Multiple Problems: leaves curling upwards & downwards as well as rust colored spots

watering with a lower ph is a good idea...mad i didnt think of that sooner...thx

but doesnt the water have to at a certain ph level?? is water at a 5.5 ph safe to use??

no, its just so that the soil doesn't go lower or higher than the ph your after, but in your case that watering with the right ph water isn't lowering your soil ph enough, the only thing i can think of is to try lower ph water in hopes that it will drop you into the right zone.

what exactly is the right zone for the soil ph?

6.2-6.5...............

there are soil amendments to alter PH, I know lime does something to it, its in the growfaq, didn't seem to say anything else though.

lime raises ph and stabilizes (buffers). Water with the lower ph and it will help. Flush with a ph of 5. If your are at 7 and you want 6 water with 5. But I wouldn't reccomend a ph lower than 6.5 in soil. This watering with a lower ph has helped me out of the same situation you are in now. Good luck. There are soil amenments that will lower or rise ph. Look into it.

2jjs here, i'm a newbie , have a month old that was growing quick outdoors with lotsa rain water. had to tran to bigger pot . now i'm got spider mite, and rusty larger leaves. can i spray it with sevin like my tomato plants ? it's three foot and iused miricle grow potting soil. also when will it flower and what do i do for nutes? thanx for some quick replies. 2jjs

you should take your ppm down 1150 is high for veg stage im at 630 with hydro growing og sour og and gdp its plenty, when i flower im at around 1200 maybe a lil higher...

edit.> oops didn't read the whole thread

2jjs you can spray it with seven should be ok or you can get some neem oil form and home and garden center neem oil is an organic and can be used until the day of harvest should get rid of the spider mites....i wouldnt use miriclegro next time just plain organic soil with no nutes added that way you can manage the amounts that go into your plant, as for flowering it will when you start it on a 12/12 light sch. for nutes any hydro shop will have nutes and verious prices you can go there look at what they have and go from there if you cant find any by you than go online and order that way which ones you use are personal prefence i use vitagrow and some technaflora supplements and never have any problems......
