I've been using about half a gram once a week, but if you're seeing deficiency, I'd do a gram per week or so. Of course your water and your feed may suggest different. ;)
So honestly she’s been so much better overall ! Like a whole 12 hour difference less yellow at the tips much more green. I had a bottle of this life water & have been watering with that & I think it loves it !

May or may not be because of that specifically as much as just watering may be helping dilute or remove any over-feed from your medium. They state that it's 'pH balanced' but give a range of 6.4-7.4, which is more of a range than I'd like...not to mention that it's expensive to be watering that way.

Are you not pH testing and adjusting your water?

That also, I think it’s more of the food diluting out ! I only had one bottle I’m not buying more .. no way ! Lol too expensive I’ll stick with my Brita filter water.
& no Iam not test the PH should I ? Adjusting my water in what way ?

I have this meter but I think I need a new one it started to act a little funny with my house plants.
but I stuck it in there & it does say 8. I assume I need more acidic soil but too acidic ?

think about getting this one

We're not taking about killing bed bugs nor does a grower go spreading the dust all over his or her home. The grower eliminates the dust before use.. Well some of us do..
Diatoms are as small as 20 microns, not much larger than dust particles. It's quite easy for them to be gently blown about when you have a one-inch pile on the surface of your soil, assuming that you have good air circulation below the canopy that is.

A natural fluctuation between 6.2- 7.5 is normal with organic cannabis. Due to it preferences with wet/dry cycles of the soil, the pH(KCI) will change.
pH(KCI) will also change based on exudates from the plant and Microbes. As well as which element and how much of it is being taken up by the plant. This changes the chemistry of the soil and consequently the pH as well. KCI

Your ingoing pH(h20) should be 6.5 always. Even in flower. Altho flowering plants like a more neutral pH all around. Don't fight pH drift in flower, it's going to rise slightly. Totally normal.

Absolutely not. Don't buy that. It's entirely not up to the job. And really for the most part junk.

Buy a 'pen style pH testing meter, they can be anywhere from 10 bucks up to hundreds. Buy the calibration solution & some storage solution. Test your water before you water and your feed after you've added it to the water and adjust with pH Up/pH Down (etc)depending on what you need.

In soil you're looking for a pH that's in the 6-7 range. In coco you're looking for something slightly lower than 6.

Okay sounds good I’ll buy the pen style.
How about this soil ?

Not one I'm aware of, so I guess as good as some of the others? ;)

Again, I'm not an all organic grower. I'm more of a 'use a medium that's fairly inert' so I can have control over things. Lots of guys here can fill you in on organics with way more knowledge.

So because it’s an organic soil I have to use organic fertilizer?
but yeah seems like a good soil so hopefully it does well!

That will work. I like Epsoma amendments and tone fertilizers, and I use it alot outdoors.
I'd add a little bit of compost to it and a pinch of Dolomite Lime. That potting soil is peat based so it will get acidic over time.
Dolomite lime ? What does that do ?

No you don't have to, you can use synthetic fertilizer in organic soil not problem.

It acts as a ph buffer for your soil, keeping it from dropping too low. That Whitney Farms soil isn't bad, but it's surprising that it doesn't seem to have any sort of ph buffer added.

No you don't have to stay organic. You can feed liquid nutrient salts to your plants, you just won't get the benefit of the microbes because your not giving them anything to breakdown and feed to the plant. You can still go quality bud without organic methods.

Dolomite lime ? What does that do ?
Dolomite lime is a horticultural liming product use to adjust the soil pH. Lime is what raises the pH and sulfur is what lowers it. These are the two products you'll commonly find in stores or on line to adjust pH. Don't worry about pH right now.

Buy a bag of quality, organic certified compost. Get some EWC (earthworm casting) while your at it also.

Mix 10% compost to the volume of potting soil.
Add 5 - 10% EWC also.

Just be aware that when you fertilize mineralically, you need to drain & waste the old nute solution out of the pot or it can lead to a toxic salt buildup.
Which implies you will also get rid partially of beneficial bacteria, humics & other stuff that is currently embedded in that organic soil.
Another main difference of organics vs mineralic is that organic is typically 'slow-release', so in times of quick need a mineralic feed can be a more quick remedy of a deficiency.

So should I just go to regular soil?

I'm a huge fan of organic. To me nothing beats it. It's very forgiving and takes alot of the daily monitoring and adjustments out of the chore list because the soil is what feeds and grows the plants. You feed and care for the soil.
With salts you'll have to be diligent with daily or every other, checking pH, PPM/EC. It is a more controlled and precise management over nutrient and soil.

So I’ve been using my Brita filter & it’s been working & growing sooooo fast !
