Brown Tips on some leaves - too much nutrients?

Today I recognized brown tips on a few of the leaves (see pictures). Is it something to worry about? I am having trouble identifying the problem and how to counter it. My best guess is I used a little bit too much fertilizer for this automatic? But I am unsure...

I also think it is a bit too much fertilizer. Everything else is looking fine though so I would not mess around with anything else in a panic. Your best bet would be to go about 25-50% less in your next feeding. This should straighten it out without skipping a feeding. My guess is this is happening due to too much salts (nutrients) being left in the soil when the media drys out. Remember you should ALWAYS water enough to have roughly 20% water run out the bottom. This will help rinse out the old salts left behind and avoids any nutrient build ups in your media. This is a common issue around week 5-7 because growers are not getting enough run off after every water. I think your plant will sort it out and bounce back. Good frost production so far as well! Hope this helps.

Also don't forget the CaMg in the biobizz feeding schedule. They will be needing it now in bloom. Sometimes they can go without.

I feel your self assessment is accurate and the tip burn means they getting just a bit to much, This is a sign to back off the feeds a bit or it will get worse. Don't need to pannic and flush or anything just give it time to use it up and make a note it wants less then that you give it. I find it easy to monitor my feedings solution with a TDS pen, then I just dilute down the feeding solution to whatever EC/PPM value I desire. EC is better vs PPM as it can be all over the place depending on the model of pen and where its manufactured for. eg. 500ppm=1EC or sometimes is 700ppm=1EC but 1EC=1EC in almost every scenario. Good Luck!
