Being my first grow…i have a couple questions:
Starting my 7th week of Flower, from 12/12 switch.
1.) If you look closely at the White Widow (On Left), is it just turning colors, or do I have a Phosphorus Deficiency? Same with Cali OG Kush Haze (on Right)…some red on the leaves has me thinking Phosphorus issues?

2.) My PPM’s come out higher than when I water or feed, by 300 PPM’s or so higher.

I’ve had some very slight Nute burning on Tips of Cali OG Kush, so I’ve backed off the feeding
to 600 PPM’s…still keeping the White Widow at 830 PPMs

I’m using Cal/Mag with every watering and feeding.
I water til Runoff everytime (15-20%)

I Water, Water, than feed every 3 days.

Question—Should I be flushing to get the PPM’s down, so that they are same or lower in the runoff after I feed? I kind of don’t want to flush, and was not planning on flushing.

Thanks very much in advance!


Ok so…

First, LOVELY PLANTS! Everyone looks frosty funky n sticky.

Next, i dont see a deficiency Clearly. Looks like just fall colors (temps hitting the 60s would do it). No extreme worry there.

Finally, id keep feeding a tad longer. Maybe begin to watch trichs, but this is the good part. I always make sure to feed until they stop eating. If she’s still consistently the same poms in ppms out difference wise? Then ur hitting the nail on the head.


Agreed! For your first go you’re killin it!!


Great looking ladies. Welcome to the neighborhood :grinning: Have a fun and happy Harvest.
