When you water try to keep the leaves dry. The lights will burn the leaves with droplet son me like mini magnifying glasses.
I don't know if what you are seeing is that but I can agree you need to calibrate your PH pens once a month in a active grow, to much happening to not do it.
also if your using liquid nutrients like biobizz or general hydroponics your PH needs to be between 5.5-6.2 for soiless. 6,4 is to high.
If you not monitoring your EC yet, i suggest you do as well for liquid feeding. the feeding guides for most bottles are to high and you can get away with 1/2 the recommended dose.
Best of Luck and Happy Growing!

One of the thing could be water droplets on the leaves and light will make burn spots trough droplets, or your ph is going off ,on some photo I checked your leaves are claving of too much nitro ,you overfeed with N.

Even the most professional pens will need to be calibrated. My pen is always spot on when calibrating. But this last time it went out of calibration between calibrations. First time in 2 years.

Looks like the start of a PH imbalance. Make sure your pen is calibrated.

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency?
This is mostly on one spot near darkest edge when tent closed. Thanks!9 months ago

Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?10 months ago

Defoliation late in flower on Auto'sI like to defoilate, If I were to pick majority of the fan leaves off of these plants being Auto's, will they react or stress too much? I like to defoil near the end of flower to really push all the focus to the budsites. Happy Growing!a year ago
