nute defiency i believe, please help, pics

Okay so i noticed on one of my plants the leaves started curling under, and i researched it and decided it was a magnesium defiency, so i started giving (have only done it like twice) 1tbsp of epsom salt/gallon of water every two weeks.

well, the problem just got worse.
it's on several of the fan leaves on both plants now! as you can see in the first pic. the second pic is the healthy leaves, so you can see how bad they are curling.

Also, as you can see in the 3rd pic, the stems look very week and cannot support the leaves, i'm guessing this is because i don't have enough light?
i have 3 75watt cfl's and only two plants.

please help me out,
thnks.,.

anyyyyyyyyyyy ideas!?

the bending is the plant leaning towards the light, if ur limited on light move ur plants around to give them even lighting, if u think ur having problems wich it looks like u are, just flush ur plants!! are u using neuts? wot temp? humidity?

whts the best way to flush? just pour like a gallon of water into the pot? ha.
i should be in the NEWB section..

but can you plz fill me in?

Take ur plants to a bath if thats possible, flush with teppid(luke warm water) 3 times the amount of soil ur using, easy as that!! Ok mate?

Here is a hint for you from my recent experiance... Check your Ph, of the water going in, with nutes, and the run-off.

wont result in overwatering?

Heres another tip if ur using tap water, get a clean disinfected bucket and fill it with water, let the water sit for at least 3days and its a lot healthier for the plant then ok.

Thankyou blessamerica, why not pass on wot u now!! As long as the person recieving the help appreciates it init!! Its a good site wich will help u through ur whole grow!! And it makes it an even nicer experience when u speak to nice members as urself!!!!! Once again thankyou kindly friend.

+rep from me, since i haven't

one more question, this wont result in overwatering the plant?

or after the flush don't water for many, many days?


correct?

after flushing just leave the top 2-3inches dry out then water again!!as long as u let the soil dry out inbetween feeding ul b fine and wont overwater, never leave the plant get to dry tho as a thursty plant can cause neut burn if ur using neuts that is, BIG TIP: bye a moisture meter, very cheap and realy realy effective, saves a lot of stress and guesswork!
