Hi ya'll.

I've have a Black Indica clone that was doing well before my efforts to eradicate some spider mite buildup I caught in the nick of time. I used organic methods first, then stupidly Acetamiprid: a mould/fungus/mite killer. I've laid off any such treatments for the meantime as I'm in the second week of flowering. a cold wash under the shower head with slight pressure every other day for the past week is keeping notes at bay somewhat.

This baby was doing great out in the direct sun until after a neem oil spray (than wash after 30 mins dark lights so as not to burn my leaves in the light). Then another thorough wash down. The next treatment after 2 days was more chemical. I used Acetamiprid with a toned down mix in water (precious uses experience burnt my leaves so half doses play it safer), followed by a quick wash. BUT having seen a Deutch Welle documentary of Acetamiprid use on fruits and vegs that led to cancerous side effects. I stopped using Acetamiprid after that altogether. Cold wash is a hassle but Plant really shines green and sprouts soon after and no Chens involved to alter my plants natural chemistry.

The leaves at the lowest part began to turn yellow/brown but started at the tips and slowly worked their way inward. Green would diminish completely after 1 week. (See 3rd leaf comparison pic).

Someone suggested nute burn from an NPK of 5-15-45 at half dose for a 5 gallon pot (2 litres per 1/2 tsp NPK). My last nute feed was a week ago. I gently use this every other watering for the flowering cycle. That particular person suggested to just flush and water lightly minus any mutes altogether. I did that too but the problem doesn't seem to be improving, but now getting worse. The yellow/browning that was originally at the bottom of the plant has now shifted gears into the middle/center of the plant. I can see the 3/4 top of my plant tips slowly starting to react the same way even from simple watering. I avoid overwatering and drowning. It does get hot outside more than usual. But the soil isn't drying out as quickly and I know my root system is intact and not getting any severe rootbound issues.

It can't be the mite treatments. My run off is approximately 6-7 pH. I have only ph strips to get an idea. The rest I log in a diary with nutes/Watering and bug issues, etc. the top/middle leaves didn't get burnt at all as I was careful in dosage and an after spray/wash once 30 I felt was enough to suffocate the mites and wash the leaves off before any burns took place from neem and garlic oil (garlic was to destroy most of the mite eggs).
it can't be rootbound so soon becos I can't see any root tips popping out the pots drain holes I drilled all around for better drainage.
I was also told it might be a magnesium deficiency. I got some Epsom in crystallised form (the kind from chemist/pharmaceuticals, not the rock form). I noticed a healthier green in them but since I saw the problem hadn't diminished, I've laid off the mag-sulphate feed and still this is happening.

My last resort was an N-def. but I've gave this baby a very mild feed from the 5-15-45NPK I have. I can't find any other nute variety in my region. This was the best option I had for a flowering nute feed. I've used dry cow manure as the original soil fert which has been doing fine the last 3 months. Only a punch in the entire 5-gal soil mix (4th month flowering, entering week 3 as of today) .

In order of uploads it should be:
1) a fuzzy pic iPhone couldn't focus on in dark outside.
2) Second pic is the middle of the plant. I noticed the mid section 4 days ago was speeding up that yello/brown effect from the lower section to now the middle/mid plant height.
3) The third pic of 3 leaves shows a degradation comparison I plucked off the plant to get into some good light to see clearly for ya'll.
4) the last pic should have come first this was when I first noticed the condition near the lower part of the plant only 2 weeks ago.


What's going on here guys? This is my second grow and I was doing so much better with the clone than I did with the mother. Up until now. Ever since flowering came about this has started to creep in the last 2 weeks.
Im stumped and need to resolve this asap.

Point to note. You might not see it but the new growth at the bottom part of the plant, and at the very topmost are still a good green and healthy. Apart that I'm kinda clueless. Pls ask if I've left any key information out.
Thanks!

Wait, so you do still have spider mites? What kind of nutrients are you using? How many gallons of water did you flush with when advised it may be a salt build up the first time? You said that is a mother plant; How long has she been in what type of soil? Yes I do recognize the deficiencies, and I have a hunch why but I think you are very proactive so I want more info before arming you with possible action :P
 
>> Wait, so you do still have spider mites?

Eggs perhaps. No sign of mites yet from third cold bath every other day routine.

>> What kind of nutrients are you using?

NPK 5-15-45. Not sure brand. Maybe Growmore. Also separately Magnesium sulphate (Epsom) only recently. Some German brand.
I've stopped both for last 2 baths (5 days)

>> How many gallons of water did you flush with when advised it may be a salt build up the first time?

5-gal. Same size as pot.

>> You said that is a mother plant; How long has she been in what type of soil?

This one is the clone. Mother had similar soil mix, minus perlite, which I was able to find for the clones duration from solo cup and directly to 5-gal. My 3-gal experience wasn't large enough for me doing just 1 plant initially. Now I have 4.
Soil mix is perlite/peat moss/soil-less mix, 1:2:4, and dry/dirt-like cow manure (1 fistful). Had no problem with soil except mushrooms when temps were around 18-21. That disappeared as temps rose mid-feb here to a more stable 23-25. Humidity at 40-65% range lately.

>> Yes I do recognize the deficiencies, and I have a hunch why but I think you are very proactive so I want more info before arming you with possible action :P

Whadya say?? Where am I going wrong?

Ok I was just afraid there was still salt build up which was pushing things out but I don't think so. I think you need trace elements and personally I love Botanicare Cal Mag Plus. Cal-Mag Plus contains: calcium, magnesium, iron, boron, zinc, manganese, molybdenum, copper, cobalt, iodine, beneficial vitamins, twenty essential amino acids and select botanical plant extracts.
http://www.botanicare.com/Cal-Mag-2-0-0-P48.aspx

There is a possibility I am wrong but the only other deficiency with this profile is also solved by Cal Mag Plus. Yes I do add cal mag 5ml or 10ml per gallon along with chemical nutrients such as those you are using. I think for you I'd do 5ml per gallon at first make sure the problem doesn't exasperate the problem.

P.S. I could be completely wrong let's see what others think

Can't find Cal Mag here. Anything organic I can put together myself?

There is ton's of stuff like Cal Mag Plus I bet your local hydro shop has a solution. Also I meant to mention I don't like your nutrients either. For veg I use somewhere in the 3 1 2 or 3 2 4 range, notice I didn't raise Nitrogen. Even diluted 5 15 45 would be 2.5 7.5 22.5, see how the ratios are off. That is more of an outdoor formula I think where Potassium washes out of the soil easily. See in bloom I like to be around 2 2 5 so even there it wouldn't be great in my research. I was thinking possibly a total solution for both that included nutrients + traces from your local hydro store would be best. Hydro stores have everything here in the USA not just hydro stuff so I bet it is the same there.

I've tried soiless mixes and I didn't like them so I could be missing important details in helping you. Also frankly I stopped using peat in both soil and coco, both of which I do like to grow in.
 
Unfortunately there aren't any grow shops here that supply what I'm looking for. I did come across someone a while back they swore by mixing some babyfeed in water to feed certain nutrients to their plants. Can plants metabolise baby food minerals ??

Today I saw the stress of this condition move on up to the top most part of the plant.
Really confused. I noticed that all the leaves have lost their "darker green vigor" and is turning more of a lime-green tinge.
Is this still in the lines of cal-mag or do I have a N-def on my hands as well?? =(

flowering week 3 was going so well until now. I can still save her but I'm helpless without Calmag. Maybe I should try something like a high calcium babyfeed as a last resort - help!

I noticed leaf tips curling up last 2 weeks. Could be heat stress added to all this. Sun readings at peak times is 90,000 Lux and 40-50,000 in the shade (readings at same time in day about 1pm) on average I read most plants only need an 80,000 average or perhaps 75,000 lux.

I gave it some rain water as a natural component rather than tap water. Saved some up over the last few rainfalls. I'm thinking of moving it into the shade somehow for at least a few days with just water hopefully I can find something I've missed apart all this.

I reread the part about using epsom so you only used it once? Because I think you probably need some every watering and I thought that is what you meant. I think that is where the problem lies actually because actually the Soiless mix if of quality should have micros. Also try not to over feed her this is still possibly a problem. If I were you I believe I'd just compost my own dirt from now on frankly growing in organic soil is the easiest way I have ever grown, just add water.

MeJuana. I'm gonna continue mag feed since it doesn't seem to harm anything in watering doses. I'll keep you guys posted here too.

Thanks s heal!! =D

If it is Potasium deficiency and you have trouble getting potash and the plant is in soil (i carnt be bothered reading it all again..lol) then some ash or coals from a fire will do. Just sprinkle on the surface and water in lightly.

????? Sure as HELL ain't P def with that stupidly high P&K bloom "poison" he's used!

The plant it's self looks to be pretty ok right now! And don't flush ever! If you have an overage - water it out with straight water pH'ed to 6.7 for soil.....for 7-10 days and then continue feeding....

What exactly CAN you get for feeding it?

You can soak eggshells in water and use that to help. Power or pulverize the eggshells and add that to the soil....

Lucky Luke, the coals were lit few hours ago. Just waiting for it to all die out. I'll give this a try and let you know asap!
Thanks a heap for your recommendation!

As of today here's what was happening after a nozzle bath for a mite prob I've had lately:

All that came off from nozzle pressure. Too many!

Yellowing continues. More updates after ash feed. *fingers crossed*

Cheers Dr.Who!! Egg shells are soaking in water.. I was told by another friend that a day or 2 is sufficient soak. However some have mentioned that it takes a month for egg shells to make my water soak more potent. Is that too long or should I crush/pulverise soak for 2-4 days?
