Tropicanna Banana - Super Crop&Long veg.

Hi there! I'd say keep 'em. They are filling the right side of the tent nicely and the tops are looking good in those. If you cut them you need to train your plant more to fill the whole tent if you want to max out your yield and used space

Hey Growmie, Actually neither of these will cause red/purple stems, but a Magnesium deficiency can cause purple stems. A good cannabis-friendly nutrient system has a significant amount of magnesium, but if you’re using very soft water, or RO water, you may need to add a Cal-Mag to your nutrient regimen. Also, Temperature can play a part in this too this – Heat or especially cold can trigger red stems in some places. Big temperature fluctuations can also do it even if the temperature is in a good range. Hopefully, I answered your question and remember Happy Growing and Free your mind one puff at a time.
