something is destroying my WW! HELP!

[Guest]

I have a white widow that has been flowering for 4 weeks. A week after I had transplanted her into 10l pot, her lowest fan leaves turned into like this:

and like this:



I know that I didn't hurt her roots. In transplanting I used soil from my last grow, it was flushed for 2 weeks then.

I have flushed her twice but nothing happens, step by step all fan leaves turn into like this. fan leaves started "rotting" from their leaf tips.
I thought it was phosporus deficency and gave her NPK 8-8-6. after that most of the fan leaves were like this:

please advise me what to do next, I dont want to lose this beauty!!!

edit: I used pure tap water for flushing and for watering, so there can't be a calcium deficiency!

I really need your help


thanks

adjust ph in water to around 6.0 and flush once soil dries out a little more with about two gallons of ph adjusted water. PH and wrong fertilization methods the precursors to all deficiencys.

yeah i would say its from ph .. if not that then add a tiny bit of mag, but im going to say make sure your water is ph'd

 

[Guest]

thanks for responses!

I use the same tap water to water my other plant, ms Bubblegum, she is allright. so the PH of this water must be ok. instead of old used soil I bought new soil for her. problem must be in that reused soil I think.

so I'll give her a bit of magnesium. I also try to foliar feed her with 8-8-6 fert.

please suggest something!

thanks

i'ed assume that the reused soil is deplted of it nutes, but then again my plant are crappy,what the hell do i know

That looks like like what my plants start doing when my ph starts getting to high. Tap water usually has a PH of about 7-8.5 and thats high. If your growing in soil, that in itself is a buffer. Any PH problems wouldn't show up for a little while. I would check the PH of the runoff. I would almost bet anything that it's due to high PH

 

[MynameStitch]

have you tested your soil for ph? test strips? you test the run off of water after you water your plants, you collect the water from the bottom of the pan

how much ferts are you using and how often? and what kind?

also you say you flushed, how much water did you use
how big are your plants and how tall are the plants?

another thing, why are you foliar feeding with 8-8-6 when your plants should be using bloom ferts not vegging ferts

right now your plants have less of the nutes they need and more of whatr they dont need

they need less nitrogen and more P K
so it should be like 2-5-5 or something like that

what soil mixture are you using?

thats my girl few days ago


I know how to measure PH but I can't get quality stripes, so I don't know PH at the moment. jep my tap water might have a high PH but I use now ph 7 water.
after these problems I haven't used any ferts. I used about 8l (2gal) tap water to flush, it made things worst to be honest. so my tap water must be shit.

I read once that most beginners use too much p for flowering and n is also needed, so I decided to be not an ordinary beginner and used 8-8-6. So I get some 2-5-5 or equal organic fert. my soil is ordinary black soil from Biolan without any perlite or vermiculite.

really thaks to you MynameStitch

will see what happens

Hi Ahamaraka,
your problem has definetely occured because you re-used your old soil mix. Now don't get me wrong, I recycle my soil all the time but you have to have a top quality organic soil to start with or it will degrade over time. Most soils turn strongly acidic or compact up after one grow already.

But, even if you have got the best soil mix you can have, it needs to be recycled before it can be re-used.
To recycle, flush thouroughly first, then add about 10% Wormcastings, maybe a bit of perlite and about 5% of highly concentrated fertilizer to get the nute levels back to what they were. It is very important to remove as many old roots as you possibly can too.

Now your problem is most definetely either due to a wrong ph or from a nute burn.
Because you are re-using your soil without having recycled it, I am suspecting your mix has turned highly acidic.

In case you can't find a concentrated fert for recycling soil, you can make your own by adding these ingreadients:

- 2l bone meal
- 1l blood meal
- 1l Dolomite Lime
- 1l Kelp meal
- 1 cup of epsom salts
- 1 teaspoon fritted trace elements

Mix and let it sit for 2 weeks, check ph(runoff when watering ph 7 water)

That would give you roughly 5l of concentrated fert which is what I add to about 100liters of my old soil.

So check ph for now as that is your most likely culprit and gl.
