Grand Daddy Purple first grow, feedback/reactions welcome

Learn what you can from this. Its my first run and I've made plenty of mistakes. This is an in-depth synopsis:

-Strain: Grand Daddy Purple, uncertain if Ken's
-Indoor
-Week 7 of flower
-Grown from seed
-Deep water culture, reverse osmosis water, general hydroponics Flora Duo with Cal Mag supp and Vegan plant -booster
-Commercial air pump
-Strong ventilation
-High temps 70's to 90's
-Two plants, started with 6
-Vegged them for 8 weeks! under two 90watt UFO LED with two 65wCFL, flowered under same with 600wHPS also...these girls are large. Pic attached was at day # 42 flower, currently day 46.
-More info to follow

My list of mistakes:
1.) Had a bad ph meter and was attempting to fix a problem that didn't exist x 2 weeks ...dumb!
2.) Used multiple girls in one tub and then vegged for 8 weeks. I thought this was really smart. Well, when three males appeared and another one was just plain messed up, I couldn't pull the roots out of the reservoir because they were all tangled together in a giant mass...8 weeks of vegged roots! Boy was that a bad mistake. I eventually pulled the stumps and got them outta there.
3.) Exposed to excessvely high temps and two bouts of lockout. One top got a little singed right at the top but now its morphed into this three-pronged mutant bud!
4.) Didn't lollipop enough during veg. Gonna have lotsa popcorn.

On the bright side:
1.) I've got a big donk, 18-20"
2.) I've got about 23 tops and they're just starting to swell
3.) Its almost done. Stress relief and yield are almost here.

Tell me what you think. Thanks. It's my first run, hoping for a pound cake LOL

This is the best overall image I can come up with, its so damn thick in there. This GDP smells like lemon and spice. At least for now.

How close do these look? I'm already in week 7...

That big one just dwarfs everuthing in there. That's because it cannibalized and consumed the root balls of three of its neighboring plants down in the reservoir. I named it Cletus even though its a female, cause its larger than life like my uncle Cletus! I mean the other colas are good sized like paper towel tubes but that thing is bigger than my HPS fixture!

Yeah that was probably a bad Idea vegging for 8 weeks with multiple plants in a single deep water culture reservoir. But after all those mistakes, it may just pay off in the end. Its like a miniature jungle in there.!

you have a 20 inch donk?

Lol no Cletus does

nice job looks great

Well the experts on this site have ruled out the possibility of this plant being Grand Daddy Purple. Just goes to show my own ignorance. It smells of lemon and spice, of that I'm sure. Another person said its sativa dominant, probably with heavy thai influence. When I looked up lemon thai, it looks exactly like the other bigger topped plant with ,many colas in the background. So I guess this is lemon thai. Maybe. What do you think?

Down below....There had been 4 others originally. Such was my ignorance. Good thing those turned out male. There would NOT have been room after 8 weeks of veg. And it was HELL trying to untangle those big root balls. A lot of the roots were eaten by the two girls you see here...cannibalized after they were cut. That ended up making the PH stratify into layers, unbeknownst to me. And I had a broken pH meter too that I hadn't realized. These factors added quite a few challenges.
