A lot of experienced growers never change resevoirs. http://forum.grasscity.com/hydroponic-growing/677575-does-bigger-rez-mean-more-nute-overall.html When you're new its probably advisable. Once a week change out water/nutes etc.... monitor PPM/PH, see if it goes up and down. PPM If it goes down it means your solution had too little of nutes. If it goes up, it means you had too much. (Water is getting evaporated/used but not the nutes) As for PPM, heres a decent basic chart Reliable ppm chart for marijuana?? Seedlings, Early Sprouts 100 to 250 Early Vegging 300 to 400 Full Vegetation 450 to 700 Early Blooming 750 to 950 Full Mature Blooms 1000 to 1600 Note: EC Calculations are different, here's a conversion chart : heres a great chart that shows how different PPM can be from meter to meter... EC is the only real universal language... Remember to discount the ppm of your water. Nute lines that people like. General Hydro (even available on amazon!) Advanced (can be pricey) House and garden.
If you have flora nova laying around, for sure use that, and honestly, only that ( the bloom solution mainly) I used flora bloom in many hydro grows and never replaced water. i only added back water that the plant had taken. so in a 5 gal bucket, typically there is about 3 gallons of water. in one day my plant would take in 1 gallon of water, so the next day, i would simply make 1 gallon of new water (ppm'd an ph'd right) and add it directly back into the res. simple, easy and effective.
