White Widow Auto - Royal Queen Seeds

Hello my friend, this plant is looking great! Don't worry about the purple leaves. This is not a deficiency. And can be caused by cold weather or genetics.

This looks like the plant's natural change from chlorophyll to anthocyanin in its leaves. My lung room gets to 59°F (15°C) during lights off, and my current grow started to turn "grey/purple," much like yours is looking like it's doing. If you want an example to ease your mind, check out my Nutter Butter diary (you don't have to like it or anything, just trying help) to see the grey/purple. If you look at their early weeks of flower you can see similar colors developing. Only thing I would say I did wrong is too low of humidity throughout, chance the purple tips for me during veg. Keep watching it, but I say nothing to worry about currently.

Es sieht danach aus als wenn es kurz mal etwas kälter war als die Nächte davor. Das lila macht der Pflanze nichts negatives. Auser Man mag die Farbe nicht:) So sieht sie sehr vital und rundum glücklich aus. Sehr gute Arbeit 👌🏻
