Having trouble keeping my leaves green

On week 6 of 12x12 my plants have been a lush green up until about a week ago they started to fade to yellow. I upped their feedings to include more mag and N but I'm not sure what else to do. Any help would be much appreciated.

Here are pics:

Sounds pretty normal to me, albeit a little early. Some strains do though. I have a cut of thseeds lambo that drops most of its leaves pretty early.

Go easy with that N or you'll make it foxtail and it'll take longer. With a bunch of dead leaves that can be an issue. (Been there)

If it's your first grow with that strain I would continue as normal and see what happens.

They're hungry. The pots look a little small for the plants to be scrogged out. You're asking a lot from those girls.

You see all those tiny underdeveloped budsites in photo 3? Those are sucking nutrients away from your main buds. Try cleaning up more of the under canopy next time or a larger pot.

More roots = More bud.

Doesn’t look like an Mg issue, maybe N deficiency.
More info would be helpful.
Strain
Soil
fertilizer history, type, frequency, strength/EC.
pH.

Strain: A-Train
Medium: Promix HP w/mychorrizhae
fertilizer history: during veg they just got miracle grow. In bloom they are on pH perfect products with Sensibloom A&B being the base. Additives include B-52, Nirvana, Bud Candy, and Big Bud. They are generally ready to feed every 3-4 days (5 gallon pots)
pH going in is usually around 5.9. My EC meter is broken unfortunately. Sent out for warranty repair for the time being.

This is my first grow with this strain yes, but also only my second grow overall so I am still very new at this. Thanks for the tip.

I hadn't thought of the pots being too small (5 gallon pots). I'll be more mindful next flower cycle. Thanks.

When did you switch to the AN Sensi?
Right after switch?
How long after you switched did you see flowering?

I continue with grow fertilizer after the flip for a week or two easing them into the new fertilizer. There is explosive growth at this stage and that requires N. If you switched right away I’d say you starved the plants of N when they really could have used it. Like Antitheist said be careful trying to compensate for it now.

The bloom phase starts when you see hairs at the bud sites. . If you flipped 6 weeks ago you’re really in like the 4th or 5th week of flower.

If you are using the recommended rate of AN Sensi and the other stuffl, the your NPK ratio is 1::0.6::2.0 at 713ppm. I like to try to be at a 3:1:2 ratio of NPK in veg and the first week of two after the switch easing to 1:1:2 NPK In bloom and then 0-1-2 toward the end.

I left them with just miracle grow for the first two weeks. I began to see buds about 5 days in.
 
They are hungry. I would say your pH is off. Double check your pen, calibrate it. If your pen is fine then I would say you shocked them a few weeks back.

Promix should be run at 6.5 pH

From what I gather, it looks like you went to bloom feed & bud candies too early and they are "stalling out" early from lack of Nitrogen. Lots of folks think they should be switching to bloom feed right when they switch, when they should really be feeding veg feed until stretch is about done or completely done (usually 2-3 wks or so into flower). Some will do 50/50 of veg & bloom feed during the first couple weeks of flower, then go to full bloom feed once stretch is done. Then the bud candies etc from weeks 5+. As far into fade as you are, I would just ride out the normal bloom feeds. As mentioned, I also believe its too late for the N/Mg bump and all that will really do is cause foxtailing and/or lockout at this point.
