Hey all and Happy New Year! First timer here so am asking for a little help. This Northern Lights auto girl is 6 weeks old, planted in FFOF in 3 gallon fabric pots. 2000 watt LED on 24 hours a day. Humidity is 50% and temps 70-80f . After the first 3+ weeks, I give her 1/2 teaspoon each a the FF Trio and 1/2 teaspoon mag every-other watering (4-6 days). I did some LST and appear to have a lot of Cola's/flowers. (is that what I'm seeing here? lol)
When I water, I add water until it just starts to run out the bottom into the saucer...usually takes @ 3/4 gallon. I then use a turkey baster to draw some of the runoff out and test it for PH and PPM (Is this a good procedure?) The last watering/feeding was 3 days ago the ph was 6.7 in/6.2 out but somehow, the PPM was 1200!!! I was tempted to flush it but decided to wait and see.
To my untrained and novice eye, it looks pretty good (?) but there is a little discoloration on a couple of the leaves. Are these anything to worry about? What does it look like to you experienced peeps?
Muchas gracias in advance!

The plant looks pretty good overall so I wouldn't be too concerned about that PPM #. Is the damage spreading to other leaves? Everything else you mention you are doing and environment conditions look good! Nice job.
Looks like possible phosphorus deficiency to me. Starting to flower the plant requires more for bud development. The half tsp may not be enough, I'd download and feed by FF and go by that, I'm certain it will be higher there dose.
