Does Anyone Know Whats Up?

Heres some girls I have vegging,notice the older leafs discoloration,I never had that with my first lot,but then I probably watered them more than I should have,,now I water these girls in the 1liter pots every third day and older girls growing in 3 galon buckets get watered once a week.
Im thinking the leafs are like this cause the plant takes the nutrients out the old leafs for the new growth,but I just want to run it past you guys to make sure theres not a serious problem.
This girls a concern cause even some of the new growths affected,but I put her in to flower in old soil so I reckon thats the cause,I put her back in to veg and gave her fresh soil

And another,notice the old growth

u should have used some new potting soil or rejuvenated organic mix , as I do to restock the needed neuts. watch ur ph and let ur water sit open to evap the chlorine. they don't need much for the 1st 30 days and new soil has it.

So is this normal?Im glad its happening on my second grow cause had it been my first I would have been freaking out

first plant is showing serious nitrogen deficancy, it needs nutes, second plant is messed up from being reveged, it needs time. 3rd plant looks nute burned.
more info on your setup is needed, what are you using for soil and nutes? Also dont water on a schedule get a moisture meter andwater when it says your soil is dry completely

Im using normal seedling starter soil,Bio Bizz nutes and magne cal.Thing is,apart from the middle one,the other two are being grown the same as my first grow but as I said I didnt get any of this.The new growth is fine but its still a bit worrying.Theyre being trained too so its alot of stress for them,the middle one was mainlined for 8(I broke a stem so its now 6) and the other two 4,though theyll be getting mainlined for 8 too once they grow more.Theyre being grown under a 250w cfl

well i wouldnt say "normal" but yeah you can save it, id advise you to leech the soil if not using any nutes if you are then look into a chart for colour change in leafs, g'luck

you should be watering at least 2 times a week i think.
