LV_Kid said:This is very common and normal with both fng and fnb.. With the high levels of nitrogen and sediments. The best thing you can do is put a pump in your reservoir to keep everything mixing constantly. Always make sure to shake the hell out of your bottles before you pour your measurements. This is the price you pay with having a one stage nutrient system.. This actually caused me to switch to a two stage new from how messy it becomes. I have had excellent results though with both. What system are you running this through and what strain?? What dose are you feeding them??
LV_Kid said:Sensi Star is an very nice strain. I've seen alot of people have great success with it in ebb and flow. Your dose is right around what i was feeding, keeping my ppm at roughly 1100. I thought of the same thing bro, a painter mixer for that shit would be a good investment. This kept me from ever buying the bigger bottles such as gallons. I always buy mine by the quart considering how much easier it is to shake.
After you put the pumps in your res you should be fine with the nutrients staying completely balanced and well mixed.
Do you have some pics to post up??

2- and 3-Part Nutrients
Most 2- and 3-part brands provide adequate levels of macronutrients and trace elements. The 2- or 3-part packaging format is often deemed necessary by manufacturers to avoid stability and compatibility problems between certain nutrient species when they are present in the same bottle. As such, the nutrients are strategically distributed among each part. Most important, the calcium is kept separate from the sulphate and phosphate (i.e., in a 2-part, calcium is normally in part ‘A’, whereas sulphate and phosphate are in part ‘B’.)
1-Part Nutrients
As indicated in Graph 1, when created in the form of a slurry, a 1-part product is actually able to provide superior levels of macronutrients compared to 2- and 3-part nutrients.
1-parts not based on slurry technology, however, are typically deficient in at least one macronutrient. This is due to the difficulty of formulating a product with concentration equivalent to 2- and 3-part nutrients while still providing a complete balance of all necessary macronutrients. The main problem is accommodating sulphur (as sulphate), because in meaningful quantities a precipitate will always form (see Fig 1). This is due to calcium’s affinity for sulphate, which results in a precipitate of calcium sulfate, (CaSO4). (Note that in 2- and 3-part products, calcium and sulphate are kept in separate bottles.) The 1-part precipitate is usually in the form of either a heavy sludge that cannot be homogenized to enable a blended dose to be poured, or a crystalline precipitate that can be neither homogenized nor easily dissolved.
To avoid the sludge or crystalline precipitate, most 1-part manufacturers either eliminate all sulphate from the formulation or reduce the overall nutrient concentration, particularly the calcium.
Slurry
As mentioned, all of these problems can be overcome by employing slurry technology. The slurry is a suspension (of mainly CaSO4 solid) within a solution containing the balance of necessary macronutrients and trace elements. It is shaken just prior to use and remains homogenized (i.e., blended) for sufficient time to dispense a uniform dose (see Fig 2). Once the dose is added to water and briefly stirred, the CaSO4 suspension dissolves immediately. The use of a slurry therefore enables the nutrient manufacturer to exploit the solubility limits of calcium and sulphate and to actually squeeze more nutrient species into a given volume than what is possible with the standard solution technology used in 2- and 3-parts. This type of 1-part nutrient product is represented in Graph 1.
ItsGrowTime said:The sediment at the bottom of the res is humic acid in Floranova that has fallen out of solution. Im no chemisty whiz or anything but I understand it to be humics that have binded to other elements and are no longer able to be consumed by the plant so they settle at the bottom. Either way, it's 100% normal.
MPL said:I've actually got bits floating around in the res. I haven't noticed any build up on the bottom yet but it has only been a few weeks. Not that I can actually see the bottom. lol
MPL said:lol Nope, no AN.
Umm, the only other thing in the res is SuperThrive.
6.5mL/gallon of FNGrow, 1mL/gallon of SuperThrive. I only apply the SuperThrive once, then I just addback with the FNGrow.
ItsGrowTime said:Sounds like it's just the humic sediment I mentioned before getting kicked up from the bottom so it can't settle. I see it in my mother DWCs all the time with FNG.
