Your medium:
7) Specific brand and type of soil, (coco, peat based soilless...) and anything you've added to it. (vermiculite, perlite, worm castings...)"Miracle Grow Potting Soil"
.8) Size of container.Not sure (see pictures above for an idea)
.9) Did you use peat pucks (or similar) to root clones or germinate seedlings?
No Folded two paper towels to germinate, then put in soil.

Your nutrients and water:
10) Source of water? (tap, bottled or filtered) What's it's ph before adjusting?[/COLOR]
Filtered water, put into a huge jug and left in my room. No way to check ph
11)Method of checking water ph. (ph pen, test strips, aquarium test kit...
No way to check ph
12) Method of adjusting water ph. (phosphoric acid, white vinegar, hydrated lime, PH Up...)
No method to change ph
13) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule.
No nutes given yet!
14) How often are you watering between feedings, and how much per watering?
About every 3 or so days. I check the soil with my finger from the top and from the drainage hole, if there is no moisture on my finger after touching soil I will water
15) Any additives or tea's? (Superthrive, CalMag, molasses, Mother's Earth...)
no.
16) Are your ph levels stable, or do they fluctuate?
No way to check ph
17) What is your ingoing water's ph? ...your runoff ph?
No way to check ph... runoff water has a yellow tinge, don't know why?
18) Do you foliar feed? If so, with what, how often, and at what time do you spray?
Don't know what it is and don't do it.

Your growroom:
19) Indoors or outdoors?
Indoor
20) What size of closet, room or hut?
10ft wide, 4ft deep, 15ft high (appro. numbers)
21) What are the temps and humidity levels while lights are on? ...With lights off?
Lights on:27degrees C 80 degrees F ...ranged from (23-29 degrees C though)
Lights off:no sure
22) Have you seen signs of insects in the growroom?
Not that I know of. (knock-on-wood)

Your strain:
23) What strain are you growing? (Indica dominate or Sativa dom?)
Bubba Kush (Bubblegum x OGkush) 80/20 (indica/sativa), indica dominate
24) From seeds or clones?
Seeds
25) Is this an autoflower strain?
No, it's not.


There are signs of slight(knock-on-wood) nute burn on my plants. Is it from the Miracle Grow Soil? ... so is there a way to make there be less nutes in the soil? Or an alternative I can do?

Got some pics?

If it is nute burn then yes it's likely one of the "Time release" (the little opaque beads that look like plastic) balls popped right on a root. Which is part of the reason that MG is not recommended, since it's basically impossible to control nutes.

That's a huge space for a seedling, so the lack of a fresh air source isn't a problem yet,... but it will be later in the grow. Get that fixed ASAP.


Get an aquarium PH droper test kit,.... they're like $5 USD and will save your ass from PH lockouts. Then get PH UP or PH DOWN (which ever way you need to go) and get your PH to 6.0-6.5 for your inbound water.

If your PH is incorrect the plant won't be able to uptake nutes propperly causing all kinds of problems including the plant straight shitting the bed on you.

Get this lack of PH monitoring fixed IMMEDIATELY!

Good luck brother! :weedpoke:

I will get pics up a little later, sorry can't right now.
I am planning on getting some ph test strips online just for now because of my budget. Hopefully I can also get my hands on some of that ph up/down solutions

This miracle grow bag only said premium potting soil or something like that and I didn't find out until 2 weeks into veg that it had time release nutes in it( and yeppp your right, it's those clear, little opaque beads that look like plastic) has those

[poker2]

There we go!
Special Thanks to Rusty Trichome :thumbsup: for giving me instructions on how to get better/clearer pics
-That 4th pic looks HORRIBBLEEEE!!! I just noticed that today as I was taking the pictures (worries me)

Some more pics

Can anyone confirm that it is in fact nute burn?
And does anyone have any idea's on how I can deal with this? (....I'm thinking about this but don't think a flush would do anything would it?) and doesn't flushing stress your plant (isn't it like overwatering?)

[Agoblue97]

After looking at the pics you might have a slight nute burn going on, but that's not what your problem is. You need a way to check ingoing and runoff pH lvls. My guess is your soil pH is low which is starting throw the plant in lockout.:thumbsup::thumbsup:

[WashougalWonder]

Yes it is nute burn. You see, every time you water this potting mix, it releases nutes....well too much for cannabis.....Find just a basic potting mix without all the nutes.

[poker2]

So what is my solution now?... do I take out this soil and change it?(How much would that stress the plant?) or what am I supposed to do?

[canniwhatsis]

Not sure if it's the best course of action with the time release soil but you can flush with PH'd water, 4-5x the volume of the container to strip some of the excess nutes out.

I'd just worry that it'll strip some of the needed nutes as well, and I'm not sure that a light feeding would be a good idea with the time release. Where's Rusty? he knows more about that soil than I do.
