At 50% humidity and 78 degrees, you are at the high end of VPD. Anything over 78 and you are in the red…VPD wise. You could either lower your temp or raise humidity. If you raise humidity be sure you have a fan moving the plants around a little. I would lower your temps and take the pressure off the plants.78-85 degrees 50% rh. I’m upstairs and it gets warm. Feeding GH trio and pk booster cal mag and microbes. Tried advanced nutes, dr earth organic as well. I’ve gotten harvests outside no problems, and indoor autos. It’s just the photos that go south in week 3-4 of flower.
Yeah I’ve been looking at vpd and noticed that it was high causing the plant to transpire too much causing them to uptake more nutes . I may have to get a portable ac.

vpd is not causing the issues.Yeah I’ve been looking at vpd and noticed that it was high causing the plant to transpire too much causing them to uptake more nutes . I may have to get a portable ac. Thanks
Before you do a flush do a slurry test and post the results that way if your results are good you may not want to flushvpd is not causing the issues.
You could be right. My point is if you get the VPD right, you can eliminate it as a possibility.vpd is not causing the issues.
Mars hydro tap 2000 @mostly 60%. 20 inches above the canopyI'm gonna throw this out, what kind of light and how high above the plants is it? It really look like there's some light bleaching going on, may not be the only issue, but it's a contibuter.
It would seem fundamentals have, for the most part gone out of style.Let me preface this post by saying this is LITERALLY my very first post on this site. I'm sure I'm a n00b compared to other guys, but I am consistent in my methods and for the most part successful.
Have you ever tried a plain old traditional grow? What I'm getting at is that I think maybe you should try your hand at developing some fundamental/basic cannabis grows to make sure you get that right, and then try with the more complicated stuff.
I've had a couple times where I saw those symptoms, but they never got very far. My suspicions are something in your growing medium. Try regular old fashioned FoxFarm and regular tap water. Sometimes less is more, I guess?.
It seems like it, looking at these forums. You know my first grow went almost perfect and that was actually bad. I think I got too cocky and ended up getting sloppy then realizing I wasn't as good as I thought I was, hehe. I had to screw up a little bit without relying on luck and get a consistent pattern going (which I have at this point). But, I only do very basic stuff. Plain FoxFarm soil. Tap water (too lazy too mess with PH stuff). Some pretty cheap lights.It would seem fundamentals have, for the most part gone out of style.

That is the reason I'm here. To learn the fundamentals from more experienced growers who want to help those who express the will to learn.

Did you make it yourself or did you buy it? If so, what brand?I recently up potted and cut a bunch of the crispy and deficient leaves off to see if the plant would respond. Been hesitant to flush the soil since it’s a living soil.
Top of plants.where's located your temperature probe in the tent ? near plant tops ? if not check the temperature there
look a little like manganese toxicity that could be triggered with heat stress. but not sure
Normally use happy frog, this time i tried a local company out of richmond VA. Big worm organics https://www.instagram.com/therealbigwormorganics/Did you make it yourself or did you buy it? If so, what brand?
