Yellow/brown spots, 3 weeks of flowering (yes, another one of these!)

The plant is huge, there is something like 5 tops on her. The budding looks great. This is my first grow, I think I've done pretty good to get to this point. I don't want to fuck up now, though.

It's hard to determine what to do because on one hand I read all these things about too many nutes causing "lockout" and then you're telling me there isn't enough nutes, haha. How do you tell the difference?

Is this all per gallon?

right, correct, sorry.

I should note it says to always add Boost first. I do that. It also says the PPM of the solution should be 1430, but when I test it usually is around 900-1100. I always figured since it was less it was okay because I feel like I'm erring on the side of caution.

This confuses me slightly.

I will get there, just need a bit.

Do your leaf tips ever curl under or appear crisp/brown?

Only on the dying leaves towards the bottom, which I find 1 or two of laying in the soil every day.

Aside from that and the brown/orangish "freckles" on a lot of the biggest leaves, no other issues really.

Leaves falling off and dying from the bottom is typically a sign of a deficiency. To be honest though, I don't see how you are getting one with what you are using.

Does your ppm meter use a .5 or a .7 conversion? If you're not sure, research the model and let me know.

Damn that's a lot of stuff to add... Personally I think it's something to do with your PH. I also believe it has something to do with what was mentioned above with switching to full flower nutes straight from veg. IME I would suggest switching your nutes up slowly by mixing 1/4 flower nutes to 3/4 veg nutes and transitioning my way into full flower nutes. For me this way helped me dial in my transition percentage wise and it also helps keep those leaves green much later into flower. If you are already doing this and I missed something I apologize.
Do you check the PH of your runoff? I suggest checking the runoff of both of your plants and comparing them. As you suggested some nutes are locked out at certain PH so IMO I would start there. If your PH is good then I would say look at your nutes, maybe try a little veg and less flower. Good luck and happy growing.

I've never tested run-off pH, if I want to do that how much run-off should I get before it is considered adequate for testing? Also, what reading should I be hoping for?

I like the 1/4veg 3/4flower nute idea.

I have a soil pH tester, it seems to be working. Reading is usually 6.8 or so. Normal for soil?

Interesting bit of info about the ppm meter. How can you tell it is being converted @.5?

The girls are all sleeping right now. at 1am EST the lights flip on. I'll thoroughly inspect and take pictures of her then.

From what I can remember, I don't notice residue per say but the water run-off is usually a tinge of brown. Slightly.

Perlite sits at the bottom of the pot and sometimes a bit falls out, but any "salt" or "residue" appearing? I don't know. I'll look closely tonight.

Pretty sure my meter isnt @.5 man. Instructions read 0-999 it reads like normal and if its 1000-9999 there will be a x10 symbol flashing.

I see. Sorry. I didn't know there was some kind of conversion factor involved.. and I'd never heardanything of it before. You would think they would label that clearly..

It's all good...Check this out:

http://www.angelfire.com/cantina/fourtwenty/articles/calorama.htm

At the bottom, you can enter your reading in the .5 conversion space and press convert. That will get you to the .7 number.

Check the bottom of those pots, especially the drain holes and see if there is any build-up.

oh, that is helpful indeed. What do I want to convert to? .7?

EDIT: Let me rephrase that; is the recommended formula on these technaflora nutes written @.7?
