over-watered

could it possible be under water?

doesn't look it. leaves look twisted, puffy, and wrinkly. water by weight.

the last time that i watered the plants the leaves was drooping like it needed water, and then i checked the weight of the pot and it was pretty light.

what do you think i should do? this is my first grow so i'm new at this.

relax, first of all. work on your watering by weight. continue with grow. enjoy.

so what do you think my next feeding should be? should i flush?

no flush. and feed a little less. your new growth is bright green. a lotta N

what do u mean when u say a lotta N. That i should feed alotta N or that I am feeding too much N. Thanks for ur input by the way

If your soil Ph is 6.3 you leaves shouldn't be twisting,but they are twisting like you over watered with 7.5+ water/nutrients.You new growth is yellowing as if you have cold nights?
Have most of your stems turned or turning purple/pink?

less "grow" nute

they look like they just need a little bit of tlc a little bit more nutes and dont over water them and they will pick up if your temps asre what you say they are...

i have the same issue every once in a while. It can either mean that you are watering too much or that the plant isn't moving water through its roots and out through the leaves fast enough. Either way, it looks like an excess moisture issue. Cut back on watering... and turn a fan on. If you don't have air moving, the humidity of your grow room can be at 50% while the exact humidity at the canopy of your plans can be much higher.

I think that I am having cold nights, I will check the night temp and post that when I find out.

the plants that I'm having this problem with are headband strain and I think the the stems are naturally purple.

also my last feed I fed the plants only 20ml of ionic per 5 gal.

the green is nice. ive heard that the leaves curling is due to over fertilizing. i had this problem too and thats all i seem to here. some say dont worry. i just gave it straight water for a couple days and then put 50% nuts in for the past few days. i think its helping

its over fertilization

idk because the last feed was only 20ml of ionic grow per 5 gal, someone replied earlier bout cold nights which I believe I was having because I was having the duct fan blowin cold air in from the bud room into the veg room where those plants wit the leaves curling are, I didn't have the duct fan on a timer so it was really cold at night when the hps light from the bud room was off. I have it on a timer now, hopefully that fixes the problem and that its not a over fertilization problem.

Note: in the flowering room I have a duct blowin cold air in from the outside and a duct blowin the air out of the flowering room into the veg room.

What do you guys think?

lighten up on the N

It is not the nitrogen claw that you would get from over fertilizing. The hooking is definitely do to moisture. The light green color might be from N lockout... temps too cold?

Make sure your room is above 65 f. Let your pots get dry out before watering. Turn a fan on.
