This plant has been in flower for about 4-5ish weeks now. leaves are turning yellow and red with burnt tips. tested runoff pH at 6.8 today when I watered so I don't think its pH issues. been feeding a good bit of bloom nutes so ik its not P deficiency. Anything else?

Hey! This looks A LOT like Molybdenum Deficiency.. same color and spot patterns on leaves.. What throws me off though is this deficiency normally shows up with low PH levels.. and your's is at 6.8 I'm not sure. My initial suggestion would be washing the roots with PHed water, then water with nutrients that incluid Molybdenum. To be honest taking the PH down to 6.5.. would be my suggestion if this didn't look so much like Molybdenum Deficiency but with your PH you shouldn't even have this deficiency.. Hope this helped. Good luck and happy growing!

Hey there FTLS, I've gotta disagree with everyone here for once. It's clearly K lockout, this you can tell from the K deficiency symptoms even though you're adding it. The colorful discoloration is the dead giveaway. You know it's not Molybdenum because it's never that one lol also you're adding plenty of specialised minerals and i'm pretty sure they'll have that in there in some form or another. It's not pH because of the more "even" yellowing, the yellowing would be more patchy and unpredictable if it was pH fluctuations. So it's K lockout, probably because there are several NPK nutrients each with their own K you're adding to the feed. The bad news is it's gonna get worse before it gets better , try removing NPK from the feed as much as possible and hope the plant bounces back on it's own time probably two weeks. You can also flush by watering until runoff , then adding 20% more water. Most of the time it's just as quick not to flush , though. Hope this helps ! 🚀

Hey Growmie, It is the ph its off, for soil it should be anywhere from 6 to 6.5... 6.8 is too high. Hopefully I answered your question and remember Happy Growing and Free your mind one puff at a time.
