you need actual cannabis nutes. it's used what it has in the soil and is eating itself to stay alive. miraclegro isn't balanced for cannabis and will probably kill it quicker. but give it a shot if you aren't going to get set up proper.
edit : it'll stay super slow under that lighting so you...
it's kinda funny as we're legal and the others aren't. i've never had trouble getting anything from anywhere when it comes to seeds.
pre-legal there were enough seedbanks in canada no one really needed to get them anywhere else.
looking forward to seeing you run those strains.
it's better your details are outside of the country where your law enforcement can't get at it. they can still compel seed companies inside nz to release that info.
@Herbies Seeds still ships to nz.
would help to know how it's built. there are peat or coir bases and most media has a host of different things in it. you have to know your media for both ph rules and the type of nutes to use.
that's better. aside from the pics that is the minimum info we need to begin to help.
which brand ? is it buffered ?
light is adequate for 1 plant. will struggle with more.
you're not feeding quite correct. read through this...
nicest buds are the ones in the jars. i laugh at the soil or not debate. ten years ago if it wasn't hydro here you couldn't give it away. now all the same losers are claiming organics are the answer. it's just marketing and fashion.
when we sold we told them whatever they wanted to hear.
plant looks good in the photo. is it just the one leaf showing ?
i hate having to drag information out.
what is your media ?
what is your light ?
how many watts is the light ?
how often are you feeding ?
do you have a tent ?
do you have an exhaust fan and scrubber ?
what is your rh% ?
what...
you could probably pull that off. all depends how long you veg. most plants take a minimum of 1 - 1.5 sq/ft. everyone tries to squeeze more.
a lot of folk would grow 1 plant trained well or scrogged in that size. a lot hinges on your grow method.
you really haven't given us any useful information.
a pic of the whole plant at minimum.
edit : the nutes look like a fairly straight forward 3-part. shouldn't be too hard to figure out. there's thousands of similar 3-part nutes. they are the industry standard.
looks like a few things going on. no way to tell with what we've been given to go on.
