im having simular issues...aprx two weeks into flowr. problem is i have two strains, one that loves the nutes and one that hates em...still dialing that in...but that is the root of my yellowing issue...over/under fertalizer. as yr plant grows its need for nutrients and water change, sometimes finding the right feeding schedule can prove to be a bitch...thats just my issue...good luck to you.

shit, i didnt look at the pics up close until after i posted this above...do you spray your plants with water at any time while they are under the lights? i made the mistake of doing that, and got very simular burns to your pics. also, if your watering with nutes, be careful not to let any of that water touch the leaves....in my case, i have burnt leaves that way too...but that spotting, looks so much like what i had due to spraying water on leafs.

yes! i used cal/mag as a foliar spray, i waited to turn on the lights until the leaves were dry. I guess ill wait longer...

yeah, i would say maybe dial back that cal/mag to a level your plant likes...plants are all so different, so even if the label says a certain amount, i always start low, and work up. but you can clearly see your plant is hating what its getting right now. why cant you put it in its soil? or in its water... whatever the situation

TY, the ppm is around ~800. After your advise I think i will set up a separate hydro for each plant and tinker with what each plant likes best. Any advice for first time with autoflowers?

well, what is your questions with autoflowr? i have done alot of studying on them, because i am about to throw a couple auto bubblicious seeds in the dirt that i bought from nirvana. i have no first hand knowledge like i do with regular strains, but like i said, i have done alot of research, and feel i am ready to take em on. what kind of auto seeds did you get?
