I had one other think it was zinc as well. And with "rusting" blotches that seems to be the case. My ph has been on brink of its high limits but the peat so far has reduced the ph. I flushed today to clear out any nutrient lock, ph imbalance, etc.. The ph of the water (which was distilled 6.0ph) didn't fluctuate anymore than 6.1-5.8ph. Little weird huh? I guess peat in its forms are all different. I wish though I had bought a mix, potting soil.

Anyways I'm going to look up the information on zinc deficiency. If I can treat it at same time of flushing I'm all for it. I put a very light fert mix (10% of reg) to try and get nutrients back to the plant. Maybee that'll add some zinc since it says on bottle it provides some (general organic - grow)
mgjscdhl Reviewed by mgjscdhl on . Yellow leaves, spots - First grow - White Russian - CFL I did some googling prior to this, but honestly I can't nail it down. I beleive the issue started after last feeding (4 days ago). This White Russian is a clone I gotten a month prior. Its transplanted into soil 16 days ago. While it went well it took a few days for yellowing to disappear. About 3 days ago it showed up again. At first it started in middle (I think) and only effected the lower and middle leaves. One is yellow, probably canary yellow, and some dark almost red spoting on edges Rating: 5
