Leaf Burns

Hey Chico_Grower! First of all your plant has a good green color so it looks healthy 👏👏 taking out the burnt tips. These burnt tips look like nutriente burn. A) too much nutrientes in feed. B) soil isn't draining properly and nutrientes are building up stuck in soil. Theres really nothing to do but stop it before it keeps burning. 😪 Biobuzz have really good substrate so its easy to over do it with nutrientes, I've had it happen a couple times. 😢 What you can do: Feed only water for the next couple of days, if you have Enzymes you can use the minimum. I used it and really helped to clean the roots, after a week my girl were back to full life. Don't forget that the plants don't show results from treating roots until 3 days later or so.. Good luck grower!! 💪

Those leaf tip are burnt much farther in than typical nute burn and accompanied by burnt leaf edges making it look like a potassium deficiency to me. Plant doesn't seem to be showing signs of heat stress which can affect the leaves similarly but is usually secluded to the leaves closest to the light source. Most common reason for potassium def is a nutrient or PH issue. Potassium is best absorbed by cannabis grown in soil at a ph of 6.0-7.0. as long as enough is present. This deficiency can be made much worse by overwatering. Just make sure your lights aren't too close to rule out that possibility, ensure you give a well balanced nutrient with increased PK for flowering stage and adjust your ph to the correct range. Hope this helps. Cheers
