Thanks for the inputLooks like you got yourself a purple strain going on there.
Got some yellowing happening too so maybe a little more N and some Epsom salts to fix any magnesium issues. The extra sulfur from the epsom helps to get more resin too.
I'm pretty sure those plants are wired to go purple in flower. Cool nighttime temps can bring it on stronger too.

What are you growing in?Thanks for the inputI have 2 plants of the same strain in that box, they both get same nutes. And the other is green without any signs of purpleing.
Forgot to mention - I accidentally put too much epsom salts when they had a really bad magnesium deficiency... Actually, when I think more about it, all of my problems started after too much Mg. I flushed everything twice but problems still occurs: calcium deficiency (or lockout) is the worst one happening right now. Also I was getting dark spots (phosphorus deficiency) so I increased bloom nutes, and then purpleing started to happen. Lots of yellowing at the bottom leaves. pH were always in a good range. My plants were doing great until Mg incident, and now blooming is slow ...
Do you guys have any suggestions how should I complete this grow? Increase/decrease nutes, give more/less calmag? About 3 weeks left until harvest.
Btw, OldMedUser, thanks for advice. I should definitely increase N because I only gave them ~0.5ml/l of Biobizz grow couple past watterings.
ThanksWhat are you growing in?
Your 3 weeks away from finish and your plants are just showing their true colors, there is no problem.
Adding N this late won't really help, and your plants don't need it now.
Next grow I would only use Calmag (once a month) and forget the salts, seeing as Calmag adds what you need plus N.
I would water only now or lite nutes if in soil until finish, but in hydro bring your nutes down to 1400 ppm.
Plants look good.
Nice job![]()
Temps in 68-79F range (20-26C).temps?
ThanksI'm growing in Biobizz lighmix.
It's possible that my both TDS meters are broken, but I have never fed them more than 700PPM and that's including water at 200PPM + 3.5ml/l biobizz bloom + 1ml/l biobizz grow + 2ml/l CalMag + ph down + some amino, fulvic and humic acids...
Does anyone also uses Biobizz products and could tell me if PPM should be higher?
I made an experiment yesterday and put 4ml/l (full blooming portion) in 200PPM water and PPM raised only up to 350-400... To get to 1400PPM I should probably put 8-10 times the recommended ammount

That's perfect in soil, good job.It's possible that my both TDS meters are broken, but I have never fed them more than 700PPM and that's including water at 200PPM + 3.5ml/l biobizz bloom + 1ml/l biobizz grow + 2ml/l CalMag + ph down + some amino, fulvic and humic acids...
In soil I wouldn't recommend feeding a plant at 1400, more like1000 max, and then only once a week, assuming you water 3 times a week.I made an experiment yesterday and put 4ml/l (full blooming portion) in 200PPM water and PPM raised only up to 350-400...

From my experience purple leaves like that are not a sign of a purple strain. I've grown many purple strains. Most had green leaves and purple flowers. Some do have purple in the leaves but not like the ones the OP posted a picture of.
This is a purple strain of mine. Purple flowers and green leaves.

This is a PCK showing purple in the leaves naturally not from a plant issue.

That plant looks like it's suffering from nutrient issues. Probably too much bloom nutes.
But what do I know.![]()
