Progress report W/pics...Am I in trouble?

OK, I am at day 26 of flowering my 3 remaining plants. The strain is called peak-19 and Here are some pics of where I currently stand. I am am currently water them for 15 mins on and 15 mins off throughout the 12 hours that the light is on as this is what was recommended to me by the guy at my local hydro store. Some of the leaves around the buds are starting to worry me as they are curling up. The Ph is currently at 6.0. Currently I am only using Sensi bloom part A, part B and sweet leaf. Pointers on making them better with whatever time I have left and over criticism is welcome. This is my first grow and I have learned a lot so my next batch should be better. Thanks in advance guys...

ur gonna have some big ass colas. looks like the HPS is getting a little warm in there, what are ur temps like?

I remember skunkushybrid saying u can keep ur bulb pretty close to the tops of ur plant as long as U have a fan blowing the heat between the tops of the plants and the bulb.

whats ur setup for ventilation and air extraction?

Its about 75 degrees inside the room. I have a fan blowing on wall next to the plants pretty hard and it ventilates the area pretty well. There is also an AC mounted in the window which pretty much allows me to get the room to any temp I need it at. Is it normal that the leaves around the buds are curling up? They are sort of hard and curling as you can see.

No one can help?

Hi there,
I don't think you have much of a problem there. From most of the pictures I have seen of indoor growing, the fan leaves do start to curl. I am not sure if this is normal BUT your plants look healthy. Perhaps you are worrying for nothing.
I think your crop looks f-i-n-e!!!!!!!!!!!

Maybe slightly to hot and slightly over nuted and slightly over watered but overall the majority of your plants structure looks good just some tip stress,try to lower the temp by a couple of degrees water very slightly less and maybe a very small amount less nute

Yeah looks like a successful grow to me so far, good job! I'd back off on the watering just a tad and see if it makes your plants straighten up.

Thanks guys encouraging news here. Glad to know I am not doin so bad.

Anyone have a ballpark estimate at what my total yield might be like from these three plants?
