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.

yellow leaf tips"I've noticed yellow leaf tips on one of my plants. My watering pH was 6.5, and EC was 1.6. Today,
I flushed it with osmosis water (pH 6.5), and the drainage water had a pH of 6.2 and EC of 1.0.
Is the problem resolved now, or do you have any other suggestions?

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?

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!3 months ago

Yellow leaf tips in flowerShe's pretty far into flower, in DWC, and the environment and nutrient schedule have stayed consistent for a while now. I'm using GH Flora Trio at 5ml of Micro, 2.5ml of Gro, and 7.5ml of Bloom per gallon.
The leaf tips are looking burnt, should I ease off on nutrients or what?
