If "the other three" is close to their next molt, they would not feed that frequent and most likely will stop feeding completely one to two weeks prior to a molt.

You can put it that way. Each time after a scorpion has just molted, do not worry that it will starve if it does not eat immediately. On average, they should start feeding once their exp-skeleton has fully hardened about 7-14 days after their recent molt.

When dealing with scorpions which might be approaching a molt or has just recently molted, it'll always be good to offer head-crushed feeders unless you are there at all the feeding session and religiously remove uneaten feeders immediately and not leave them overnight in the same enclosure as your scorpions.
