nirvana bubbleicous 3 weeks flowering!! smaller leave curl

ok I have 2 female nirvana bubbleicous plants now in their third week of flowering...Running ebb and flow with a 250 watt hps using full lucas formula with RO water + about a teaspoon of epsom salt with a 6 gallon res at 1000ppm with .5 conversion factor. Temps are 77f with lights on and 72f with lights off. flooding every 3 hours for 15min with lights on and no flood with lights off. problem is the smaller fan leaves are curling under like ram horns big sun leaves are nice no curling but also not getting alot of flower production no sure whats going on?? can someone please help me with this...big thanks ahead of time!!

if these are autos they will take a bit longer to flower...IMO u should let them veg for another 2 weeks before putting them into flower...they dont look ready

Looks like a little heat stress. Your temp may be 77 down by the hydroton but it's probably 5-10 degrees hotter at the canopy. You're also flooding a bit too often, try cutting down to every 5-6 hours.
Do you have room to move your light up? If not, you should flower soon or you wont have enough vertical space.

Im already in my 3 week of flower and I have no more room to raise it I have also taken temps at the canopy and the hottest I ever seen it is 84f but its not the top leaves that really have a problem its the small growth that in the middle of the plants? I have already kicked back the flooding to every 4 hours so only 3 times with lights on and no flood with lights off...I am also using h202 at 3ml per gallon and have a diy carbon dioxide generator with sugar and yeast...

No there not autos and I vegged. For 3 weeks but had to flipem due to my height restriction...stealth grow cab

clawing is a traditional sign of too much nutes, you can see a few of the fans doing it also at the tips. cut the nutes to 750-800 and see how they do, remember the affected leaves will stay that way, pay attention to new growth.
