title says it all....

My first inclination is just N def. after the stretch she might have used up what I had been giving her... the purpling stems make me think P def....i water 2-3x weekly, when the soil is basically bone dry...she had about an 8 week veg, so it could be root-bound at this point also. I did miss a watering 10ish days ago, and she was severely wilted, but bounced back in a day. My ph in and out is between 6 and 6.5 with RH a bit high between 40 and 60%, but i've got a nice big fan helping out. High daily temps of about 78 or 79(usually around 75), dropping to 69-72 at night when my lights are on. Cola development seems to have slowed some, but not entirely...oh, one other thing I noticed was that some of the white pistils, are either "browning or amber-ing" in a few spots, no real rhyme or reason to that though, some are the lower buds and some are higher on the plant , and not necessarily on the branched that have yellowing leaves.

feedings every other watering. Been easing off FF Grow big, but gave her a bit more than usual yesterday hoping to give it some N and P. Also using FF big bloom and tiger bloom, basically according to directions.

I just dont want to burn through all these fan leaves before the last couple of weeks when she will really need those nutrients. I'm going to upload a couple photos, but the best ones were taken with the lights on...ill try to update later tonight with some more lights off photos to give yall a better sense of the "splotching" and changing of the leaf color. The rest of the plant is a fairly dark green and appears healthy without cupping or clawing or sagging etc.

Thanks for the advice @Bernie420 ! I finished dinner and went ahead and pulled the yellow guys as you suggested...i've heard that letting the dead ones fall onto you soil is asking for trouble. So, do you suspect a Cal-Mag issue? Ill give it the epsom salts tomorrow or the following day with her next non-feed watering. I also have some dark molasses, which I understand has some calcium benefits(correct me if i'm wrong)...should I dilute a tsp or two with the salts?

Thanks again. This is a really good forum, and I cant wait to feel confident enough to be on the other side of this coin, offering advice, and contributing to the same group that helped me!

Here are a few more photos, lights off....i took a final photo of some of the leaves i pulled, thinking it might give additional insight into the progression/different stages of progression.

My decision to take a tolerance break until this is harvested and cured is proving more difficult than I thought... this plant is stressing me out(in the best way possible) hahahahaha

I learned that molasses isnt the best thing to use although I use it a couple of time in veg,,, then the last two weeks in flower is ok to use molasses. To keep the microbes active and fed.

So right now no on the molasses. Not a cal mag issue to me looks just mag, also the big spots of brown might be a phosphorous issue you had in the past I wouldnt try to correct that now. The top growth looks good. You need to know that the plant loves the mag so its almost always a mag issue first then the next problem most growers get a potassium issue.

Also to me I dont grow with an led and I think that they just suck the mag out of the tops of plants before the plant has time to translocate mag from the lower leaves to the top, even a cheap led imo does this, along with most dont use enough mag to begin with.

That's phosphorous deficiency. Better get it straight quick. You are about to hit mid flower and will need more P than ever. Should be on the bloom nutes right from flip. Sounds like you are in soil. If that's right your ph is too low, especially to fix a P def. Start giving full doses of bloom. If your going to use the FF flower nutes, use both the tiger bloom and big bloom together as recommended. Get your ph up to 6.8.

Mars Hydro ts and sp series already release, welcome to try them to get a happier harvest~ :bigjoint: :bigjoint: :bigjoint: :weed: :weed: :leaf: :leaf:

No hate here MARS HYDRO....Ive been really happy overall with my reflector...i think that the reflector series is great for what it is(older blurple style)...particularly coming off a 400HPS/MH...ive had my eye on the TS or something similar. FWIW, the thing that has stopped me from getting one already is that if i'm going to setup a 2nd tent, i would like to have a more dialed in spectrum...it would be awesome if yall had a "veg" TS that leaned heavily to blues and a "bloom" ts closer to 3K overall...

we can take ts 3000 as an example.
the spectrum is the newest and popular sunlike spectrum which are simulated to natural light, the perfect spectrum for the whole grow cycle,
welcome to check the item #ts3000 for more details; it includes the spectrum you mention. and also includes IR led which are good for flowering.
wattage can be adjustable by the driver.

I might be tripping but it looks like PM in the last pic on the first post and the last on the second post.

If so, I would pull as much of it off the plant as possible. To late to spray green cure or anything in my opinion.

That is PM in the last photo. You need to defoliate and strip away any leaves with PM asap. I would also raise temps, lower humidity and even consider adding another remedy e.g. greencure, PM wash, homemade remedies, sulfur bombs.

Yeah, you guys are right...im on it...did a major defoliation, and have been giving it h2O2 sprays once or twice a day...i'm absolutely butt-hurt about this....it's not near the bud sights up top yet which is some reprieve, i have my fan on full blast 24/7 and am putting in a small heating mat to raise temps a few degrees. New dollar tree closet dehumidifiers going in(those charcoal/silicate absorbers). hope the entire thing isn't shot...thanks for looking out... @xmatox @nurrgle
