Hey guys. Been seeing unfamiliar sights in my current grow as well as with the last round in the same room. Foliage has what looks like blistering, foliage being eaten away at. Some leaves have even developed holes through where the blistering starts. Some very light, light green new growth, with tiny twisting and yellowing at leaf ends. Also have the same strain growing in two other rooms showing none of the same symptoms, but grown with different nutes. Here are the details...

- growing clones of SFVog x GDP, been running this strain for bout 1.5 years
- plants are 1 week into flowering after 6ish week veg
- 24" tall
- 2 gal fabric w/ 100% coco DTW watering 3x daily w/ bout 20% runoff
- Veg Bloom nutes, currently getting fed 1.6EC 6.0pH 70F, tap comes out .2EC
- EC and pH remain stable, I usually mix 4-5 days worth (was just told by VB to just circulate and not aerate reservoir, which I had been doing, changed that about 10 days ago)
- Was using VB "push" (CaMg) as a foliar once every 3-5 days
- Room has 8 Dimlux DE 1000W, currently running at 650, with the 2 week veg time in there being run with every other light (4 at once) at 600
- plants are 30"-40" from lights
- room is 22Lx10Wx8H (1760 C feet)
- AC is still getting dialed, but most of lights on cycle is 78-80F w/ 55-65%, lights off has a dip in temps right now to about 60F :( but humidity remains 55-65%
- Have had a thrip issue that I have been treating with Spinosad foliars that looks pretty handled, the look of some of the growth screams russets to me, but I have scoped all over the place and can't find any
- growing for bout 10 years, soil for most of it, coco for the last 2 years

New to me, really appreciate anyones input, I'm stumped
Thanks FarmFam!
