A little worried about my plants. flowering day 16, Take a look.

Hello everyboday.

So i'm a little worried about my plants.

I'm 16 days into flowering and they are going mad. growing so fast I can hardly keep up.
Buds are are starting to form, (Or at least the places where the buds will be)everywhere. and in genral They look great.

Except, A lot of the leaves seem to be curling in a bit.

Now I'm gessing I over did the fert.
When I put them in I was aiming for EC1.3 and ended up at EC1.4 (Which is about the Max reccomeneded does from Canna).

The plants seem to be drinking it fast, and over the last few days the EC as dropped quicker than the water I have added.
What I mean by that is, I have been adding plain water which is lowing EC but also the plants are eating the nutes as well.

The E.C has dropped 0.9. in 4 days.

Am I okay? I think I will make my next rez up a little weeker maybe aim for 1.2 including some PK3/14

I'm not seeing any Nute Burn which is good.
I suddenly have a heat issue,, The room has been sat at 22c for weeks and now it has jumped to 25c and a plant at the back has a few burn marks on it.
I think there are two resons for this.
1) The weather has got better and it's just warmer
2) The plants have gotten so big that my desk fan is not powerfull enough to keep addiquite air flow.

Any way I am rambling. If you read all that, thank you.

Take a look. This is the worst effected leaf, but there are a few now.
I will be happy to answer any quetions.

well you have to figure that by changing your like schedule to 12/12 you basically told the plant that its season is about to end. So now, its focusing more heavily on making the buds, which if you were to pollinate would make seeds (to keep the species going) but regardless that they are un-pollinated, they are still focusing mainly on making buds as opposed to keeping their leaves looking super awesome.

okay. cool.

So I just need to relaxe.

It's my first time.

Thnaks for the reasurance.
