rusty looking leaves?

a couple leaves have this kinda rusty tint on part of it, this is the leaf its most noticeable on. I looked through site and diagnosis guides etc i cant really pinpoint it still,. can it be from too much nutes?? or a deficiency from not enough?? plant is like 4 or 5 weeks into flower
 
not positive about night time temp ha,. its usually bout 80 in the day, and i keep a space heater on in my room at night so i doubt they get under like 70 ish.. i hope its nothin bad its like halfway into flowering and this is my first grow i would hate for it to fail :P

It looks like a very natural purpling to me, based on the photo. Are the leaf tips normal? Usually, over-nutes at this stage manifests as down-curled tips in a claw shape. Could be cool night temps, esp if you have some "purple" genetics in your strain (and it doesn't have to be a brand-name "purple strain" to show this).
 
alot of the leaf tips at bottom and middle of plant are clawed down, but mostly just the fan leaves and random smallish leaves on the plant, none of the leaves coming from the budsites have this. but a couple of them hook sideways, and have a lil burn around the inside edge,.
ive only fed it nutes twice so far, what i got is a generic brand bloom feed its 15-30-15, i fed it at half strength the first time and a little more than that the second time. also no cluee what strain it is, heres pics tell me what i should do lol :D

Okay.. not so bad. You have a little bit of "the claw" from feeding high-phosphorous food during stretch, a high-demand period for nitrogen. Is that lowest leaf in the 2nd photo yellowing? That would confirm my argument. I did this last year, too, and if we had a nickel for every RIU'er whose done the same, we'd be outta here. A formula in some multiple of 3-1-2 is ideal for vegging on through to the end of stretch; the extra phos and potassium in a 15-30-15 can't be used, builds in the soil, and the plant has to give water back to the soil to balance the salts around the roots (so, those curled tips are little dehydrated areas).

At this point, stretch is over, and overall your plant looks pretty healthy. If you've fed sometime within the last week, just go with plain water for another week or so, then resume the 15-30-15 at half-strength once a week for another 2-3 weeks, then go to plain water the rest of the way. Be sure also, when you water, to water enough to get runoff out of the bottom of the pot. That will carry out some of the excess salts.

Good luck! She'll turn out fine; don't worry. My plants were twice as bad as yours at the same point, and they came out great bud-wise, which is what matters ultimately.
 
yah thanks kriegs, thats way helpful :P yah its yellowing, as is a couple other leaves down there near the bottom, one or two ended up drying up so i cut them off, before i switched to flowering i was feeding it this stuff that was 24-8-16, on my next grow would it be wise to continue that a couple weeks into flowering? also just out of curiosity as this is my first grow, what would a typical yield be for a plant the size of mine? even just a rough guess is better than mine at this point :P

Yeah; I go with the 24-8-16 until your height growth levels off. Measure it regularly; you'll see it drop off abruptly. That's your cue to go to something like the 15-30-15; it will be more like 4 weeks post 12/12 than 2.

Really tough to guess yields.. anywhere from 1-3 oz depending on light strength?
 
alright i'll remember that next time :) its on a 150 watt hps hung prolly 8-10 inches from the top, and a lil curly compact fluorescent on the lower side, i rotate the plant every couple days in hopes that the fluorescent helps the lower less developed buds grow

Cool, probably closer to 1 than 3, but hey, an oz lasts me forever and you'll see.. your own weed will be 2x as good as anything on the street.

I've done the HPS up top / cfls-down-low thing. It does make a difference if you keep it on the same branch(es) throughout, but otherwise not.

A lot of MJ plants will mature top-down. So, you can harvest the top half of the plant and leave the other half still in the pot. Chop your tops when they're ready, then lower your light down to the remaining lower half and fatten those buds up for another 2-3 weeks while you enjoy playing with your colas. You'll be amazed at how much that "air bud" will grow and tighten up once you take the top off. And I'll bet the electricity vs production equation is better than running a cfl down low for weeks and weeks, but with little gain in bud.

Here's a couple of pics. This is almost 8 wks, the better of the 2 fems. Almost lost 'em, but some first aid and a good flush has helped. They are regaining green color, tips are clearing up, and growth is getting vigorous. It's showing flower all over- raring to go. I'll flip it in a wk- 10 days. Have a male in the 12/12 rm getting ready to pop. I'll probably let a few open before I remove it, to seed some hashplant and NL x Sk that's in there, then save pollen for more KBerry.

Nice plants, but no one will see them hiding here in this thread. You can start a new one in any forum (New Thread tab).

Check out the seed tutorial under Advanced Cultivation -- it works great - I bred mine that way. And it will spare you the risk of releasing pollen inside your house and having your HVAC system transport it into your grow room.
