maybe 30g on the small ones and 60-70 on the bigger ones? 150-200g dried/cured?
really depends on how they fill out. some buds are denser than others and can surprise you. when it ripens, imagine the buds shrunk to about half the size of what they are on the plant and can guess more accurately. Some of those colas might end up much fatter than we can tell from theses pictures.
Photoperiod plants can have more consistent outcomes and if you want can run them on same timeline, more or les. Though you may need more powerful lights for a 12 hour cycle vs autoflowers (18h -> 12h requires 150% of intensity over 12 to provide what was once given over 18, same cost in watts, though)
