Leaves Curling Up?

my leaf edges on my plant are starting to curl up but a little unsure why?

my soil I use is normal all purpose...

Temps are between 27-33 degrees

Nutes are bat guano and tomato feed which has a NPK of:

4.5:3:9

I am using a 250 watt hps about 10 inches away from plant.


Please Help

I also forgot to add aswell, leaves look really healthy and so does plant but the bottom part of the plant is fine, whilst the top half there is leaves curling up.

Your temps are too high, and what you are describing sounds like heat stress. Do you have any pics, to help confirm this?

What is your airflow setup like? Do you have proper extraction? Also, do you have an oscillating fan or similar, to circulate air in your grow area?

I have a 18 inch High Velocity fan and I also have a carbon filter & Extractor kit that still needs to go in there but haven't got round to put it in yet.

Sorry can't post pics yet

Even tho I have a 18 inch high velocity fan, I think it's just circulating the hot air around the the room

27-33 degrees? thats freezing. do you mean celsius?

I'm pretty sure the OP was referring to celsius, obviously.

That sounds about right, given the temps and plant symptoms that you described.

I would make installing your extraction a priority. That should sort out this problem and give your plants a more comfortable environment.

Good luck with the grow.

yea hes right. your issue is not REALLY the nutes, its the circ. but def chill on the nutes. dont go nuts. the plant will let ya know what she feels. only add more when you know that its good to add and when your are in the process it feels right in your gut sounds odd but fore real, they are yours so get to know them

move the light up and get fresh air. dudeman above is correct. also, be sure your ph is dead on......why not......it makes them better. the better ph.....the better nute intake....
