Hi,
It's my first grow in soil, I'm in week 5 now of flowering.
Mainly white haired buds now and very small areas have brown/yellow color so there is more way to go.

My problem is that my plant have some leaves with small brown dots and most of the leaves are burnt tips that go upwards (from last week).
I had before some leaves with brown small dots(even in veg period), mainly on big bottom fan leaves that eventually turn to yellow and die(I thought that not too much light so this is the case), but it's spread out quickly in the last week and I see more symptoms like:
- Purple stems of fan leaves on top get more and more.
- Small brown dots increased on leaves and also came up.
- Top leaves turn to dark green and are not so soft, also curl sideways down.
I added some pics that you can check and help me.
I thinks also that buds are not so big, but I'll let you decide.

I'm using 4 x LED bulbs 26W each (2,450lm), 12/12 light schedule with complete darkness.
I'm using BioBizz nutrients, my last 4 watering as follow (ml per liter):

WEEK 4 - 31/10/2016 -
BIO GROW - 2ml, ALG-A-MIC - 3ml, BIO BLOOM - 3ml, TOP MAX - 1ml.
WEEK 4 - 04/11/2016 -
Same.
WEEK 5 - 08/11/2016 - (Made some increasing)
BIO GROW - 2ml, ALG-A-MIC - 3ml, BIO BLOOM - 4ml, TOP MAX - 1ml.
WEEK 5 - 08/11/2016 - (Made more increasing)
BIO GROW - 2ml, ALG-A-MIC - 3ml, BIO BLOOM - 5ml, TOP MAX - 4ml(as table of BioBizz).

Thanks you all share your thoughts with me :)

"I'm using 4 x LED bulbs 26W each (2,450lm)".........You could use more light if that what you posted is correct..you have enough light to get as far as you have and I am impressed what you have grown with the lights you have, but it isn't nearly enough to promote vigorous growth/flowering.....sparse growth.....that being said...have you looked underneath the leaves for signs of pests?

Try flushing for a water cycle, may be nitrogen deficiency, leading to lockout, after flush hit em with half nutes and light water. Wait a day or two than wAter with half again. Watch your girlsg, then go full feed. This is similar to a problem I had with my mini plant I was just underfeeding by the tiniest bit lol. Im no expert btw

Doesn't look like anything to worry about really. A few spots on a few leaves won't make the slightest difference. Pretty rare to have very leaf on a plant looking perfect. What kind of strain is that though? Looks like a Mexican Sativa or something. Probably not going to get much from it. Doesn't look like something that would be worth cloning to me. You gotta get a good strain and then you gotta find a good pheno from it. Maybe you're a Sativa fan though, I don't know. Just kind of a skanky looking plant.

That is completely backwards. The lock out would lead to deficiency. There is almost too much N. Se how dark green it is?

You have a P deficiency probably due to a combo of lockout and ph problem. Flush with plain ph'ed water and let dry or water as normal with just plain water for a few watering's.

Generally start nutes at 1/4 to 1/3 strength to start out. Some plants are finicky about being fed and what. Looks quit green. Too much N. Not in N tox yet just an abundance of it.

Plain water for a bit will remedy these things.

They look a tad over watered to. Lift the pots to feel if they are light before watering.

Tall lanky sativa will look like that at 5 weeks of flowering, it looks good overall. Might take along time to flower, 14 weeks is not unusual. Measure it everyday if you can to see if it is still growing taller. Sometimes the stretch goes on for up to 7 weeks in soil, meaning a potential 16 weeks of flowering.
I agree that they will want a lot of light to finish well, but I'm not the one to talk about lighting.

How much water do you use each watering?
How large are your pots?
What brand soil?
Did you say you fertilized with every watering or do you water between fertilizing? How many times do you use just water between ferts.

Apologies, was simply stating what I had/remidied my problems with. My plants looked like that in the first weeks, added N and its looking better than ever. No arguments if my solution isnt right in this case

This.

I will also say if you feed every time mix weaker and water until 20-30% runoff to prevent salt buildup.

Thank you all for you're replies! ur aweosome! I need to water her tomorrow, so help will be much appreciate so here are more details:
- My pot size is 13 L.
- Watering each time with 4.5L tap water that rest 24h outside and mixed with nutes just before watering.
- In flowering stage I watered with nutes every time, not used plain water (only in veg for several times).
- I'm using mixed up soil with some nutes already, bought regular soil but in high quality for the market.

@vaporz yes my info about the light is correct,still don't have a good pro light for growing. Baiscally can use lights up to 100K lumens right?
I'll look tomorrow under the leaves.

@BobCajun It's 70% sativa 30% indica, strain from medical stuff I had and tried to grow. Already cloned btw :) I know that plant is not should be perfect and leaves will die on the way.

@whitebb2727 I do suspected a P deficiency, as I checked my runoff lately in the last few watering and found it's about ph 5.7-5.85 which is low.
Each watering I have about 30% runoff or more as I have 13L pot and I'm watering 4.5L each watering and I'm checking the weight and if the soil is dry before watering.
What you suggest, to water her with plain ph'ed water? I think it's better this way than flushing the system in that stage right?
If watering/flushing with plain water, what ph range you suggest according to the low run off?
Hope you can clarify this sentence for me again:
Generally start nutes at 1/4 to 1/3 strength to start out.

@Buba Blend Please see my details above, watering each time with nutes and 4.5L. Each watering after 3-4 days.
The stretched stopped a week ago, now she's not growing up anymore, stopped at 130cm for now.

@karma4life Amazing grow! very nice mate.

Thank you all, very appreciate your help.

After reading more members suggestions, Im more in agreeance with them and you that it probably is a pH/nutes type issue possibly, but can never tell whats on the underside of a leaf if it has been a while since a good inspection.

Just wanted to let you know im impressed with the plant provided the lighting you are using. I got a small hps light I bought a few months back for starting my first grow. Not knowing how it would turn out I didnt want to sink alot of money I dont have anyway into something I might fail at LOL....but it's a little 150w hps sun system.....can get it for $58 bucks give or take a few bucks by doing a search.....small and doesnt get to awful hot like bigger systems do but if stuff it in a closet or small area like that will require some ventilation cause it will make temps rise 5 or 6 degrees...just wanted to throw that out there to you in case down road looking for a small upgrade that is still small enough to be pretty stealthy...you could use that and use lights currently using for supplemental lighting or something...anyways bro good luck and keep updated on your grow

Its fine. Since you water with good run off I doubt it is salt build up. Its not a big issue. I think a few plain waterings will help it a lot. If it doesn't, no harm.

Definitely do some studying on watering soil. Most growers will water 2 or 3 times with just plain water between feedings. Might want to consider looking into the amount you water and how often. 4.5 liters when watering is a lot of water.
I think a lot of growers would agree you should water more frequently, using much smaller amounts than 4.5 liters (maybe 1.5 liters?) and you should definitely add some water only feedings between your fertilizer feedings.
Sounds like your allowing them to dry nicely between watering, that's good. If you try to water more frequently with less water the key is to still allow the soil to dry between watering.

Thank for your help.
Checked underneath leaves and I cant see something suspicious.
I saw today that soil is still moist, so I will not give her water today. Actually I watered her on last Friday on the 11th (I had a mistake in my first post which I mentioned twice on the 8th).
So this is day 4 without watering, seems she still not need watering even after 4 days period which normally today I had to water her, so maybe this is another clue?
I will listen to your advise and tomorrow I'll water with only plain water, 7 ph'ed to increase a little the soil ph and I'll update you again few days later.
I'll watch her progress and will take some pics for advises :)
btw, flowers seems to become fatter so I'm happy, and odor is fantastic. It's my first time to see this time lapse without knowing what to expect! haha

Later, if runoff ph will increase and plant will look better, than to continue with fertilizer feeding same ml/liter where I stopped or do I need to give her maybe 1/2 of ml qtty?

@vaporz Thanks man it's good to hear sometimes nice words haha ,about LED light, I saw prices are very high, maybe I'll do one by myself for next phase. Definitely I have to use much stronger light as I believe I will not get so much yields from this cutie.

no problem, I was re-examining the pic's you posted trying to see what medium you are growing in, in one pic I can make out the container but not very well, it seems like there is a bit of perlite in there but really hard to tell, depending on how much perlite you have in your container, you might want to add a little bit more to help increase the drainage...in alot of threads I see a ratio of 70/30 alot....that would be 70 soil and 30 perlite...somewhere in that range would work i think and you could get benefit of increased drainage and maybe a bit more space for roots to do their thing.

If you can get these issues under control, i would start off light or like you said 1/2 and see how that goes, if everything is resolved and looking good on the 1/2 strength nutes, bump it up just a bit next time you feed and monitor it close.....i think you will be set and back in business.

I used 100% soil from a 20kg bag, no perlite inside...
But next phase I'll do 70 30 as i saw many growers use this medium.
Just let her dry and watered her with plain water at ph 7 to increase ph of soil.
Hope to get in control and to continue feed her next week with 1/2 nutes.
Ill keep u updated for good and bad :)
Btw, just checking some LED bulbs that will fit my growing room. Do you guys think its a good choice for 1 plant?
4 bulbs of 36w for 1 growing i think are enogh:

Of course it's not for pros. But i do think it's much better from what i have today and its fit my growing room now.
