Amount of water/nutrients

this is probably a stupid ass question but I need to know to better understand how to feed my plants...


Ok let's say my nutrient solution calls for 1ml per liter.

Does it matter if I water my plant with a liter of water or 2 liters of water? Or 3 liters?

What I don't understand is, if 1 pint isn't enough to fully soak the soil/get runoff, should I still use only 1ml for 2 liters or do the "1ml per liter" and give it 2ml for 2 liters of water?

I'm growing Autos answer I have a tendency to burn plants.


Whether I give my plant 1 liter of 1ml nutes or 2 liters of 2ml nutes, is this giving my plant the same amount or would 2liters/2ml be giving more nutrients than using just 1liter/1ml?

I'm so sorry if this is complicated or if it doesn't make sense lol. I just can't put it into words any better than that.

Nutrients usually have instructions on the nutrient to water ratio, but it doesn't say what to do if you need to use more water.

Thanks so much in advance. I believe that knowing this would help me be a lot better of a grower, or atleast a not-as-bad grower =)

The feed rate is the ratio, so if you plants needs 3 liters and directions say 1ml per liter, you put 3 ml into 3 liters. Good luck!

And that is usually high for some, is why people say 1/2 doses etc. Big azz plant may want more.

Start with 1/4 ratio of what the bottles says, companies want you too use more of their product than what's needed, so 0.25ml too 1 litre of water and go from their, more easier too up nutes if your plant needs more than too overfeed which leads too bigger problems

Mix it up at the recommended ratio - 1ml for every liter. If your plant take 3 liters each watering then that's 3 ml of nutes in the water.

Now, having said that, I go by the PPM's of my feed, not simply what they recommend. I recommend getting a PPM meter, they don't cost much, I think mine was 8 bucks from Amazon. For young plants I give them about 400 PPMs, and as they grow I bump it up to 600 PPMs, and 900 PPMs in flower. That seems to work ok for me, I've not had any burn from that.

Often with nutrients, less is more.... the manufacturers usually recommend much more than they really need.

Awesome thx dude. I actually have a ppm meter being sent to me right now. I'll try it out doing it that way. Thx for the info

If you always burn them cut down the ratio a little, maybe put 1.5 ml into 2litres or even 1ml to 2litres and see how you go.

Young plants will probably not need that higher ratio of feed so start low and increase as they get older and their need for higher levels of nutrients becomes more apparent. ie increased speed of growth.

I typically try not to feed my plants any nutes for the first month, and then start at a quarter of the recommended dosage. And remember that it will probably take the plants about a week to respond in soil so if you noticed a nute burn it could be from a previous feed. Try a nutrient feed followed by two straight water feeds, it helps from keeping the soil from getting too "hot" and it gives you time to correct for the next feeding
