Week 6 here,pictures above, 7/21. A few plants sho...

It may be lockout also... grab yourself some calmag, When in doubt I always add some calmag to my feeding/watering. keep us updated! ______________________________ Do Not Hate. Educate and Cultivate!

Hi. I’m hydro not soilless but I’d say she has a bit to much N. Try 8ml/g base. I’m hydro and use 5-6ml/g pH Perfect Sensi.

Def Nute burn. I have found that: flushing, then one watering, then return to nutrient schedule does the trick.

I noticed that you changed your nutes this week. They contain a lot more mag than the veg nutes that you were using. If you look at the nutes themselves, you are giving them everything they need to thrive. I wouldn't add any more nutrients to your current feeding schedule for a bit. Give the plants time to adjust. In the meantime, did you do any flushing in between ending veg nutes and beginning flowering nutes? Flushing does wonders, especially if there is a nutrient uptake issue. Have you taken any readings of your runoff? Overall, they look pretty healthy, but you need a little more data. The numbers you give are spot on, so that means there is something else.

Hello ! My idea is you have a potasium def... Add some pk and should be ok..

Wat u have is a cal mag problem this is from your ph being off your plant is sucking it out your bad leaves to keep your other ones green see how your leaves are turning yellow you need to put your ph at 6.1 to 6.8 to get the mag back in your plant fast add calmag 4 ml a gallon and cut off the burnt leaves asap✌️✌️👍👍

It looks like nutrient burn to me. I’d suggest trying to decrease the nutrient levels. Maybe try 1/2 - 3/4 strength. Good luck 👍

Hi @Pete7776! Looks like a potassium deficiency to me, since only older leaves are affected, with brown/burnt edges. In this scenario I would double-check that the pH-pen is correctly calibrated, and increase K in her next meals. Keep us up-to-date and happy growing 👊
