Looks more PH related in my opinion, although the rest of the plant is largely healthy- and it's hard to tell under the blurple light. Do you check your runoff PH? Input PH?

CalMag or PK issue?
What is she telling me? Before I was thinking of a CalMag issue (upper leafs have "burned" tips and get yellowish). So I added it to the reservoir. Is it CalMag or maybe a PK issue, that resolves in a CalMag issue? See my diary for more details.

Issues with leaves. Day 90 total, 30 of flower. Leaves have been getting more and more yellow the past week, with progressively more brown tips.
Vpd has been pretty close to ideal, the pot had 1 gallon less soil so could be missing out on some nutrients? Possibly Potassium? Otherwise not sure what it could be. Does not appear to be N deficiency because the leaves are affected from the top too. What should I do to fix this

Need some help asap
What is wrong with her? :( I am assuming N Deficient, but I also have veeeeeeerryyyy lightly burnt tips so it is confusing to me. The lime-greening of the leaves makes me think N Deficient though.. Any thoughts? I have some new nutes on the way should be getting here tonight too.

The leave tips of my plants turned yellow and burnt after i gave them a bottled nutrient feed (organic). Unfortunately i failed to measure the PH of the Water (it was probably to high). This was one Week ago and the New Growth still show signs that something is wrong.

Is it time to flush or wait a week?
Hey what’s up grow gang, we’re approaching the final weeks of flowers, but I was curious as to if our grow is ready to be flushed, or if they possibly need another week of nutrients, and also the best flush technique for best results. Thank you for answering in advance!
