance.
If your ph is off no BIOBIZZ for your plant.
someone said thats ph of allmix will never change when watered so u suggest to keep ph'n water
Unless you have PH perfect nutrients, they're going to alter the PH of your tapwater. Because of this if its thrown out of optimum range 5.8hydro 6.5soil
then you need to get it back to optimum. If youre worried about it, just mix a batch and test the ph of it :P
Don't adjust the pH of your netruents in biobizz, They are 100% organic, so contains no salts unlike synthetic netruents, adding Non organic pH adjusters will harm the soil. The soil will hold the pH accordingly.
Hope your tapwater is the magical number then. Good luck with your grow!
After I let my tap water sit out for 24 hours it usually raises PH to about 7.5 which imo is too high for my soil and needs to be lowered to around 6.5.
Then on days I feed, the same water sitting out but after mixing nutrients in will sit at about 5.5 which imo is way too low for my soil and needs to be raised.
Even if I had nutrients that didn't affect the PH of my solution, my initial tapwater being 7.5 would still be too high which is why I adjust... granted I could be completely
wrong here first time. I guess it all would depend on the PH of your tap? Sorry I've just confused myself on this one I hope someone can chime in.
Can someone answer a basic question,
Why doesn't the ph of water matter when using organic nutrients? I simply don't get it.
The biggest problems I have have had with soil is using organic nutrients when it goes acidic later in the flower cycle.
Biobizz nutes being the classic example in my experience.
So it's ok to water with a feed in 5.0 in soil?
just because someone hasn't had any problems, doesn't mean to say others won't.
Has someone actually tried using a oh of 3.2 or 9.8 or whatever using biobizz nutes in organic soil and had equal results to a textbook ph grow?
The soil buffers the ph, so no need to mess with the water. ive done a few organic grows useing plant magic oldtimers feeds.
Tried a few different composts and never once adjusted Ph all grows where trouble free, apart from mites lol.
I dont think anyone is arguing whether or not it works, rather are we wasting or time phing the feed, or is it maximizing optimums like everything else in growing?

I read somewhere it can have a negative effect, throwing the balance of the medium off.
I dont know the science behind it though.
What people are doing is adjusting the water with a synthetic pH adjuster, either up or down, They contain salts, where as organic soils and netruents dont, The microbes adjust the soil, (this is organics, any salts added to the soil will kill the bacteria in a sence, Im sure there can be some fluctuations in pH but thats what the micro-herds or what ever its called do for the soil as such, buffer it. If you are conscious of pH with organics, use organic pH adjusters.
i get all sorts of lock out and deficiency if i dont change the Ph to 6.5
after 24 hours plain water Ph is just below 7 usually and when i add the grow & bloom it is at 6.0 - 6.1. I have even seen it as low as 5.9
It takes about 1/2ml liquid Si to set 3ltr back to 6.5
no adjustment needed when using topmax alone as it sits at 6.5

Keep it coming chaps, a healthy debate is always great for learning
When I used bio biz I didn't Ph anything.
Didn't know what Ph was. Hehe.
Just let the water stand in a bucket for 24hrs or so, mix in food and then feed. Only had a few Mg difs I think??
Must be the most simplistic food you can use.
I use biobizz and have had some problems with every grow I do. I figured it was my ph levels were too high.
When I finally bought a ph tester I found my water ph was 7.0 and my run off was coming to 7.5!!
So I figured my plants weren't getting the nutes as they were locked out.
I then used a ph down adjuster which was for hydro. That made it worse.
Then one of the members here suggested I needed organic ph adjuster. I think it was green Buddha? I have started to use it and it I can see my plants getting better.
Cause my run off always go up, I ph down to 6.3 or 6.4 and gives me a run off of 6.6 or 6.7. I can see that is helping. So for me it's working.
But I have noticed when you feed bio grow that naturally brings the ph down anyway so an adjuster isn't needed some times.
I try to regularly check my run off to make sure I got the right ph level when I water or feed.
Hope that helps.
It depends if you're keeping your grow 100% organic. If you're using organic muck and nutes dont use chemical ph up and down in the water or any other chemical additive, the soil will buffer to the correct ph. If your grow isn't organic dont use organic nutes. Most problems with bio bizz are caused by adding chemicals, causes havoc with the micro herd but doesn't kill it off completely so you get a poor plant.
Chemicals and organics don't mix well
An organic Ph up has been difficult to find for me, anyone have any suggestions? Someone mentioned liq silicon, is it safe to use without harming the micro herd? I'm slowly piecing this together I think.. Tabbs was right when he mentioned about your location. I think hard water suits bio bizz without the need for Ph'ing as the acidic nutes will balance it out. The micro herd will buffer the Ph to a certain extent but going anywhere below 5.5 or above 7.5 you will probably run into a lockout. In my view the best option would be to flush through with water at 6.5, molasses is a good option to lower the Ph while still replacing some of the lost food within the soil (micro herd) or you can use organic Ph down. I've got canna's one but as I say they don't do an up.. which seems weird.. or am I just useless at looking for stuff? lol
Cheers anyway guy's
