Help me confirm this Calcium deficiency diagnosis?
val95started grow question 3 years ago
I'm not quite confident in my ability to diagnose this using the charts you find online. Can someone confirm this auto in DWC (pH=5.68) needs some more Ca?

Looks like it to me, but I also see some leave affected by pH going out of range. Try bringing the pH up to 6 and see if that stops the Browning. If your pH gradually goes up then start at 5.8 and correct it back when it reaches 6.2. if your pH gradually lowers start at 6.2 and correct at 5.8. This will ensure your plant hits all pH ranges to absorb everything.

PH Fluctuation Early Signs?I am worried that I either have early signs of PH fluctuations outside of 6.0-7.0 range or early signs of a calcium deficiency.
As you can hopefully see in the picture the tips of the first set of true leave seem to have little spots of discolouration.
Any help is appreciated😊3 years ago
