Miracle grow soil...

Hello, I realize the miracle grow soil topic has been went over a thousand times but my question is this. I have a 18 gallon pot full of miracle grow soil with a grape kush plant growing in it (doing fine by the way). It is an outdoor plant. Since it is an outdoor plant it will take longer till harvest (planted in may harvest in October). Now the bag says it will feed for six months and since it will be in the pot for six months before harvest I would believe most all the nitrogen would be used up (Or will be after a good flush towards the end). So should I use a organic bloom fert say a couple weeks into flower or does MG have enough P and K for an entire grow start to finish? Right now it is just starting to show flowers and is about 5' tall.

1) Please do not waste my time or yours with "you should never use miracle grow" post.

2) Only reason I am using it is I had to get plant out in a hurry and that's what I had readily available.

3) I know MG is time released and never to use time release ferts

4) Any help or comments other than telling me MG sucks will be greatly appreciated.

Yea it's not "great" but I used the organic choice mg last time and it worked fine for me (other then having 5 for 5 males, the we're nice big and green) there is some ppl that swear they get good results from mg, I can't answer all your questions but for #3 a big part of why people say not use time release nutes is bc a lot of people will add other nutes and it burns the shit out of them...so just be careful if you end up deciding to add some, maybe wait till you see that it needs fed, there are several ways to notice and if so deff make sure you do at least 1/4 of the bottles instructions....goodluck

The safest thing to do with time release grows is leave them alone if they look healthy. But you have to push limits to find limits so it just depends on your goals.

I would only be adding P and K and I believe but not sure that it is harder to overdose on P and K than on N.

Since you only have one plant going, leave it alone until it shows signs of needing more. You can definitely fuck up a plant with too much P and K.

The real issue is the high continual Nitrogen release when you start flowering. Water flushing won't really make a difference because the nutes are "encapsulated" meaning it's going to release slowly no matter what you do. Since you already know it's not an ideal product, personally I would have added more perlite to it and consider a cal/mag product after the first month of growing. I've had good success with it in veg, but flowering is a different story.

Lastly, if it was me, a week before you begin flowering, I'd flush it very well with a product like Clearex (or something similar) which will break down and flush out all the remaining nutes and then begin a regular flowering nute program from AN or Botanicare. I think this will insure your best chance for success.

I am using MG and Sta-Green on my 8 plants, Blue Dream & Pineapple Chunk, I started two weeks ago supplementing as they are flowering now, the PC 3-4 weeks ahead of the BD. I am using Advanced Nutrients - Micro, Grow (1/2 dose), & Bloom now every other feeding, I added Bud Igniter first 2 feedings at beginning of flower. The plants have responded well! This is guerrilla grow and I was away because of work for 1 month and we had no rain, so back just in time, I feel the nutrients in the soil are mostly depleted by now (holes were dug in March, plants put in April 14th. My NPK is 9-8-11 now. I have to go back out to work for 28 days Tuesday and plan to top dress with some 9-12-12 (expert gardner from Wally World), hopefully the rain will come and I'll be ok. I have also been spraying BT & Spinosad these last 2 weeks, alternating every 4 days to stop the onset of corn/bud worms, as I've seen some of their turds around. Just don't get too carried away with the NPK balance and you will be fine. BOL to you.

couple shots of my children hope you don't mind:

miracle grow mmmmm shame its from scotts who got bought by Monsanto ...but you didn't know that ..?

had some mold on this PC (one branch) chopped this branch & bagged it for trash when I first saw it:

You have first hand experience flushing time release nuted soils? I've never seen that turn out well...

True dat Vostok, yeah I knew it.

I guess my point is you can't flush out encapsulated (time release) nutes with plain water. Well you can, but it would require a 100 gallons of water for each palnt. But using a flush like Clearex, this will help break down the fertilizer if done well enough. Most plants do poorly the 1st day or two due to the over flooding of the root system but bounce back by the 3rd day. Indoors I even reduce the lighting intensity for a day or so to help reduce the stress on the plants.
