Is it ok with soil grow to feed with 10ml in 2 LITERS of terra flores every day as long as the roots do go through wet and dry period,

what I am saying: is 10ml of terra flores in 2 liters of water EVERY DAY going to burn or lockout my plants or is it not too much and ok..

Tahnkyou!

This all depends. Many people who grow in coco coir water and feed every day, for example.

But, just because you give nutrients doesn't mean the plant is going to utilize them. Your soil/medium might not even retain them sufficiently. It might not hurt the plant to give a bit too much, but the nutrients may ultimately be wasted (more of some than others). In soil, half the story goes like this: negative electrical charges on minute soil particles (humus) attract cations, which are positively charged: such as ammonium (NH4+), calcium (Ca++), magnesium (Mg++), potassium (K+) and others. When a root hair wants to absorb one of these cations it does so by exchanging for a hydrogen cation (H+). On the other hand we have anions (negatively charged), including nitrate (NO3-) and phosphate (PO4-) which will not be retained by humus; they stay in solution and tend to leach from soil.

My point is that provided you have a good soil with adequate humus content the aforementioned cations should mostly stay put and remain available for use by the plant; any 'extra' cations should be retained. Excess anions on the other hand will just wash away (soluble nitrate and phosphate fertilizers).

Amazing how knowledgeable you are, I have shit soil that ran out of nutes and now I am tryig to get my plants to finish by feeding with the nutes, what I am to understand from what you are saying I can continue feeding with 10mm in 2L every day so I will carry on!

Thankyou!

does the company offer a feeding schedule? following my nute's schedule did the trick for me

Yes it does and I am following it but like most schedules they give you the ratio but no way of knowing how much of that ratio to apply making the schedule completely pointless so well done to them for that, not like I am gonna water my plants with 10L of water!

Well, the definitive answer is that no one is very likely to be able to give you a definitive answer. They would have to know the fertilizer in question, and be familiar enough with the characteristics of the soil.

But it basically comes down to CEC (cation exchange capacity), which is what my other post was touching on. Hydro mediums tend to have low(er) CEC. Rockwool and perlite for instance, have practically no CEC. There are no "exhange sites" on rockwool/perlite particles that hold onto cations like soil/humus or even peat moss would (to a lesser extent). Therefore, rockwool and other soil-less media need to be constantly supplied with nutrient solution because the ions don't like to stick around.

If your soil lacks humus, or is perhaps too rich in low/no CEC amendments it would make sense to have to feed more often. I've been contemplating this recently with perlite, which many people seem to use a lot of in their soils and recommend that others do the same. In some cases folks are recommending that others use like 20% perlite or more in their organic soil mixes. But the more perlite you use the less nutrients the soil can actually hold, and apparently it means less places for microbes to colonize as well.
