Anyone find freakish plants from time to time?

Start by saying im not a newbie grower been at it a long time now. But im wondering if anyone else has has some freakish plants when growing? By freakish i dont mean mutants or such we all get that from time to time i mean has something umm wierd/unusual happen and all of a sudden you notice through flower this plant is not normal at all. Sure i have had some freaks over the years but again i mean the real WOW wtf happened and how do i do it again type? For me it happened once in the last couple decades and to this day im trying to reproduce it and have failed horribly lol. I had a 6 plant grow going nothing unusual at the beginning but had some strains i love in there like OG 18, Power Flower, Bubble Gum, Afie and Star Bud. All strains i grow and are in my regular rotation so i know them and the phenos pretty well(i do keep records). What i KNOW occured was in veg, at about 4wks in veg i had a issue pop up with a few of them. I fought and fought that issue with no apparent luck at all till finally it was time when i would have all ready flipped them but they were so bad off i was going to toss the three sick ones out but changed my mind since i had room so little to lose really other than the risk of a herm popping up. I tried everything to help them and the others were normal. I did keep them alive and to my shock and amazement at around 5 to 6 wks in flower they took off and were finally happy. They unfortunately were small plants now after all the struggles they had but as they went along it was real obvious something occured with them and they were the frostiest things i have ever grown BY FAR. Harvested them and omg wow hands down the best indica(og 18 one) and sativa(pf) i have ever grown or smoked. I gifted a lot of it to my friends and family just so they could try it and all agreed wow. Since i have racked my brain and tried and tried to do it again failing each try. Only thing i know is they had different soil mix i was trying out so i am pretty sure it is related to that, the original issue anyway i dont know if that caused the spike late in flower but it seems so. I had a little more of that mix so i tested and tested and still i cant really figure out what did it. Im starting to think it was a combination of unknown things(unknown to me lol) and kind of a fluke. But if it was a fluke i wouldnt have thought more than one would have done it? So any one out there have something like this happen to them? If so could you reproduce it? Im guessing not or i would have heard about it, since it would be all over the net but if you have any suggestions please let me know as i am still trying.

I got a couple gutbuster that are freaks. 4 inches tall with these skinny curly leaves, and crystals on it from about day 7. Should be interesting. The other I'm probably gonna kill.

I once had to hide my plants in the dark for a few days and unbuild my setup, years ago as i had people coming over to do renos. one of those plants i think ak47 finished real quick and was covered in trichomes and black hash like resin. finished in about 40 days but i kept it going longer. Unfortunately it would not clone at all where alll the other ones would easily.
I had fans for years after sharing that one around.
'That was years before i heard about the 36 hour dark cycle before flowering.

I have been trying to take some photos of them and im just terrible at it. Here are my best attempts:

Glad to hear others having some strange ones.
My photos i posted are : first one is OG 18, second is PF, third is Dark Spirit and last one is Bubble Gum. All are great but the first two were the freaks.
