How often are you using the MG? Give it some fresh water and see if it doesn't perk up in a day or two.

thanx for da quick reply ,i did that 3 days ago ,and today i have water again only plain water ..am using my GM every week (once) any advise on what nut i can used for my gurl??

I hear Miracle Grow is pretty hot for lowryder. Lay off the nuts, they don't like much nutes at all.

So u mean i shouldnt give them anything at all??? except water!!!! how bout when flowering stage??

i would definately flush them and maybe add some espon or magnesium in about a week or so...

ok i will definitely give it a try and see what happen, thanx again to all of ur reply will keep an update for sure as it help a lot over here with u guysss...

1 more thing do u think adding 1 more 125w Eco light to my grow box would help for the 2 younger plant or it will b too much,as i dont have a well ventilated system yet???

here a pic of the box am growing with its 4ft L and 2ft w

it's nute burn
