So I believe I’ve had nitrogen deficiency all the way up into week 7 of flower before I realized why my leaves were turning yellow before my flush so question here is can it kill off random buds because I’ll go check on my plants and randomly will have buds dying off and it doesnt look like pm or any type of mildew and Ive noticed the buds that do die off will have yellowing leaves first even sugar leaves then the whole buds eventually dies off after the leaves but like I said the bud will be perfectly fine just over dried because of course it’s under the grow light until I find it and cut it off can someone tell me what’s up here it has happened before too in some of my other harvests btw I did try cal mag and it seemed to slow down yellowing

Welcome to the forum! Any pics? What medium are you in? What's you're runoff pH? What's your runoff PPM? What are you using for nutrients and how often are you feeding? How often do you give CalMag? Sorry for all the questions but more information is needed in order to help properly diagnose.
I’m in soil was Having huge ph problems because the person who I learned from told me not to ph because i was running soil but that could be so much farther from the truth so I tested my run off at 9.4 ph and flushed got my run off down to a 6.2-6.7 range and I feed about once a week and I only used cal mag 2 times so far thru this grow only because I was trouble shooting my problem my ppm was 2200 before flushed I just measured it the other day and it was 1265
@mwhite9829 thank you for the feedback sometimes you can feel lost when stuff like this is happening
So you're in week 7 of flowering now or week 8?
Now I’m in week 8
@bkush412 When will you be harvesting? With it being so close to harvest, there's probably not much you can do; it may be best to ride it out and then make changes next time around.
@Mr. Grow It so today i ph my run off just for fun and found out my ph is at 7.6 coming out and Ppms up to 1900 so I need to lower my medium ph shoulda checked that first but I figured I had that under control since I was phing and wasn’t before I guess because I didn’t water in at a lower ph every time and let it vary from 6.2 to 6.8 now I’m gonna just start watering at 6.0 for here on out till harvest we’ll till my flush which is only 2 weeks away im on day 56 of flower
Just outta curiosity, are you testing your runoff from dirty trays? I know when I check mine, I make sure to have a clean tray underneath so as not to get dried remnants from last time. You know what I mean?
