hey im usin nutes for the first time and am a little intimidated about it all. O before i frgt, can water sit too long? is it cool to use water from a jug thats been sitting for like 2 month's? when do i start the nutes? im using this chart ( see pic below) with the humbolt nutrients organic grow and bloom. do i just add the whatever ml to a gallon o water and use the same water till that gallon is empty then switch to another premade jug? and if you know, i just transplanted 1 girl and started another one by seedling, can i vegg them @same time? the girl is supremely stunted. was just in a window for first 4 months. just put under a 400 mh. she started to try to think about flowering just cause the season changed, but has been in front of a sliding glass door, and looks about 12 inches tall with just 8 sets of leaves, lol. sad but its what i got. i honestly dont expect her to survive. would adding nutes today help? damn i cant find the pic of the chart,

I'll try to answer some of your questions, but as someone else insinuated this isn't really the place for them; as this is advanced cultivation and your questions are quite basic. There is a newbie forum that has some semi-organized content, guides, plus links to more thorough information and guides. It helps to start by reading well-rounded general grow guide written by a qualified grower as opposed to random posts.
Can water sit too long? Water itself is probably fine sitting in a jug or container, but after adding fertilizer(s) (especially organic fertilizers) it should be used immediately and definitely not stored in a closed container for longer than 12 hours. In all likelihood it may even be fine after 24 hours, but eventually anaerobic bacteria is going to flourish in the fertigation solution due to lack of oxygen. We don't want to supply any anaerobic bacteria to our plants, and you'll know when a solution has gone anaerobic due to the horrible sewage smell.
You can start feeding whenever the plants are asking to be fed. Once the cotyledons have extinguished after a couple weeks or so, the roots will need to get their nutrients from the soil. The soil may have enough nutrition to carry the plants for another week or more; if not the plant will exhibit signs of deficiencies such as yellowing of the lower leaves.
If the seedlings have been growing for a while you can just go ahead and start giving fertilizer slowly. Start with 1/4 the recommended dose mixed with a fresh gallon of water.
Of course you can veg plants of different ages in unison, but seedlings tend to do better under fluorescent lighting for a week before moving under an HID light.
