Miracle grow ph ?

It works great; check my journal.

Its pH is the same as just about every commercial potting soil: 6.5 or very close. Why? Because just about every plant in the world thrives at that pH and obviously, they want their product to succeed in as many cases as possible.

MG soils should really be run 3-4 weeks before you add any outside nutrients; they already have nutes in them and adding more is usually overkill. I'm not familiar with bio-tone. Usually, bone meal and blood meal are used together in soil mixes to balance Phos and nitrogen. Don't use bone meal by itself, whatever you do.

I would just skip all that and get some Dyna Gro (dynagro.com) Foilage Pro (9-3-6) -- use that until about 4 weeks after you switch to 12/12 flowering cycle and your height growth has leveled off. At that point, go to Liquid Grow 7-9-5 or other fert that's relatively balanced across NPK. I switched to these this year and they're doing great. They mix right up to pH 6.5, too -- right on the money for MJ (and virtually all plants).

Don't buy the hype that MJ requires massive amounts of P and K during flowering. It's BS. If you go around and track all the "Help -- curling spotted leaves!!" posts on here, you'll see that dousing MJ with high PK stuff is the common root. But, if you're just starting, you needn't worry about all this yet - you've got 3-4 weeks to research and figure it out.

Of all things, remember that MJ is a plant. It's only "special" in what it does for us, not in how it grows and feeds. In that respect, it's the same as about 98% of the plants in the world.

check out the miracle grow perlite.that's all i grow in.this is a hempy bucket,nice and easy:bigjoint: also you don't need nutes for a few weeks because it has it in the soil already.

the ph levals are normally on the back of the soil bag, as for not adding anything to the soil for a few weeks i tottaly agree this has actually happend to me and it is not a good thing, my plants got the shit burnt out of them from the nutes,

does anyone know anything about the MG plant food? i have heard it is good and that its bad just looking for opions, i am using the bule powder kind that you mix with water

yea I start off with half of the little spoon side I think it's 2.5, around the 4th week then gradually increase, I also use the MG time released soil. Total MG grows.
I hate when ppl bash MG. It's good and cheap and easy to get. You just gotta know how to use it. It's not the best way for a beginner to start off with, that's for sure, but onece you get the hang of it 3-4 grows, you'll pretty much have it dialed in.

try the liquafeed plant food just use a tsp per gallon. if your going to go with soil you should try 1 hempy bucket with your other plants and see what works better.i bet you ditch the soil for your next grow..i know i've done it.
what do you have for lights?

The blue powder MG 24-8-16 is in the perfect ratio all the way until stretch ends; a little short on micros, though. MG stuff counts on the soil to provide micros, which usually works out fine. Personally, I prefer Dyna Gro stuff because it contains full micros, a good cal/mag balance, and no urea N (MG stuff uses urea, which is okay if you're feeding is in tune with the plants' need. Not good for resolving deficiencies, though, and carries more burn risk if you overfeed. Dyna Gro, Foxfarm, Jacks and others use a balance of nitrate and ammoniacal N - faster acting with less burn risk).

Start light; no more than 1/2 dose; work up to full over next 2-4 feedings. Don't feed until you reach at least three weeks of growth if your using one of the pre-ferted soils.

Im a new grower and I need help .I just bought some clone from a dispensary and my foxfarm ocean forest haven't came yet . So I bought some cheap Miracle-Gro soil to plant them in. My house water pH after I reverse osmosis it is 7.2 . I started watering it with the water . It came time for a feeding and I mixed my nutrients not checking the pH because I didn't have a pH meter at the time . Then the yellowing and the droopy leaves set in . When all my grow things came in from Amazon . I was able to check the feeding pH and it was 5.56 , I know that wasn't right so I up the pH to 6.2 . And it looked like it got worse . Then I up the pH to 6.5 and I don't see no change. If anyone can help I would be very grateful.

Did you calibrate the ph meter? Some miracle grow products have time released newts(not good for growing cannabis)if you have to go with hardware store soil, I would recommend going with black magic potting soil. If I could growth with mine it's about $17, the bag is 1.2 cubic feet you can get it at home depot. They are on 2nd week of flower.20200224_101621.jpg

Yes I calibrated the pH meter thanks for the advice but my Fox farm ocean forest soil just came in so when the roots ready I'm going to transplant them in that soil.

Don't worry about the PH if you're growing in soil. Toss that meter in a drawer and forget about it.

Take a pic of the Miracle grow bag or post a link. Does it have perlite mixed in?
