BIG PROBLEM WITH LEAVES!!!!

For some unknown reason the leaves on my plants are curling downward dramatically, like a claw almost facing the other way, the tips have turned a golden brown (worse on a particular node)and the bud is turning light brown(only on top though). I have recently brought the plants in from the outdoors due to a dramatic dip in temp and transplanted into pots. I have them under a 400w hps light, they were fine a few days ago, smelling very nice but now they look a bit sorry. is it something ive done or havent done for that matter. the setup is very amateur as i took the plants off a friend when they were on the brink of dying. at the moment i think it maybe the ph of the soil or a nitrogen burnout. i read a few posts on here that suggest they have been over fertilised, so i flushed them earlier with bottled water, only thing i could get my hands on as my ph tester isnt working.

any suggestions welcome.......thanks everyone:thumbsup:

Yu need to check the ph of your soil runoff.....you can get some very cheap liquid ph testers at the local pet store. I wouldn't try to get by without SOMETHING to measure it with.

thnx man, i thought it may be the ph was off, im buying a tester and more up and down solution today. also gonna buy new soil, have wanted to transplant these girls for days but too worried about the current situation. found yesterday that the previous grower of these had the top layer with good soil (bio bizz)but bottom is just crappy soil from his garden. in process of flushing at the moment, the bottom crappy soil was holding a lot of stale water so held a lot of the fertlizer for too long. aerated the soil and left it over night, the plants seem to have responded to that. well i shall test the ph like you said my friend, if its ok (big doubt)could there be anything else i should try.

thnx :thumbsup:

Sounds like you are on the problem to me. :thumbsup: Good luck. :)

I don't know for sure, But when I added a 400w HPS the temp. got to 90 deg. and a within a week, my leaves curled like a claw. I killed the HPS and went back to CFL and some leaves look better. I have no idea what the real problem, also PH was high 7 almost 8. I fixed that problem, maybe this is what is happing with yours.
I for sure am not the one with the answer. Good Luck.
