fan leaves curling in?????

hi, my plants are about four weeks old and looking healthy, they are in canna soil under a 600w. when checking them today i noticed that the larger fan leaves are starting to curl in along the sides, does anybody know the reason for this???

Could be heat problem but sounds like a fert burn, id get a PH meter and if its above 7.5 theres your problem.

cheers bro, i plan to get one tomorrow

When you get a pH meter make sure its a good one. They cost more, but are worth it.
Keep your ph at 6.5 Check after adding nutes/etc.

cheers mate, i was thinking about getting this one, do you know if its anygood??

Comes with a 6 month gurantee. But says it will only last one year?

i ordered a Hanna ph and ppm meter. they are on the cheaper side and i hear they are damn good for the money. you can find them on ebay for 45 dollors for both shipped. but watch it there are 2 sellers 1 is in the states and the other 1 is on hong kong. i cant speak yet for the quality on it. i my self am still waiting for mine in the mail. i think its actualy at the post office right now waiting for me. got a thing saying i had 5 parcels at the post office. confused me because im only expecting those 2 items. Also i only paid the ebay guy on friday so i wasnt expecting to have them try to deliver it on sunday 2 days later....

The ph meter will change your garden for the better. Good Buy!
