Guys, having some plant issues and wanted to ask your advice. Yeah, I should probably post in other thread but wanted some local input .
About 5 weeks into veg I get what looks like a deficiency (maybe multiple). Large fan leaves get dark brown spots then start yellowing. New growth is solid green. I've only used FF Big Bloom once at quarter strength a couple weeks in (200 PPM). Plants were moved from party cups to 5 gal containers about 2-3 into growth and have been in current containers 4-5 weeks.
By looking at the pics and using the info below, can anyone tell me what the hell is going on? I did a GOOD flush with ph 6 R/O water tonight. Last gallon of flush had some Superthrive and CalMag. Many thanks all.
Ok, the info: This is an indoor, SCRoG, soil grow. I usually do waterfarm SCRoG, so the soil is fawkin with me.
