Deficiency?
iamdagrowastarted grow question 4h ago
Its the first week of flower and some leaves are starting to act up. I am thinking phosphorous maybe? pH is between 6 and 6.1 in biobizz light mix, EC is at about 1300 µS. I added CalMag from the very start. Would appreciate a trained eye!

Hi mate the ph is aboit low for soil you want between 6.2 and 6.7.. Magnesium overload and caused calcium lockout as there both positively charged cations there competing..
Low pH.. Calcium def and possible manganese def aswell.. Good luck growmie...

Looks like early stage magnesium or light nitrogen deficiency, not phosphorus. Since you’re in Biobizz Light Mix and already using CalMag, try increasing overall feed slightly or add a touch more Grow for a week. Keep pH steady around 6.2 and watch the new growth if it stays green, you’re back on track
