High guys
I'm 30 days into flowering and my the leafes of my criticals start to turn yellow although I did not change a thing to what I do usually
Can you help me identify my problem?

Ghe Fertilizer Grow micro bloom (1-1-2)
Total Ec 1.6 starting from RO Water with CalMg to 0.5

They stand in Hydroclay and get watered every 20 Min.

Please Help me!

Looks like you know what you are doing. I am NOT familiar to hydro-clay. To my eye it looks like magnesium. I would suggest CM to 0,3 than epsom salt till 0,5 and rest. Keep EC where it is. my noobish advice, maybe some hydro Geeez can provide more useful advice…
