Any Help would be much appreciated

Dose any one know what could be wrong with these plants.. ? thought it could be overwatering but not too sure and wanted some opinions ?

OK im growing in canna soil 11 litre pots.. using 2 x 600w HPS have been gradually introducing canna vega.. i have a 6" fugal outlet fan.. my tent is 1.5m x 3m x 3m i also have a 12" fan circulating the air inside and am relying on the intake of fresh air to be sucked through the 4 vents have the lights on 16 on 8 off..

I thought the problem could be to do with over watering as i gave the 11L pots 1Ltr of water when they were put in from the smaller pots... my humidity ranges between 35 lights on and upto 60 lightss off.. the temp is between 74 and 76 lights on and between 55 and 60 lights off ??

Wish i knew what was wrong with them, the middle one is yellowing so it might be lacking in nitrogen. But if you can fix your plants soon i think they'll be okay cause they would look great if they didnt have the droopy leaves

I think, from what I have observed in my grow, is that your young plants may be being exposed to too much light for such young plants. I used too have the same problem, until I created a seperate area for my very young plants using cfl's for lighting.

Think of you plants as babies. When very young you can not feed your infant adault food, such as a steak. You have too use baby food. Cfl's provide adaquate light for a young seedling, and its cheaper than those 600w hps you are running. I do not put them into mh light until their first transplant. As their first pot is 3 inches or so, this usually takes about a month from seed. After they are transplanted into larger pots, then they go into the mh and a regular light feeding schedule. I emphasise the word "light". Usually plants grown in soil should not need extra nutriants until they use up that which is in the soil, and more harm than good can be realized by feeding them nutes they do not need. I do not even start a steady nutriant regime until they are flipped into flower.

I hope this helps

hi guys, thanks for the response, i have another 5 which are flourishing.. have just switched to MH.. this inst the problem but wanted to veg with them... think ill let them totally dry out for a day or two then give them some fresh water.. may try switching one of the lights off encase it is too much light.. If any as come across this problem please let me know your thoughts..?
I will get some pics up of the others soon.

Cheers Again..
