Flower stage lagging, can I add nutes if it hasnt ever had any ?

Good afternoon !

I am growing an outdoor Hulk Berry strain. All natural for the most part, its planted in a premium potting mix blend from the start. Tap water for feeding.

A couple friends of mine have the same strain and they're flowering sites seem to be well ahead of mine. Granted they may get 2 hours more sunlight a day I think due to my balcony positioning but I still seem to be way behind.

One friend used miracle grow liquid fertilizer but I've heard that's not really good for cannabis.


Can anyone recommend a good nutrient or fertilizer that I can buy to help give it a nice boost ?

I'm relatively new to growing and I wasnt sure if you can introduce new nutrients or fertilizers midway into flower.

I am in Toronto, Ontario , so getting worried of the cold to come in October and I really want this baby to finish in time.

Thank you as always for the help everyone!

I have 3 plants of the the same strain. One is lagging behind the other 2 by a lot. I would say a full 2 weeks behind on budding if not more. It seems some plants just take longer. I'm going to say you cant force an outdoor plant to flower by bumping the nutes.

I've used MG tomato food for veg and now MG bloom for budding. Salts are salts and they are 8 feet tall and look great....except for the powdery mildew I'm fighting. ...which sucks

Ah man I know the struggle with PM I had that on my first grow last year ! I used potassium bicarbonate which seemed to work pretty well after a couple of spray treatments. Have you tried that?

So do you think if I started introducing a product similar to mg bloom designed for the flowering stage that it wouldn't burn it or cause damage ? Someone recommended i try work casings and something else but I just dont want to over do it and then stunt her growth or something.


Thanks for the feedback bro and Goodluck with the PM!

MG Bloom is fine. Use it at 5ml/gallon and it won’t burn.

I've actually read to much of one nute and not enough of another actually locks out nutrients. I think next year I'm just going to try a balanced fet like 20-20-20 the whole grow and see what happens. I have a feeling it will just as good as a 10-20-10 type fert. Will be a good test

I just realized I have this from last year , could this be used during flower?

It shows 18-18-21

Or should I buy something different ?

In a pinch i guess,what you needed to do was re amend the soil about 2 weeks ago or maybe nothing lol.How does the whole plant look?What you can do next year is start covering your plant say July 30- August 10 ish.This will speed up the flowering 10 fold.So 7 pm every night till about end of august.Then 7am take cover off. A bit of work but makes a big difference.Cheers.
