Nute Burn? Or Something Else?

She's a purp strain, planted on 3/12/2011 (Making her ((hopefully her)) 16 days old) she started in a 16oz cup, and I transferred her to a pot on 3/25/2011. It's the same soil she sprouted in, so i'm curious why her bottom leaves are wilting. Is it just not enough water? I put her on the same schedule as my other babies (4x 100% Indica Master Kush Clones) so, perhaps it's just not enough water for her. The soil DOES look dry, but it's watering day, so if it's dehydration i'm gonna know it REAL fast, but it was sorta happening before this too...

Anyway, here's her life cycle pictures so far.


Now, that's he(r) so far up until 3 days ago, and THESE, are the newest ones I JUST took...




Lemme know what you guys think, it's prob the most SIMPLE thing that I've overlooked.
This, and my 4 others, are under 13x 26W CFL's, 4x 5000K 1660L, 9x 6500K 1600L. They're all in FFOF (cept the one above, she's in Miracle Grow Potting Soil (ran out of FFOF after I planted the 4 clones, found a purp seed after that and planted it, unexpectedly, she sprouted, ive decided that if it's a female, I can clone an ARMY of purp plants, and if it's a male, I can harvest some pollen for future use, never know when purp genes may come in handy

Just for the hell of it, heres my 4 100% Indica Master Kush Clones as of 3/28/2011 @ 7:00 AM Pacific Standard Time. Lemme know what you think of them too

C1 - Tallest so far, she's growing quite fast.




C2 - Was Topped by the guy I got the clones from, so she'll be growing into 2 main colas




C3 - Is the bushiest to far!




C4 - And finally C4, the problem child...because she was topped before I got her, she's been kind of stunted since she hit the soil. She was the last to be planted, so I wonder if that didn't have something to do with her stunted growth. She has HOWEVER, in the last week, recovered VERY well and has made a pretty full comeback, she's just playing the catch up game now!


I'll prob start a grow journal, so I can update the 4x MK clones for anyone who's interested...But for now


Back to my issue of the yellowing/browning leaves...
Should I cut off the affected area of the leaf?
If not, what suggestions?

Thank you in advance, and +Rep for answers, although if your like me...you don't do it for the rep, you do it so's that plants don't need to suffer needlessly @ the hands of noobs!!

hey dude have you any info on your waters ph ?? what is it going in at and what is it coming out at around 6.5 is great for soil and if its miracle grow soil its very strong with ferts that could be doing the damage! what are you feeding them how much so on more info on the feeding.

looks like a bit of nut burn. ur others look VERY green from what I see in the pics, watch that u r not giving too much N. do not go by the top soiil & how dry it is. u have to get used to water by weight, which is the best method. when u water ur plants, water them until it drains out the bottom, then set them down. a minute later pick the container back up & make a mental note of how heavy it is. Now when u check ur pots in a day or two, & lift them again, when it is ready to water u will notice a big difference & u will see how light they are. when they r light again, it is watering time. and no, dont cut ur leaves, it is unnecessary.

p.s dont go cutting anything off give it time you dont want to stunt growth even more.

She gets 8oz of pure RO water @ a pH of 5.8-6.0 or so as recommended by the guy I purchased the clones from, he's grown these strains before, so i'm taking his word on it, the purp one tho (which is the one with the problem i'm asking advise about).
I haven't tested the pH coming out yet, because they're in the same pots they're gonna flower in, so 8oz isn't enough to flush all the way down to the bottom, i'm just surprised she's getting burned NOW, since it's the SAME soil she sprouted in either way, if I need to I can always flush the soil, i'd just rather not have to replace nutes if they're not whats causing the problem.
The temp stays between 76-82F, and the lights are never close enough to touch.

Odds are, i'll prob end up getting some more FFOF and transplanting it when it's a little older, so it won't be to young, so as to get nute burned, and I won't have to worry about this Miracle Grow stuff anymore, I really wish I'd just sprung for some FFLW to sprout her in, then transplant her to the Ocean Forest.

Haha, thanks, and yeah, currently the clones are getting all their nutes from the soil, it's day 18 and i'm just letting them feed on the FFOF, and because they're in a temp spot, I can't flush them (water til it's coming out the bottom) each time I water. I've however been steadily increasing the amount of water they get each watering, and wait between 2-3 days between waterings. I do go by weight, but weight after I water vs weight 2-3 days later, when I KNOW it's dried out. I also have a soil moisture meter, but it's a piece of shit, so I really just go on weight, thanks for the quick answer!!

sounds like your doing things right my bet is that its the miracle grow soil although i do believe ph around 6.5 is best for soil or so i have read. give the pot a flush and see if it helps hope things work out dude. peace

Thanks a lot, I really just wanted a few opinions on if flushing was the right answer, and of course for ppl to tell me how great my Master Kush clones look

I can't flush them (water til it's coming out the bottom) each time I water.....

remember, this is not flushing. u should be doing this everytime with every plant so u dont have salt buildup in the soil. flushing is putting 3x-5x the amount of ur container with water through the plants. overall u r doing a great job & the plants look good

Thanks!! ^_^ I really can't hear that enough
I was simply watering them as per the instructions of the guy I bought them off of as far as the watering goes, but i'll try it, as long as I can make it work in the area i'm using.


And regarding the problem, i've flushed her pot out, and I took a pH reading on what came out the bottom, it's only 6.2 or so, so it's really no different, or if at all, VERY slightly higher then when it goes in. But the miracle grow I'M SURE has to high of a nute content for such a young plant, anyway, now that i've flushed, i'll let it dry back up and we'll see how it goes!! Thanks for all the help!!

do you add cal/mag? using r/o removes cal/mag and iron, you need to put it back.

I'd never heard that about RO...but since the 2 weeks is officially up, I was about to start adding Veg nutes to the clones, i'll wait another week or so on the youngling.

r/o gives you 0 ppm's all the stuff you need is also removed, get some cal/mag+ or magi cal and start using it, you should see her come back.

Well i'm hoping a good flush will do the trick, if I don't seen any improvement in a day or 2, or it continues to spread, i'll have to pursue other avenues...
But that's good info to have, I'll make sure my nutes can supply both elements in sufficient quantities. Thanks again!!

Worked great, she's growin like a champ now with no further yellowing of any leaves.

good stuff glad she going good again

Older post, but a quick update, it WAS a she as it turned out, female all the way
And since posting this thread, i started a grow journal which is in my sig.

soil ph should be around 6.5-7.0 Hydroponic is 5.8-6.3

always nice to have a follow up, glad the plants r doing well!

See, I hear what your sayin, but my journal tells another tale. I've had them at an average of 5.8-6.2 pH since they were soiled and they're thriving. I'm not saying your WRONG, not at all. I'm simply saying that, what i've been doing works.
