Looks like the start of a micronute def... leaves shown in detail pic are shoing a Mg def... flush that plant out completely and start feeding your bloom nute.
Personally I would also add a micro supplement to the first feeding. I've been using the micro part from the GH 3-part as a quick fix for that sor tof thing.
stinkyattic Reviewed by stinkyattic on . Any suggestions? I just went 12/12 3 days ago when I noticed some yellow patches on some of the lower fan leaves and the upper/newer leaves seem to be a little skinnier. They all also seem to curve down a bit. It's not getting worse but it's not getting better. (See pics) Should I change the nutrients? Any suggestions? Rating: 5
