So I asked Mr. Beans to check pH and he ended up realizing that hydroguard is labeled as mL/gal and EVERYTHING else was mL/liter so basically I have been underestimating everything by a 1/7th 🤧 (and I call myself a scientist pfft). His reservoir was fully cleaned and I tried to give a more appropriate amount of nutrients without overloading him so I hope to see some growth within the next week :)
Update: Hes growing!!! And he smells minty!!
