Hi guys, im 3 weeks into flower and just did a big 1/2 cup of flower girl (3-9-4) about a week ago (3 gallon). Starting to notice some yellowing of a few fan leaves, but its near the buds and not on the bottom of the plant. I’m wondering if this is a deficiency or if i should let it go. It does seem to affect like 6 fan leaves.

maybe mag?

It just doesnt have that nitrogen YELLOW that i see from pictures. Its interesting that its literally one fan leaf off of every cola that it is showing on, not just all fan leaves equally.

bump. Might give more mag cause i find it odd that it looks really healthy but some fans are turning, suprising given the recent top dressing

That flower girl is going to take a couple weeks before it starts to break down.

Starting to see more “light green” old fan leaves... it stopped stretching awhile ago, not sure what it can be. Hate to feed it more nutes, but doesnt look like any common deficiency

Deficiency, flower girl is a organic slow release fertilizer meant to be mixed into the soil/potting mix directly. They say you can sprinkle it on the top and "scratch it in" but cannabis plants grow too fast for those type of fertilizer to work properly. If you want to go to the organic route either mix that stuff into your transplant container before flower or feed a liquid organic like Green Planet Medi-One or General Organics BioThrive etc..

It's your pH. The ammendment you added is breaking down to it elemental form and your pH is off due to excessive bacterial exudate. Organics work because both bacterial and fungal presences influence a harmony and it reflects in the pH. Add food of an organic source to healthy and thriving soil you'll have an explosion of bacteria breaking down the food source. Fungi can't work as fast as bacteria.
Adjust your ingoing pH to drop that of the substrate. Reflected in the runoff reading

I top dress with Gaia green all purpose and Gaia green power bloom all thru flower and it works great. Not sure where you getting it doesn't work.

It has to be done at the right times or you will end up with deficiencies. I start flower giving all purpose and everytime I top dress add in more power bloom as flower progresses, by the end I'm at full strength power bloom usually. It's surprising how long they need veg nutes in flower.

Definitely needed thru stretch, then taper off thru thru the rest of flower, as you stated. Seems to be working for me.

You're likely mixing it in at the right timing though, most new growers will mix it in like they would switch to a bloom fertilizer in hydro or soilless. I know first hand because my friend tried it with M3 soil and the plants were deficient before they finished due to the small container size and growing start to finish in 10 gallon pots under 1000w MH in VEG and 1000w HPS in flower.

Um.... yea.... top dressing at the right time, is kind of the idea. It's not a secret that organic matter needs time to be consumed, and converted into the nutrients the plant needs. New growers would have a hard time feeding bottled nutes, without following some kind of feed schedule. Same applies with living organic soil, it's just a different schedule.
