Hey
@HPS Only sorry it took me so long rough morning.
Ok get you room temps under control 20 c to 26 c is what I keep to.
And rh yeiks get it up to 50 at least.
And tidy up under the canopy and get some air flowing through there.
But that's not your major issue.
Big Bud is a flowering booster no nutrients.
Bud Candy helps root zone with sugars no nutrients.
Rhino Skin is silicate for cell wall strengthening no nutrients.
Your soil is depleted and they are starting to starve.
If your happy with AN. get their trio micro grow and bloom.
Start feeding full strength according to the schedule for what week your on.
At
6.3 ph
Letting dry completely in between.
Are you alternating feed/ water?
Stay safe
Bill
