lighter green edges?

[shuggy4105]

hi all, need a little help with diagnosing this problem that`s affecting my complete grow(almost)
the leaves are dark green but the edges are a lighter green, like lime colour , leaves are "closing" in on themselves, almost folding up.
the leaves look as though they`ve got smaller and thinner.
i`ve never seen this before and don`t have a clue what it could be.
anyone have any theories or info on what to do next? help!

That's what hapened to mine the first week or two of growing... the only thing I changed to fix it was watering more when i watered, but waiting longer in between waterings, and I also moved my plants slightly closer to my lights. This stopped the folding in, but that lime color kept persisting, so I'm not sure about that part.

thanx man, these ones are real bad though. this is a new leaf on the pics, see how they "half" along their main vein, tilting up.....
i don`t have a clue what this is, maybe i need to move my light closer?(400w hps at 25-30")

wow folding upwards ..... maybe you need lights at the bottom too , mine did that till i got my flo..but they went downwards not up , watering is right too 3days is definetly best to wait till next water even though ive seen you say its not as good , has helped mine loads infact i'll take pics but the burning tips is cause the light/heat (open growroom every now & then the temp on little leafs wont be as harsh)

infact saying that , ppl say point the fan at the top of the plant which is pretty obvious in away .... not getting to the bottom is just making them burn (get it?)

my mind is playing tricks for my problems but i can answer others lol

It`s cool now man, sorted in the last couple of days. Problem gone....
think it could`ve been under watering in conjunction with over-fert.
After a few days of streight ph-balanced water,they all look great.
I went with fewer waterings, and more water being given at that set scheduled 3 day mark.
my soil used to dry within a day, so i watered everyday, this was due to the 400w hps, which produces vast amounts of heat. Anyway,due to this my gals got stressed out big-time , however they had good structure to them and a fan blowing 24/7.
I`m re-starting nutes again, going in light at first with "Baby Bio" NPK-10-1.9-1.4, after a week i`ll start on the high (N) feed i got, NPK-25-15-15.
things are deffinately on the up. although i think ( i`m not 100%) i can see the beggining of balls :chuck: :confused2: still not sure.:fly: :fly:
