This is a sign of phosphorus deficiency! It might be due to incorrect substrate pH. Or maybe you're overfeeding it with nitrogen and forgot to add phosphorus! If you're growing in soil and not using any fertilizers yet, it's likely that the soil contained little phosphorus and needs a Bloom supplement added to your watering! If you're already using fertilizers, then reduce the Grow supplement and increase the Bloom supplement! 👆 The ratio for the middle and end of the vegetative stage is 1:1 Grow:Bloom 👆 Good luck, bro! ✊😇

First time growing/Need help in late flower Over the last 9 days my plant has gone from happy and healthy to sugar leaves pointing straight up near the top of plant and drying and curling up on the lower levels. Is this from too much light or did I over feed late in flower? First grow/ no diary. Can I save or do I chop?

Browning on the leaves?I am worried about the leaf colour I feel like it’s slightly browned on the tips. Interested on what others that know what they’re looking at more than me think. Good chance I’m being over protective. I appreciate you.

Is 8 oz of water about right for 3 weeks old plants? Also thinking about LST, is it a good time to start that now? Also is buying nutrients worth it when it comes to harvest? Or is it more dependents on the power of the light ? Thank you for any advice 💯🙏🏼
