Thanks for the replys;

actually 2 of the 5 plants are yellowing (badly) and 2 seem just fine, while 1 was just about dead (but the leaves perked up this morn.!!) I think this might have something to do with the strains? (G-13, Purple#1, and Papaya) I think the G-13 is doing ok but cant tell any of them apart really, (although they are definately different plants)

It has been 7 days as of today so going to flush the system and clean the tub out (lots of algae already) The roots seem fine as they are already sticking out of the pots on 4 of the 5 plants.....thus my dilema.

Using a water conditioner today and upping the nute strength to the recomended full Veg ratio.....if it dont kill 'em it'll just make 'em stronger, right?! lol

Would like to force flower ASAP but am unsure if cloning from stressed plants is a good idea(i'm sure its not) but since this is a first time thing maybe just be patient and and go untill can tell which plant is which.......(Purple #1 is sooo small and compact, but G-13 is sooooo good....but maybe too big for this system.....?)

Sorry for the long post and Thanks for any replies
