My ph is always at around 5.8-6.2 i think that is where it should be but i could be wrong.
How did you test that pH?

If the bag didn't mention dolomite, that could be a problem later in the grow. Even if it did mention it, the quality of the product sounds (looks) suspicious. (If they didn't include the perlite they said they did, I wouldn't count on them adding the necessary dolomite.).

You should buy some dolomite. You may need that in flower. (Powdered/sand consistency is better than chunks/pellets. Dolomite is characterized by a ratio of calcium and magnesium *carbonates* at a 1.2:1 ratio. If they label doesn't have that, be careful.).

When I did soilless, I pH'ed my nutrients to 5.9 in veg, 6.1 in flower.

I herd a 3/5 gallon pot should suffice as i'm not looking to grow a huge plant just tryin to survive veg to harvest to get a feel of things for my first grow, is this correct? Watering around the edges is absolutely genius, will def start that. For number 3 i don't really understand the terms, i'm quite the noob haha :3 Thanks for your tips!!

ok know this a 3 gallon pot of soil only holds 1/2 gallon of water........ 5 gallon is about 3/4 of a gallon give or take a pint
any more then that the water leaks out .....the feed plans on the boxes are ment for 1 us gallon of water (that much feed to 1 gallon of water )

do not keep the water it will not last untill the next feeding ....mix it up use it dump the extra out on a plant outside

i tested the run off with a pH meter, i will look into it, would it still be necessary if i have calcium and magnesium additives that i give to the plant?

Runoff ph doesn't mean a lot. I use a Control Wizard Accurate 8 ($70). There is a tedious way to measure runoff. You could try it to see how it compares to measuring casual runoff. Google for NCSU Pour-Through Method Runoff.

Dolomite buffers the medium. It's also a food/supplement. I would get some. When you transplant, I believe it will help if the additional medium were amended with 1-2tbsp/gal dolomite. I don't have a good feeling about that peat you bought.

I have another plant that's half way through veg and thriving extremely well so i don't think the soil is a problem to them, but for the dolomite do you think cal mag from botani-care or general hydroponics will suffice? I checked out dolomite and that shit is super expensive, thanks!

No, that's not the same. I'm not sure why it's expensive. Mine cost about $1 US per pound. At 1Tbsp/gal a pound will treat about 50-100 gallons of soil.

People who grow organic will use crushed eggshells, clamshells. There might be some alternatives available to you. You could visit the organic section. But, I don't know how that would work with soilless.

Yea ill look it up more, but for now my plant is seeming to get better and my other one in veg is growing super fast, if problems arise i'll know it dolomite will be needed, Thanks!
