Been growing this girl a long time. Basically perfect leaves until recently. You can see in the pictures below the leaves have very recently gotten a yellow tinge. Anyone know what deficiency that might be?

Thanks!!!

So Tint, originally I was using General Hydroponics 3 part mix plus CaliMagic. But I ran out of that, so I switched to using a mix of Miracle Gro (the bloom booster kind - 15-30-15) and Calcium nitrate and Magnesium Sulfate. In like 2 to 2 to 1 ratios, respectively. I believe I used a table spoon, table spoon and one-half a tablespoon, respectively, in a 5 gallon container of dechlorinated tap water. This switch could be causing it. Thoughts? Excess PK could indeed be it, particularly the P with the 30 rating. But I dunno.

Thanks so much!!!
 
If I were to make any recommendations to new growers....

1. Digital PH Pen - Bluelab or equivalent - no cheapie!
2. TDS Pen - HM Digital or equiv. (Amazon)
3. Simple mainstream nutrients. (plenty of support!)

Seems like too much N throwing off the K n CA....it happens! Im almost sure of it.

How many weeks into flowering r u? Im guessing 4.5 to 6.

I used fox farm once. Going by the bottle will over do it big time. Those plants in pics are

small to medium in size. 1 to 3 feet in height. Ive heard to use from 25% to no more than

50% of what the label suggests.ill net your ppms are close to 1200 1400?!?

Not tryin to bash you and be a dick. Thats way too much fertz

3 gallon pots
Feeding 1.8Ec @ PH 6.0, once every 3 days.
Temps low 80s.
Humidity high 30s.
