Switching to 12/12 Flush or No Flush

The below has a ton of good guides and info.......

Marijuana Growing Guide Free Library

yeah I will search through that but I have before and Im pretty sure that flushing is not covered...... thank you though, I may be asking a little too much but Im kinda looking for some personal opinions on this one thanks to all in advance

Personal opinions....... Mine is that it's always a good idea to flush when changing cycles. I'd let 'em go a couple of days on straight h2o and readdress your concerns from there. If the same problems are still evident, dig further. If not, proceed as you normally would.
Hope that helps.

Hiya Graf,
You can change the nutes the instant you switch to 12/12. I personally have never flushed for a week prior to switching, and haven't experienced any difficulties afterwards. MaryJane is a very hearty weed, but when you switch, go with the 1/4 strength nutes and work up again like you did for vegging. Any time you see drastic color change check your pH. Get it right and give it time to take effect. Color should get right again. Sounds like yer doin ok g'luck

if Im switching in 1wk I should flush now then right??? and should I just run tap water through it or should I

1. fill the tub w/ water...

2. ph the water...

3. put the buckets in...

4. let the water rise to the top...

5. let drain all the way... (this is what I was told)

just flush alot of water through the plant, let it all drain out, and flush again.

It also seems that 1 of my ladies has a slight issue as well, the top quarter half of her is a way lighter green then the rest of the girls(almost yellow), and her newer tips seem to curl a little.

Im guessing nute burn. Im not really sure of the effects of over/underwatering so it could be possible i guess. Does anyone know the signs of over/underwatering?? droopy leaves I know, Im sure there is a more specific way to tell and thats what Im looking for.

1 more thing, any precautions to take while flushing or afterwards???? I really am bent on doing this because Im scared they will be over watered afterwards, or am I just paranoid??? PLEASE HELP ME!!!!

1 - the reason why u should flush is that by flushing ur plants u prevent the salt build up in the grow medium (in ur case i assume it´s soil)...ok so whats to do:
1st - water with about twice the pot´s capacity (1gal pot = 2 gal pH´ed water).....ALLWAYS CHECK THE Ph...something around 5.5
2 - after u flushed all the pots make ur flower nute mix and water ur plants...MAKE SURE U HAVE EXCELLENT DRAINAGE
3 - Flush and feed as soon as u start a 12h light cycle
4 - Don´t feed the plants at full blast start 1/3 or 1/2 strenght...the plant prob u have i sugest u start a new thread dude or else its easy to loose track...Peace

does anything drastic happen afterwards?? droopiness?? color??
