Hey Now all community members!
Been a big fan of the site for some time, but I’m a new member because I’ve got strange new issues going on in my indoor tents. I could use some troubleshooting by those who have had the same results. I’m trying out a different soil than I usually use and have a nute lockout(?) happening, I believe… (?) Or, what say you guys??
Soil: Pro Mix BX General Purpose with Mycorrhizae in 3 gal cans.
Nutrients: Earth Dust dry organic blend; initial mix-in and top dressing.
Light: Crecer PanthrX 640wt. LED on 18/6 photoperiod.
Water: 8.5 well water, pH’d down to 7.0
Soil pH holding at 6.7 on average between 12 pots.
Average tent temp. 79 degrees with average tent humidity at 47 percent.
Plants are 34 days since transplant.
They started to “turn” on larger leaves; mid-plant at around 18 days. Plants were top dressed with more Earth Dust as directed. Showing interveinal brown patches and brown spotting. Marginal tips also showing signs but not really on leaf tips. Eventually curling, yellowing. This was not an issue with previous soil trials, with everything else being the same. Issue is not really affecting the newer growth and shoots. It seems to appear on the older and maturing fan leaves. Thanks all!
