Tanning of the leaves

[GrowerNew]

The tanning on the leaves seems normal when I look at similar diaries. I left it in the cold for a few nights to make the buds turn purple. But I'm not sure, do you think there is a problem?
I used 1.5ml/L BioBizz Cal-Mag this week.

6th week of bloom
9 pcs 30w CFL

Well looking closer not ready in my book what do the trichs look like?

[GrowerNew]

No mate, it is not ready at this stage, it needs two more weeks. My question is, is this color change in the leaves normal?

[9fingerleafs]

The leaves are showing deficiencies just like when you flush at the end of flowering, this could be because the cold prevented water and nutrients from being absorbed, water flow decreases when too cold. It was too early and buds werent developed

[GrowerNew]

yes I left it cold for a few nights to change color but now the temperature is fine. Do you think it will improve? will the buds swell more?

[9fingerleafs]

Yeah for sure they will. May take an extra week to bounce back, depending on the root size and health. And how hot the soil is. Be sure not to over feed now so they don’t lock out when they start drinking water again

[GrowerNew]

I don't know the temperature of the soil but the room is 23 degrees

[9fingerleafs]

That’s perfect. How cold was when you left them in the cold?

[GrowerNew]

13-15 degrees.

I give the nutrients at their normal value

[9fingerleafs]

That’s not that low. Not enough to cause those issues. Are you growing in soil or coco?

[GrowerNew]

Soil. BioBizz Light Mix

[9fingerleafs]

Then I guess someone who knows that soil and nutrients could chime in. I use coco and use hydro salts. I guess if the ph is in range it’s a matter of nutrient strength or health of the roots.

[GrowerNew]

Unfortunately, there is no pH meter, but it says pH 6.8 in the water I use. I don't know how true it is. I have used this water before and I was satisfied.
I am not satisfied with its growth at the moment, I hope the buds swell more in these two weeks remaining.

Thank you for your care

Those leaves are done. Cut them off so the plant doesn’t try wasting energy restoring them. They are only a hinderance to the plants health since they are covering bud sites and not functioning for photosynthesis.

Looking at all the white hairs, you have several weeks to go, and hopefully, the buds will fatten nicely.

Thank you very much for your comment. I did what you said and plucked the damaged leaves
