Hey man, checked out your grow and just wanted to drop a few notes:
Your pH is too low for your medium. If you’re using organic nutrients, try to water with a pH around 6.2–6.5 — the microbes will handle the rest.
You really gotta dial in your watering technique — that part’s super important.
You’re using BioBizz LightMix, which always needs some added nutrients. Not sure which ones you’re using, but definitely supplement.
Right now, that low pH is locking out or limiting things like phosphorus, calcium, and magnesium — and you can already see it in the plant.
Hope that helps! Keep it growing 🌱✌️
