hi there Habosabin, that's micronutrient deficiency, you're adding silica which is basically optional but you're forgetting calmag which is absolutely necessary in soiless grows. Just add calmag asap . Hope this helps ! 🚀

Is this an expected fade and if not, how do I fix these leaf issues?I'm growing a NightOwl auto in DWC and it's on D58 (suggested flowering time is 75-85 days). The plant is looking like it's fading (getting cal-mag and different types of deficiencies), but I think it's a bit early for that based on looks. pH is 6.06, 840 ppm, 68F water temp.

Does the paleness concern you?Plant #1 seems a bit more on the pale green/yellowing side of the spectrum. Especially compared to plant #2. I have been feeding this week on a gradually increasing schedule. Not enough characters to go into it here.

A bunch of different leaf symptoms appeared over just a few hours, can you spot the issue in my detailed diaries and solve the mystery?Everything was well, until over just a few hours they developed all kinds of symptoms. I have 2 diaries here for the grow, the 2 called “Grow #2” and I am very detailed about what has been done day to day. So please have a look and see if you know what might be happening
