LED Auto Critical Purple

Looks good! My Critical Purple ripened at 10 weeks. It was like watching your kid go off to college, bittersweet.

The leaf color change could be a variety of things... Nutrient deficiency, PH issues, etc. But I don't think its heat related specifically. In fact in your case I think its just a sign you are getting close to harvest. It is not uncommon for leaves to change color and fall when getting close to harvest. Just like the trees outdoors that change colors and drop leaves in the Autumn. Here I think its a good sign. I'd recommend you keep on doing what you're doing. She looks great so far! 👍

Hi @MrWeebles! This looks like a nutrients-burn to me. I see you're having burnt tips and edges on older/bigger leaves, those tiny leaves are just having a different reaction to the toxicity. In this scenario I would give it a good flush with only pH adjusted water (6.0~6.2) for at least a week, otherwise this might have a negative effect on the final product's quality. Keep us up-to-date and happy growing. 👊

Alright so I just switched the timer to 18/6. I hope it doesn't mess up the cycle since I haven't had a real successful grow yet.
