leaf curl

[taphead]

some of my leaves are curling just a little otherwise the plants look very heathy. I am growing hydor I have a ph and tds meter levels are textbook temp 75 with AC plants are two and a half weeks from clones. I did a water change would the clorine from the water do this. The water I started with sat for a couple days before I used it. Can I use the same clorine remover I use for my fish tank. or is that even the problem. Any way here are my picks any help would be helpfull.

I think it's a mg deficiency,the chlorine should not be a problem,the gas disapates in a short time,do you use an areator in the res?if not they help quite a bit,nice grow....bonbon http://www.overgrow.com/growfaq/1111

Yes I do use a bubler. I am useing the floro series wich I assume would provide the mg nessesary. and tds level is 1300 ph between 5.8 and 6.5 water change every two weeks I use and ebb and flo system with grow rocks flood for 15 minutes every three hours still on 24 hour lighting

you can kick up the PPM to about 1400,you want the ph to be at 5.5-5.8,i think the mg is being locked out because of the high end of your ph level(6.5)use a ph down solution to lower it,and that should help....bonbon...p.s see the ph chart that i attached,it's for cannabis

I will try to knock down my Ph thanks for the advice.

In one of my books it said that when the bottom leaves curl up it is a sign of Phosphorus deficiency. I will look it up to get more info on it. It was saying it was called like the leaves are praying for phosphorus or something. Also, is it the bottom only or all of them?
