Auto DieselRyder & Williams Wonder (60 Day) 7 weeks with lots of PICS

First grow with any strain that wasn't bag seed. Had the grow all figured out as far as scheduling various strains Laughing Buddha, Jackie White and 2 Auto flowering DieselRyder & 60 Day Wonder (Williams Wonder). I ran out of room in veg room very quickly or rather ran out of light 1-4' T5 and 1-250W MH. I already had the Autos under HPS 20/4, so I moved some of the Sativas to veg under the HPS. Before long I had 9-3' sativas still vegging. I couldn't wait any longer so I shut the lights down 12/12 before I had plants growing into the house. I started moving the autos into the flower room when lights came on & moved them under T5's after the 12 hour HPS cycle for the last 8 hrs a day. The LB's have a 100-120 day flowering period & have had to train them a tad.
When the grow started 7 weeks ago my seedlings fell from a shelf and out of thier cups and had to guess at which strain was which. I think I did good guessing except for what I think was a mix up with 60 Day Wonder (freebie) and the Diesel. The plants are all 7 weeks old tonight. Not sure what the flowering perods are, but it looks like the Diesel might beat the 60 day? Crystals are just forming (saw it in the pictures before I saw it with naked eye) on the Diesel and hairs are turning. 60 Day is still totally white, buds still filling in and no sign of crystal formation yet, but still very tall.
Leaf tips on Diesel are a little burnt. Started when I went to full FF nutes and espciall after started FF Cha Ching. Don't know when to stop feeding Diesels and start flushing?

Nice job strains sound yummy + rep I would let them go a little longer

Really curious how the autos smoke. If it is as good as it looks, I have time for another "batch" before the Buddha is ready. I figure I have 2-4 weeks left maybe?
