Leaf edge yellowing during flowering

I am a few weeks into flowering on a Gold Leaf and I am starting to get yellowing/browning of the edges of leaves, see picture. I use Tiger Bloom and CalnMag at the recommended dosages for general feeding. Thank you in advance for any comments or suggestions.

Will need runoff numbers, light type, nutes fed, all info you can give, but looks like a pretty bad potassium deficiency to start.

Fox Farms is a 3 part fertilizer, if your only using Tiger Bloom, your not getting a balanced feed, the Big Bloom is full of micros your plant needs. Grow Big supplies nitrogen which they still need in flower too.

Thank you for the help. I’ve never measured runoff numbers before but I do have a TDS meter, is this what you mean?

Yes. Tds/ppm

@ carnot12 Looks like ur plant is begging for Potassium.
