First grow

I would switch to distilled water if possible. Its so hard to say by looking at pictures. Hope this helps. https://www.growweedeasy.com/cannabis-symptoms-pictures

Hey there Tiny Couch, you're absolutely right that they're ready to be flipped, that much you can tell by the new growth happening . Still though with a topping which is a HST , i would say try to aim for an average veg of 7 to 8 weeks. Topping can really reduce your yield, that's what folks dont realise. 5 weeks is very short for veg, but because of watching folks do it online it got kind of normalised lol The difference in yield for a short veg of up to 5 weeks and an average veg of up to 7 weeks is really quite huge, and in my personal opinion it's totally worth it if you have few plants. Go for 8 weeks even, that's not even a long veg, not really. Hope this helps ! 🚀
