Hi all,
I have some yellowing on one of four plants. It started with discoloration on more then one, then i added some magnesium, but on this one it went further. I was reading about zinc deficiency, but i'm also watering with nutes that include micronutes(It looked similar to picture of zinc def. about a week or two ago). The problem seems to be only on tops closest to light. Its 400w hps in cool tube. I had it as close as 15cm or even closer at some times. But few days ago i moved it a bit higher. I didn't check ph runoff so far.. I was also wondering if it that is becouse of difference in temp at tops and roots. The room is at 22C
