Buds not bulking up

Hi guys,

Need a bit of help with this one.

Grow Details:
Coco coir grow
SBG seed from seedsman
600w HPS
GH flora trio nutrients


My girl is 45 days into flower with an estimated 15-20 left but she hasn't started putting on weight.

I've been watering with 5.8 - 6.05 pH water and 1100-1300ppm water (nutes included)

I bumped the ppm to about 1300ppm during week 4 of flower but some leaves started to get spotting so I gradually decreased it back to about 900 over the last 2 weeks. (Tap water here is 10ppm straight out the tap)

I flushed her over the weekend because I figured it may have just been lock out and didn't water until she was dry about an inch deep (1.5 days). She's being watered with 900ppm atm.

I'm still getting weird colouring on the leaves and the buds aren't bulking up yet.

My temps have also been a steady 24-25° during the day and 18-21° at night.

The only thing I've considered it may be is that my light is either too close or too far from the tops?

It's been ranging between 45cm-60cm all grow because some sites seem to get light burn when it's closer to 45cm.

Any advice or idea on what may have happened or is it too late to save?

Looks fine to me

You have more than 15-20 days left.
Most weight comes at the end.
Looks good!

For reference, this plant has around 15 days to go, and it is on day 78 from flip today. You got a ways to go, so I think you’ll just have to wait it out.

Thanks for that! What strains are you growing?
And to be honest it's been 46 days from flip* not flower should I be counting from the day she first showed buds?

Run off ppm?

Mine is GDP. I always count from the 12/12 flip, but it appears there’s various opinions on that.
