pH fall

Thanx @m0use I hadn't thought about it, you're always on the spot 💪 Tomorrow i will start add SensiZym I'll probably have to use it from the start next time Thank you all buddies 🍀

Usually EC and PH change in opposite directions. So a PH drop would be a sign of over feeding. I do see some leaves that look burnt in your journal, but overall she looks happy and not overfed. But if both are dropping then that is usually a sign of something is growing in the water that should not be or its time for a water change. The only other thing I can think of would be if you were running CO2 as this can cause the PH to drop if your bubbling air from in the tent.

From my understanding the more the plants drink and eat the less water that will be available. This in turn increases the concentration of the nutrients in the remaining water and and it has a swing effect on the PH of the reservoir. If your in flower you could try increasing that PH to 6.2 so when it drops it wont be to to bad. The PH perfect products can work in a broad range but all the other additives will need it to be within your range. Good Luck!
