twisting/curling leaves, help!

the plants are about 3 half weeks, in veg. Last week noticed leaf margins were turning in, sort of like venus fly trap, mostly toward top of plant. have not feed in a week now, besides bat guano and water. Now all plants are showing similar symptoms and some are curling like rams head underneath, towardsd the bottom of the plant. The smaller ones are begining to suffer the most with some curling of the leaves, twisting, and slight discoloration towards the tips and edges. Any knowlegdable feedback would bge much appreciated, thank you so much.
What is your experience level? novice

.3) Reflector type?- enclosed reflector
.4) Is there a consistent fresh air supply?-yes but not much necessarlly from outside.
.5) Do you have an exhaust fan and a circulation fan?-yes
.6) What are the bulb wattages, kelvin ratings, and schedule?i have 12 plants under two 1000w bulbs, on a 20/4 sched.

Your medium:
.7) Specific brand and type of soil, (coco, peat based soilless...) and anything you've added to it.-Sunshine #4 organic soil, i use mexican bat guano 10-2-1 once a week.
.8) Size of container.-buckets are all around 12'' x 16''
.9) Did you use peat pucks (or similar) to root clones or germinate seedlings?- clones

Your nutrients and water:
10) Source of water? (tap, bottled or filtered) What's it's ph before adjusting?-tap, 6.8-7.8
11) Method of checking water ph. (ph pen, test strips, aquarium test kit...)-ph pen
12) Method of adjusting water ph. (phosphoric acid, white vinegar, hydrated lime, PH Up...)-earth juice, ph down
13) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule. feed once a week w/2tsp. root organics-.1-.5-.25, 6ml hygrozyme, tsp. epson salt, 1/2oz age old grow 12-6-6 and 5 drops lotus flower essense per gallon(one per plant)
14) How often are you watering between feedings, and how much per watering?-watering once or twice between feedings, every 2-3 days
15) Any additives or tea's? (Superthrive, CalMag, molasses, Mother's Earth...)-no
16) Are your ph levels stable, or do they fluctuate?-they fluctuate a little usually between 6.8-7.8
17) What is your ingoing water's ph? ...your runoff ph?-5.8-6.5, usually dont get much runoff after watering
18) Do you foliar feed? If so, with what, how often, and at what time do you spray?no

Your growroom:
19) Indoors or outdoors?indoor
20) What size of closet, room or hut?-aprox. 9' x 9'
21) What are the temps and humidity levels while lights are on? ...With lights off? temp stays between 75 and 85 tho has been a bit hotter in there(85-87) due to some changes., 35-45 humidity; around 65 deg. w lights off
22) Have you seen signs of insects in the growroom?there are bees! that is all

Your strain:
23) What strain are you growing? (Indica dominate or Sativa dom?)-blowfish
24) From seeds or clones?-clones
25) Is this an autoflower strain?-?

correction: using hps bulbs

why is there such a variation in your ingoing pH? i would quit with the epsom salt...and everything else for that matter. that's way too much crossbranding crap. just feed with your baseline nutes. when you are trying to fix a problem you need to eliminate ALL of the variables that you can.

what size pots are they in?

your temps are a bit high too. high temps can cause leaf edges to curl up as they are working their hardest to dissepate heat.

its hard to get the ph exactly the same, i thought anywhere in that range was ok. they are in 5 gallon pots maybe, like i said most are around 12''x16''.

Yes, you're absolutely correct. pH can fluctuate. Except just so long as it's between 6.3 and 6.8. You'll be golden.

i am continuing to have the same problems. I have not feed with nutrients beside N for two weeks. Do i need to completly flush them. Also i have read elsewhere the bending upward of the leaves would quite possibly be a magnisium deficiancy, tho that was not mentioned here... any opinions?? thank you for the help so far.

do you have any pics? is it the leaf tips, or the serrated edges that are bending up?

it is the serated edges that are bending up only near the top.. i have four plants that are smaller, they are the only ones experiancing this along with slight discoloration on the tips and edges of leaves and some twisting.. the smaller ones are a bit closer to the light as they are on a table.. to reiterate, all plants are experiancing the "praying" at the top, smaller ones have a few additional probs. i will try to get pics, thanks again

if the serrated edges are bending up it means your temps are too hot. 78F is ideal. this is your plant trying to dissepate heat. can't speak on the other problems yet.
