They may not have felt qualified to say anything as there is not an obvious problem from your original post
We all have bad days, hopefully yours will get better after a good nights sleep.
Give us some new pics in the morning, if the problem is more pronounced we can dial in the problem

Mean'- temps (alone) are not high enough to cause the curling,... your RH is pretty high as well,... the fans are blowing on them gently? Sometimes, a combo of higher T's, low RH, and too much breeze can cause heat/water stress on the leaves, but honestly, the conditions you've mentioned don't seem right to cause this IMO,... this type of curling can occasionally happen due to earlier stress during growth, or even rarely, something genetic,... More pics, whole plant, and another c/u would help... ditto for the branch "roll over" too... I see no signs of nute' burn or other such issues... ..**.. That said, help comes when somebody can get to it, and sometimes that's not immediate...this is all volunteer, after all,... and views are one thing, people offering quality insights are another... it's not like your plants were in dire straights, unlike many others here,... If you want potentially faster responses, post up in the Live Help Thread.... https://www.autoflower.org/f164/afns-live-help-thread-staff-only-replys-30723.html

Wow man you are one stressed person relax the plants look great some funcky leaf growth is not something to get so stressed about they look lush the temps are at 78 watch the ferts bro let them dry out abit before feeding again
common heat stress. The leaf will do that (edges pointing up & leaf starts to close) to conserve water as the stem cannot carry enough in-time to replenish water content in the leaf and thus it's doing that to defend itself so it does not loose any leafs due to dehydration.
Raise your HPS further away from the plants, at least 2-3' as soon as you can and report in 24 hours to see whether it's changing back to normal.
It can also be;
1. pH levels (you want a good pH level for coco) make sure to check both the pH of the water you water it with, and the pH of the run-off to give you an idea of what the actual pH is inside the coco medium.
2. Underwatering.
3. Overwatering.
4. Not enough air-exchange in your grow area.

Well I raised the light to 3 feet and turned light down to 500 percent they seem to have stabilized branch returned to normal some leaves that looked worse are a bit better I'm wondering if I should get rid of Mh and install multi spectrum hps starting to see white hairs which are sex hairs at intersections I read Muddy saying wait 5 or 6 weeks before switching to bloom nutes sorry for the stress but I'm handicapped just quit man made Meds after 5 yrs so I'm a mess due to opiate addiction and I need my weed keeps pain in check again sorry

You are on target with the nutes.
If you want a bigger yield, what until upper growth stops to start bloom nutes.
If you want faster finish, start bloom nutes at first signs of sex.
You could switch the lights if you want.
PS. kicking sucks, been there, done that-many many times- try not to take it out on the people close to you or the people you are asking for help from, it makes things go smoother when you are over the hump.

Welcome to AFN. Forth nine minutes from your first post to this one. To expect help in that short of time is unreasonable and getting an attitude about it is unacceptable. Diagnosing plant problems is the hardest thing we do here and requires experience. Not all our members and moderators have that experience or perhaps the confidence to tackle these type issues. Many will stop by threads in the Infirmary to see what is being discussed so they can learn themselves. You will find the people here to be incredibly helpful if you can the bad attitude. No one wants to help someone who is on a constant bitch. Just human nature. I have empathy for your health issues but please don't allow them to influence how you conduct yourself here on AFN.
On to your problem. Leaf curl, as discussed already, is often a sign of excessive heat. Where are you measuring the temperature at, the top of the plant canopy? That's were it should be taken. It looks like you have your thermometer set lower, so the temps at the plant tops could be higher. Leaf curl can also be an early indicator of a possible potassium deficiency. What nutrients are you feeding, how often and at what strength? Also, are you letting your pots go almost completely dry between watering/feedings?
