High rh and temp for autos

I was using this method I learned which is to keep rH throughout plant life until 2 weeks before harvest around 80% for rapid growth and Temps between 22-25 Celsius
I think this advice I had was directed to growing photoperiods not autos as I did not achieve perfect results looking at the plants height which should be based on these 2 strains I'm growing is 100cm I achieved heights between 50-65cm.

I'm in week 7 and if I followed the suggested method I should now park rH as low as I can and leave temps as they are at around 25c


Is what I'm doing correct as I don't see buds forming although I'm starting week 8 in 3 days and planning to harvest by the end of week 10

My next move will be to park rH at 45% and leave temp at 24-28 Celsius, agree?

80% is pretty high for even veg.
To have proper VPD you would need your temps in the low 30c
I’m not 100% but I’m sure you would need to run Co2 to be running up in those ranges.

Your plants don’t look like autos. I can’t even see pistols in the pictures. Every auto I have grown has been heavily flowering by week 4-5.

Your hope of harvesting at week 10 is long gone. I would flip your lights 12/12. And you will have 8-10 weeks from then. My guess is they are photo plants.

Your plants are not autos, flip your light cycle to 12/12 and wait 10 more weeks.
Regarding RH and temps level. 80% RH is suitable for a seedling. In veg end early flower you should keep around 60% RH. Later in flower you would like to have 40% RH. Keep temps 22-26 in veg period and 22-28 in flower if you can.
