A question from a fellow grower:
I have all plants on light 24/7 , there is also Organic miracle grow, how much should I use?
In my experience, the plants need some period of darkness. Think of it as resting time, or sleep. Their genetics were evolved under conditions of light/dark/light/dark. I would agree with Robert that 20 hours is a good day for Autos.
The Miracle Grow - start off using 15-20% of what the package says. M.G. is great fert., but it is very strong (i.e. ‘hot’). This iwll seem like a ridicuously small amount to use, but take my word for it. I’ve been growing since the late 70’s.

I agree with Jodie about your photo period. I do not know why people want to attempt a grow and never rest the plant.
I am sure that MG is fine, but the way you held the bag, only 1/2 of label was readable to me, 9legally blind) nede PDF. Anyway; You may need some micro nutrients or other essential minerals or chelates in order to get 100% out of the plants, but it should do the job.
Now Jodie said use a small amount of recommended dosage, and I agree with this too; To an extent. If the bag has a listing for seedlings, then I would look at that before I just customized the formula myself. With that said. Always follow directions on the bag. If you need to lower the mixture ratio then do it; And for seedlings, It is always a good idea to use the philosophy that “Less is more”
One final note. It is hard to make an informed suggestion with out the proper info.
- How old are plants. Makes a big difference.
- What are you growing in? Does the medium that you are using contain nutrients already?
How are you checking the PH of your runoff?
Good Luck
