Downside to fertilizing.

Hello. I'm slowliy beginning to dabble in fertilization, as I notice some deficiencies on my Amazon frogbit (kudos to Darrel, I don't know how to properly insert your user). This has led me to slowly adjust amounts, etc as I see improvement/algae. My question is the following: Once fertilizing, the downsides are only toxicity and/or algae outbursts, or are there more? I know some micronutrients can interfere with each other's uptake if there's too much of one, but I am only dosing macros at the moment. So, hypothetically, if I am dosing a certain amount, there's no sign of toxicity to livestock and algae is still under check, then I can up the dosing?

Thank you very much. I am sorry I can't provide much details regarding the dosing itself, I have urea (yes, very toxic potentially, I use very little at a time) and a common NPK (3 - 8 - 11, 1% Magnesium, and 20% humic and fulvic acids).

Edit: still missing some data. The aquarium is the one on my signature, a Walstad wannabe that just did not work fert-free. And I'm tired of waiting for it to do so. Small, emphasis on root feeder plants, some emersed, and floating Amazon Frogbit and (presumably) Spirodela Punctata.
 
Hi all,

Just type "@" first and then as you start typing the member's user name, as you type it will give you options, so as soon as I'd typed "@Jor" there were only two options for members, I chose @Jorge OPL and you are now linked into the thread .

Yes, you can balance your dosing with the speed of plant growth that you want.

I use lean dosing, but if I wanted bigger plants or faster growth I'd just dose a bit more. I only grow plants that are happy on <"petrol fumes">, but if I wanted to grow a <"turned up to eleven"> plant? I'd give it <"plenty of everything">.

cheers Darrel
