strange browning on the leaves. small buds.

ok, not posted here for a while as had to take a little break from growing to do some renovations.

and i have issues. as the title says, i have browning of the leaves and small buds.

growning a feminsed northern lights from seed. it in its 10th week of flowering. even tho the packet said 54 - 62 days flowering.
some of the hairs are turning, but most are still white, and the bud's are patheticly small.

ok, so what i;ve given it..

water, not entirely sure of the ph, but if its good enough to put straight into my fishtank without treatment, then i figure its the same for the plants, i do how ever leave a container of water to sit for a couple of days before i use it on plants. just to let any chlorine etc evaporate.

during veg, it gets only water, sometimes fishtank water as this water holds nutrients. but mostly "stood for 2 days" tap water.
during flowring, it recieves bio-bloom. by biobizz.
liquid plant food
(N) - 2%
(NH4) - 0.9%
(NO3) - 1.1%
(P2O5) - 6.0%
(K2O) - 3.5%

directions are 2 - 5 ml per litre with every feed.
however, because i grow in soil, i alternate feed / plain water.
started her off on 0.5ml per litre, slowly working up to max dosage up untill about 2 weeks before harvest.
currently on 2ml per liter.
nothing ever gets over watered apart from my house plants :/
the light is 12" / 1ft min away from plants.

i have 2 seperate chambers, veg & flowering. veg - has dual purpose (red & white) 300w cfl. flowering has 250W sodium bright & hot thing (i burned my bald patch ((on my head) on it last week whilst inspecting the plants). dunno temp's or humidity im afraid.

from what i can see, it has a deficency of some sort, but what i dont know. it acctually been shedding leaves from to to bottom.

the plant on the right, is a cutting from lefty lopez. (my nic name for it hehe) & i have more cuttings coming up from righty, 3 from 7 survived ish, just waiting to see if they survive going from rockwool to soil.

i added my finger/thumb into 2 pics so you get an idea of just how small the bloody buds are in week 10 of flowering.

hope i've given enough info to you all for someone to be able to help, sorry if im a bit vague on somethings. still learning & still aquiring the appropriate tools etc.

AD,
Some of the reasons for small buds are not enough lights, too much N, not enough P and K. Seems to me you have all those things to a certain extent.

Which picture shows the browning best. I apparently missed it. Maybe a close up shot of that area. An indica should certainly be ready for harvest well before 10 weeks so something is amiss.

john, 2, 4,5,6 but mostly in 8 u see the browning.

im thinking, maybe its terminally fubar! and just crop what i got before its too late? or give it a good flush, and once its dried a bit flush again. then dry a bit & feed just p & k?
i have a seperate formula which is just p& k, nowt else.

AD,
OK, I see what you mean. I guess by the time I got to #8 my eyes were tired! lol Do you see a pattern of the browning on the leaf tips. On that last shot, clearly the necrosis seem mostly on the tips. That usually means a burn from too much nutrients. Could that be? Are you using high doses?

About a month ago I was following a grow where the plants were burned toward the very end of flower. The trichomes had collapsed. And the grower wanted to revive the plant and get it to start producing trichs again. About a week or so of flushing, followed by a reintroduction of nutrients at a lower dosage...then more 12/12 time. Point being that almost a month later they were harvested. All that effort and very little gain.

I told you that story because, in a way, you're in a similar situation. Do you have a clone or a vegging plant waiting to go into flower? If it were my grow, and I was already two weeks over...I'd just flush them and chop them. Then give them a slow dry and a cure. Get what you can get and move on. Just saying that's what I'd do. Your choice.

I see Leaf tips curling up. You Have (k) Potassium Deficiency.
Flower will be diminished with lack of (K)
Make sure soil pH is in Range.

Good Luck on Your Grow, I hope you get things sorted out.

the second, bushy, healthy looking one is a clone, 2nd gen from the left pplant, which came from seed. i have3 more clones. 3rd gen, in seperate veg chamber.

but in all honesty, my neighbor had some of that auto-flowering stuff. it was ready Very fast, & he had good yeald. im tempted to get stuckin on a nice AF, was thinking tho, with the AF cuttings/clones, are they a ticking time bomb & ready up at the same time as the mother? or would the AF timer get reset in the plant till it reaches certain proportions.


few more pics, xbox pad for scale. or lack there of lol. took her into the bathroom, the light is a bit more crisp in there so makes photo's much easier to see.
yesterday, wednesday 5th was supposed to be my crop day of this plant. have now revised that till the end of the month.


as in the photo's in my first post, i have that second plant. the clone of this first one, 2 weeks in the flowering chamber & she's showing really nicely. something i have noticed tho...

anytime i grow weed, i get mushrooms growing in the soil. this isn't too much of a problem as the mushroom's break down the complex nutrient into simple ones, which is much easier for the plant to use. this plant im having trouble with doesn't & has never had any mushrooms in the soil. no mushrooms means a soil problem?

any who, i've been out & bought new pots to grow in. these are 30L as the ones in the photo's. but they're taller & square.
i have some (i think) 5L pots.

the cuttings, once healthy & established. will go into the smaller of the 2 pots. then again, once ready, they'll be potted on into the taller containers. is this right to move up in pot size? or once they're established in the pots they're in just put them straight into the tallest ones?

these are my 3 remaining, 3rd gen clones from the 2nd gen clone. & a pepper plant seedling i got space, might as well make the most of it.

also, had a look at the triclomes (sp) under a special microscope thing today. they're still clear, not even milky, so i've got time yet! so im thinking just feed it P & K for a couple of weeks, flush, dry & crop? its covered in triclo's, dusty as hell & extremely sticky / resinous to the touch. obviously i dont go fondling the hell outta my weed on a regular basis, had to grab it to get a decent look at it.

ADH,
Seems to me, to grow mushrooms in your soil, you must be overwatering. I've been growing since 1972 and never had a shroom pop up.

Hey, check the ppm and ph or your runoff water. If the ppms are high and ph low, you have nutrient salt build up. In which case, give her a flush and then back on the P and K after a few days. Something is causing those half dead leaves and that's a small effort that may give you some info.

2L of water a over 7 days. imho its not too much. only way i get run off is if i put 3 to 5L water into it in 1 go (growing in 30L pots) or flush it. i've already flushed her 3 times since this browning started.
she used to be as healthy as the smaller of the 2 plants in the first set of pictures.

will see if i can borrow my neighbor's, friends tester. he's got these digital ones you just dip in the water, think they're about £40 each or something, & i just dont have lump sum of cash in 1 hit like that. would do if i wasn't payin lots on electric. lol

will flush her again anyway, wont do her no harm, no more then she's already come to!
then leave her a bit to dry out then P&K the shit outta her?

ADH,
Well I wouldn't say PK the shit out of it! lol If your ppms come out really high and low ph, that means your soil has built up salts in it from too much nutrient. So go by the results of the test. If high ppm, then go easy on the pk. You don't want to burn her again if that's what happened already.
