How would I go about correcting a manganese deficiency? I’ve never dealt with this before. The 3 plants I have are taking a very long time in flower. I’m on 10 weeks with crystal clear trichomes still. A few brown hairs here and there. Plants are about a foot tall after allowing to veg for 12 weeks as they did not grow quickly.

[/quote] I don’t understand, you claim climate control but no supplemental CO2?
You’re saying they also grew slow? I see an O enrichment if it’s a “controlled environment”, and you’re saying you use carbon filter, is that on a Re-circulation or vented externally placing negative pressure on the room? Either way, you’re only a CO2 stone’s throw away from having a true laboratory environment. H202 is another necessary ingredient to keep dissolved O levels higher in the aqueous nutrient solution (hydroponic), tests are performed on both to gauge any particular lab’s consumption and exchange (high CO2 means high CO2 in the medium also, from natural exchange. A touch here, and tweak there, and your expenditures for environment control (AC) would bring home the bacon!
Those little spots should be the least of your concerns with climate control and no CO2! (mainly)
Otherwise they look like they were splashed with something that spotted them more than a sudden surprise nutrient deficiency that sprang up out of nowhere on a system that’s been running and proven.
Somewhat of a beginner here. This is my grow. This all came about in like a weeks time. I am considering a hydro setup but currently am finishing up the soil grow. Not sure where to start with hydro tbh. Trichomes are just starting to get cloudy so I don’t have a whole lot of time left and I don’t want to waste it at this point. As for the climate control… I just have this commercial hvac unit for the entire building each room is individually controlled. that’s temperature and humidity controlled. I don’t have a way to get a Pic in natural light but I took pics in the back room with ambien tlighting and flash on low. It won tlet me add pictures to this for some reason. I added cal mag 4ml to a gallon and watered yesterday it actually made the one worse. Almost like a bad nute burn Can’t say it changed anything with the spotted leaves on my other plant
I would flush until your ppm read 900-1000 and your pH is on point 6.5ish I add one teaspoon per gallon of CalMag but it really depends on what water source your using
I had this problem also early on. Nute burn, nitro to and lockout. I watered with just pH water for 4 weeks. 2-3 gallons per plant each watering. After TDs cleared I used 1/4 dose calmag every feed for 2 weeks and black strap molasses 1 tablespoon per gallon. All is good and they grew 2 -3 feet in a few weeks.
