One of the plant leaves are turning dark purple (compare to the other plant with the same strain). This one is a bit different because I added molasses (molasses did make more crystal; will compare result next week jornal update) while the other is without molasses. Check pict

Judging by the temperature you're recording in your diary, it could be temp related even if it's the only one doing it. - Purple colour isn't really a bad thing, it's simply the plant switching out chlorophyll for anthocyanins, which lets the plant absorb a broader spectrum of light, tho less efficient.

If your growing straight in the ground likely just need a little extra bloom nutes.

Hi there! Most of the time purple colors are strain related and the results become visible when nights are atleast few degrees colder than the day and sometimes it needs to go as low as 18C to be fully visible. Purple color is also molybdenum deficiency but it is pretty rare unless you have way too much sulfur that locks it out. Either way the purple color is nothing to worry about but rather good thing 'cos it brings beatifull hue to your plant! Happy growing!

Could be a phosphorus defficiency, but why under fed or over fed creating lockout. Check your runoff ph and ec levels to see what you need to do. Cheers
