First flower cycle need help!

Need info. What fertilizer, how much, room temp/humidity, what medium (if soil what type).

I vote potassium and cal mag. All cations. Interesting.

I'm not sure y but looks like the thread was duplicated.. Anyways here's a copy paste from the other thread.

I'm not all advanced yet either obviously. I agree with flushing. however it is in soil id say mid flower cycle (finishing 3rd week) some leaves are yellowing (older fan leaves mid to lower plant) and over all they're starting to look a little pale. If I flush even with adding a light nute to the final volume of water would that make the yellowing or paleness worse? I realize the absence of nitrogen is more than likely the reason. I guess I'm just affraid to flush at this point. I appreciate your insight. Just weighting the options trying to get these girls to the finish line.
Flipped 3 weeks
Ffof soil
Ff nutes
Temps lights on 70-75 rh 40-50
Temps lights off 65-70 rh same
No gas (not yet) I'm sealed for it however I vegged too long being a newbie wanting to perfect everything and I didn't want these ladies getting too excited in stretch)
Anyways thanks again brotha any and all help is always appriciated.

One more bit of info
Last feeding Sunday 6.8 ph 900 ppm tiger bloom, big bloom, beasties bloom, and a touch of grow big (fox farm soil schedule week 6) under 1/2 strength.
They're due for plain watering tonight I'm planning to feed again on Sunday its been their routine.

When you say you "believe in flushing" you mean the toilet after you have had a dump right?

Find me any reference to "flushing" in a horticultural text book. Just one.

I agree with flushing.
As in if my dudes theory is correct and the leaves are showing nutrient burn maybe a flush to reset the medium could help.
However I am skeptical its too late in the game to be pissing them off. I feel anyways so long as the issue doesn't worsen I'm going to stay on the beat and path.

I posted for insight I'm new I'm not ashamed to ask. I'm caught between feeding too much or not enough. Buds look great and are forming quite nicely. However inexperience breeds uncertainty id rather error on caution and add extra rather than wish I didn't do that while watching them go up in flames.

And yes I flush my poops too..

What's your runoff PH?

6.8 feed PH is on the high side - I'd stick with a low 6'ish PH. You're probably seeing some K lockout from the PH being higher than she likes.

Ill grab the run off ph tonight when I water. To check that out
I can add more cal mag but that's another rock and hard place. I'm only using a tall boy filter ppm around 200 out of the filter I'm sure most is cal.

Good point..
I was running 6.8 as a rule in veg so I just carried over.
Run off wanted to stay low like 6.1 to 6.3 (in veg)so I countered that with the 6.8
I was reading about how its opposite in flower the soil tends to drift to higher ph. is there any accuracy to that? I guess ill find out in about ten minutes lol
And thanks higgs I do appreciate it.

Its more indicative of K than anything else, I think. Magnesium is a possibility too.

I'm 4 weeks into flower and it seems to vary somewhat as to which way it want to pull. They started pulling up for a bit, but now its more downward. I've just been keeping mine aroun 6.0-6.2 lately, mainly because my bloom nutes are so acidic its hard to get it much higher with out getting a precipitate.

I'm thinking your exactly right. Ill post the run off in a little they're about to wake up.
I can bump the cal mag up to 5ml a gallon just I was always going with the low 3 ml per gallon due to having 200 ppm water to start with.

Run off 6.5
Clear water too
I'm leaning twords I fucking burned them again
So if I just water enough to grab run off is that sufficient ? I really don't wanna put them through 12 gallons of water at this point unless I have too. Maybe water them with plain PhD water and cal mag once more before feed again? It would screw up their schedule id hate it but id hate having bad bud too...

I would not do a flush at this point, I would just bring the PH down a little and watch to see if she likes that better.

Right on
Thanks man ...really thanks.
