Yellow/Burn Tips-Everything Else Good-Day35 Flowering

The tips on most of my flowering plants were slightly yellow yesterday. Today that yellow is mostly yellow/burnt. This has begun on day 30 of flowering...

Here is a shot of them: (2 ak48's in back, 1 big white widow, 1 small white widow in soil to right).


Heres some of the leaf tip burns on the white widow:

i think u might be a little bit too critical if u ask me my friend, from the looks of the pics it doesnt even look bad, theyre barrrrely yellow at the very tip, it could be anything...if it bothers u that much u could always just flush them with a heavy watering and serve up the nutes after the flush in a lil less dosage than usual and im sure the beautiful green will come right back...long story short, i wouldnt worry about it 2 much...its when people try to figure out EXACTLY whats wrong that they mess up IMO, if ur a new grower just let the plant do its thing, its a weed and very resilient, dont forget,lol.....good luck

Yoour gonna over feed and kill those plants, thats not the problems the salts are just gonna build up, your problem is PH if the PH is not perfect it will not absord all the nutrients and will cause you to think feed it cuz its a deficiency well this isnt always the case check PH first

I'm not freakin out~ But when my plants go from no issues to obvious yellow/burnt tips in 2 days, and I know it's diagnosable, I just wanted to solve the problem since today is my res-change day Instead of waiting a week, that's all~

I re-calibrated my ph meter, seems a little shifty. Will be investing in a different one after this 1st harvest.
