Gaining Elevation

You start to feed the plant when the cotyledon (false rounded leaf that are the plants nutrient start to yellow) you can use 1/4 of strenght around the end of second week under 200-250ppm around week 3. Week four is were it actually starts. The cotyledon are usually gone and the plant is in its first week of actual vedging

Honestly a lot of what is in the water can and will be uptaked by the plant.. So it's a lot harder to balance out a "balanced" nutrient feeding if your water is rough... Aerating and all that jazz will not change the amount of TDS in the water.. Water is such a huge part of the total puzzle.. Like water + light + a little bit of nutrients = growth.. It's really hard for me not to recommend you getting an R/O system for yourself.. As growers spend a lot of money on our growing efforts or can.. And if your gonna be spending money... Then you should be willing to spend a bit more... Your plants will thank you... Your overall results can improve and your lungs will thank you as well. Good Clean water is a such a key ingredient to the end results.
