the two on the left seem good but the one on the right has a couple leaves dropping off now and again.
is this pretty normal? I'm 5 weeks into flower and I heard fan leaves drop off as I get closer to harvest.
after noticing the yellowing a few days back i read it could be a magnesium deficiency so I added CMX to their last batch hoping to fix the issue but any and all advice is welcome
Thanks all!
Peace

Welcome and good luck with your grow.

Generally your plants are looking good. I would think that the leaves with the yellowing in between the veins looks like a Magnesium deficiency. I would supplement with some Cal-Mag at a rate of about 20 mg per 5 gallons. If you don't have any you could add 1/4-1/2 tsp of Epson Salt (magnesium sulfate) to your nutrients.

As your comes to it's natural end as blooming continues you will wee some of your leaves starting to yellow and fall off. This is natural.

I think your are in good shape to complete your grow even with the deficiency.

BUMP. I thought it could be calmag. Ive heard flowering plants burn through a fair bit of calmag.

But yer doesnt look too bad and your plants cant be far from the chop so itll start paling reasonably soon anyway.

They look good...plants that late in the game have yellowing leaves, especially those big fan leaves down low (which I usually clip off 2-3 weeks into flower to save/divert for the flowers). You could clip them off now also...

"5 weeks into flower" doesn't really tell the grow timeline with autos...I usually runs my autos 1-3 weeks after the "breeder promised" date. You look like you have another 2 weeks easy, and people that use nutes stop 1-2 weeks prior to harvest.

Also recommend that you properly cure them for 2-3 weeks before try them...it's hard to wait, but you'v given them so much time and attention up to now that a few more weeks will be worth it (and your buds will repay you for your patience!)

They're 9 weeks from seed as of yesterday. not sure how else I can gauge it but if I should give an extra one-three weeks then I've got another monthish to go, I can deal with that!
I'm going to get jars and use humidity packs to perfect them, my first I want it to be top quality as I'm not sure when I'll be able to do my next one.
Thanks for info and happy growing!

Give them at least 2 weeks...they will double in size.

do you think this stuff I found called CMX will do the job?
CMX I've given them the recommended amount this morning so hopefully it's just the time for them to starting shedding! Thanks for the advice bro!

no way? Haha I was thinking they were nearly done with growing. can't wait to see fatty buds! Thanks a lot blew!

 

[Blew Hiller]

Personally I think your plant looks fine...if it were me I would trim off the lower large fan leaves (which will save remaining nutrients for buds) and just make sure she gets enough water...she is almost done and she's looking good so just cruise past the finish line.

Yes, they will fatten up and get more resin and sweet smelling and delicious...

Looked it up an CMX would work fine. Your plants will need Calcium and Magnesium especially as you get into bloom.

it this the same sort of thing I can't use 2 weeks prior to harvest? will it give them a funky taste do you think?

Get it for the next grow....skip it for this one.

No problem. Next grow consider starting a grow journal. Good way to get lots of great advice and encouragement.
