HELP! 4 Weeks into Flowering, DROOPY LEAVES

Here is a long post with lots of info, please I need help badly. I donâ??t know if the girls are in shock from treatments and temperature changes â?? I wish I could post pictures but I canâ??t yet. The leaves are droopy (claw and canoeing) and are yellowing. Some are drying up at sides and tips, and have brown or yellow spots on them. They have beautiful flowers!!! Full of trichomes and red hairs, super sticky. Iâ??m a little worried about mold. We have had trouble controlling humidity and we got some powdery mildew, we sprayed once with an organic solution and will be spraying again tonight, PH had been fluctuating, more info is provided by me answering the questions below:(. Please help! We want to know if we should dry them out now or get them healthy again and then dry. Please Please help, We are very worried about our girls!

What is your experience level? *First Timer*

Your Equipment:
.1) Type and wattage of lights. *HPS 1000 Watt*
.2) Distance from tops? *18-24 inches*
.3) Reflector type? *enclosed reflector*
.4) Is there a consistent fresh air supply? *Yes. Recently we added an air conditioner unit that can be switched to a dehumidifier, it pulls in air from the outside, we are currently using as a dehumidifier*.
.5) Do you have an exhaust fan and a circulation fan? *Exhaust fan sort of serves as circulation, right now we have a fan pushing air out of the room, and our dehumidifier is pulling air into the room from outside. We will be setting up a proper venitilations system, we are connecting a inline fan to our light and connecting ducts to otherend and leading to vents in ceiling to pull air out of room, pull heat from light, and into the ceiling*

.6) What are the bulb wattages, kelvin ratings, and schedule? *They are on 12/12 and 4 weeks into flowering (Green Crack and Super skunk)*

Your medium:
.7) *RockWool placed in Hydrotin Drip System*
.8) Size of container- *Reservoire that holds 17 gallons and 8 one gallon buckets*
.9) Did you use peat pucks (or similar) to root clones or germinate seedlings? *bought clones*

Your nutrients and water:
10) Source of water? *TAP*
What's it's ph before adjusting? HIGH 6 - 7 Use PH down to adjust as well as plant nutrients
11) Method of checking water ph. *PH/PPM meter*
12) Method of adjusting water ph. *PH DOWN and Nutrients*
13) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule. *1350 per gallon for bloom formula, and 1750 for grow formula per gallon of FLORA NOVA; 7-10 days feedings, closer to 7 now*
14) How often are you watering between feedings, and how much per watering? *drip system, on 24/7*
15) Any additives or tea's? (Superthrive, CalMag, molasses, Mother's Earth...) *NO*
16) Are your ph levels stable, or do they fluctuate? *FLUCTUATE, Have been trying to control with PH Down*
17) What is your ingoing water's ph? ...your runoff ph? *in going is 5.33 ; Just checked runoff â?? it is a little high 6.6 just adjusted PH in resevoir hoping it will fix the rest*
18) Do you foliar feed? If so, with what, how often, and at what time do you spray? *We haven't been, should we*

Your growroom:
19) Indoors or outdoors? *Indoors*
20) What size of closet, room or hut? *Room is 10x14*
21) What are the temps and humidity levels while lights are on? ...With lights off? *temp gets to about 78 during day and 65 at night, humidity levels have been very hard to control. Last night they reached 80%! We are trying to ventilate better and are now using a dehumidifier, which seemed to work well at first but now it isnâ??t. UGH*
22) Have you seen signs of insects in the growroom? *Yes, we believe they were fungus gnats, tiny black bugs with wings on plants and in roots, we sprayed with an organic cleaning solution purchased at hydroponics shop and put up yellow sticky tape, it seems to have controlled the problem. We had a situation with powdery mildew and we sprayed with an organic solution to control that as well, we are desperatley trying to get a control on the humidity levels as well*

Your strain:
23) What strain are you growing? (Indica dominate or Sativa dom?) *Sativa dom. (Green Crack and Super Skunk)*
24) From seeds or clones? *CLONES*
25) Is this an autoflower strain? *???*

The claw/canoe leaves tell me you are using too much fertilizer in total. The PH fluctuations may be part of the problem. I would try use less total ppm and control the PH a little closer but I am no expert.
I have never seen powdery mildew and fungus gnats in a hydro setup, only soil. Do you have both together by any chance?

Whatever you do, don't chop em. Get it figured out.

OK - here are some pictures, not very food quality pics, taken with phone camera. For some reason the lights make black lines in the picture?? Might have to try to post this a couple times to get it to work.

Here is a link to the pictures, that might work

I actually only am using a hydroponics system, no soil.

I'm not really that internet saavy but that link looks like a word doc saved in hmtl, which i believe would only work on your personal computer.

either way that link doesn't work :(
