I’m running 4 sf2000 and 1 sf4000 in a 4x8 tent. Set at ~20-24” from the canopy. Temps are good 74ish lights on and 64ish lights off. I’m in ffof and happy frog soil. I always adjust Tap water ph to 6.3-6.5. Been adding ffof trio bites since a week or so into flowering when I started to notice leaf color changes.
I've had this issue myself more then I care to admit and it's super frustrating. Same deal, great veg and stretch then boom mid-flower 3-5 weeks in it hits.
The timeline leads me to believe in my case that it's salt buildup from poor watering practices. Do you know the ppm of your runoff and of your tap water? In my case I wasn't watering to runoff/ was allowing pots to sit in runoff. I was using organic dry amendments, but my tap water comes out @300-400 ppm and I suspect it was these dissolved solids (carbonates) that built up and caused my issues and why I asked about your tap water.
I really hope you can figure this out and i'm really interested in others insight into the issue. A couple other problems I suspected were lights too close and overwatering. Hope this helps a bit and good luck!
MiMed, you might have a point. He has like 1200 watts in a 4 x 8, alot but not too much IMO. Now you have me thinking the plants might be underfed. I went back and looked at the pictures and the plants look to be eating the nurtients out of the fan leaves close to the buds. I have seen this in late flower but not to the extent in the pictures. It would be helpful to know the PPM's thru the grow.Sounds like a lot of light for a 4x8. Just that makes things more challenging.
But if the environment, nutrients, watering, etc. is on point then i would look to root aphids. I have similar symptoms in my garden caused by them.
