Spraying Cannacure and CalMag water during Flower?

I have a SLH autoflower on day 61 from sprout; it's my first grow. I've been spraying her with Cannacure once a week as a preventive measure. It says completely natural on the bottle and to use it until harvest. But I was wondering if it's bad to spray the plant during flower? It also comes on to the buds when spraying, I don't think it will harm the buds but I'm worried about the taste.

The same question also applies to CalMag water; not lately but I was spraying her with CalMag water everyday. I've been thinking about doing it again but I'm not sure if it would be bad for the buds. Thanks.

I never foliar spray during flowering it’s asking for trouble.

personally I only use a small amount of spinosad and neem oil during veg before going into flower. Then it’s just make sure my sticky traps are sticky lol.

Calmag is best to foliar feed for a deficiency when you need a quick fix and certainly shouldn’t be used on the plant itself during flowering

Ok thank you. I sprayed her yesterday with Cannacure but I won't do it anymore. My humidity was a little bit high and I thought it would help with possible mildew and pests. And for the calmag spraying, I had used it during vegetation a lot and got the benefits and I'm seeing some bronzing on the edges of some leaves and stems now, thought it mght help.

You should not be spraying anything on flowering plants.

This is what gets me about these companies targeting products to cannabis growers. They can say it can be used up until harvest but that doesn't mean you should. Anything to sell more product.


"CANNACURE provides the leaves with a second natural skin, that makes it impossible for pests and mildew to function properly. This skin forms a sticky layer which controls plant pests and makes sure the plant is able to breath."

Listed ingredients:
magnesium, iron chelate, manganese, sodium laureth sulfate

It probably has unlisted ingredients as well and who knows what those might be.

I don't know about anyone else but I don't want something that forms a sticky layer of residue on my buds. It may be fine for use during veg but to say that it can be used up until harvest is ridiculous. Who wants that on their buds? Especially the sodium laureth sulfate.

I'd stop spraying that immediately and only use it during veg in the future.

Thank you all
