Timing can really get you with harvest, I feel for you and have been in the same situation.
Here is some good news, some people leave there plants without water a few days before harvest, they say the stress increases potency. They turn the lights off and let the plant start to die. I'm not sure I'd leave the plants in darkness for 6 days, but if you can figure out a way to schedule your lights off for the last 3 days, this may work for you. Basically you'd be allowing the plant to live with water for a few more days and then go without water and light for the last 3 days....
Day 62 for early flowering strains sounds just about right, and that final week may make all the difference.... What strain is it and what is the estimated flower time? Are you seeing clear or cloudy trics (on the buds) now? Have the pistols turned brown curling in, or are they still white?
One way or another I think another week or two will really help potency and final bud weight.... Harvesting early with clear trics is a real shame !
Late note: I looked at the pics you provided (nice pics by the way)) it looks like your real close with cloudy trichomes. I'd still try to stretch it out another week if you can, but harvesting now won't be a total loss.. One the other end, if you just water and leave the plants alone for 6 days, they might die, but your getting ready to chop now anyway, so its a win/win.... Who knows, they might make it through 6 days without you.
