Some of the new growth started showing the dead tips yesterday, today it has spread to a couple of the older leaves and the new leaves in the middle look deformed with some of them so curved that the tip of the leaf almost touches it's own base.

 

Just recovered from spider mites, haven't seen any for a week now and stopped treatment for them yesterday.

 

From what I have read, nute burn seems most likely and the soil is an unknown quantity as when the seed popped I just grabbed a pot with soil from the yard to chuck it in, I know better for next time and will be well prepared for round two, but want to get this one humming as best as I can. It's had some very diluted seasol, and there might be some slow release junk already added to the soil.

 

I'll grab some testing gear to get PH levels if needed.

Yes I  have had this problem feeding my plants the schedule that the company gave me which was way too much for the plants. Give your plant half strength that the nutrient schedule says!

[bu11dog]

Thanks for that, glad it looks like it to you too.

 

It's only had less than 1/4 strength seasol twice, but there are those little coloured balls already in the soil which I think is some slow release fertilizer, it's started to grow a lot faster in the last week and I guess it's picking up some of that slow release stuff. The tips looked a little worse this morning, but there is plenty of new healthy growth coming out as well.

 

Should I leave it in that soil and hope it comes good?

 

Anything I can add to the soil to counteract or limit the effect of the slow release ferts?

Are you able to perhaps take us a picture of the whole plant without the LED lighting on? Personally I'd be trying to repot it if its not too big yet to try to get away from the soil. For a new grower soil is a bitch to use, especially with so many other unknown factors like how strong those nutes in the soil are, how long they will last for, the ph (water, soil and runoff) etc etc

 

Also, I'd be keen to find out more info on your light if you dont mind? Just curious as to how someone ended up with a 700W+ LED light but no coco or nutes?

 

 

Oh btw, seasol generally wont adjust your EC rating much so probably isn't the cause of any burn issues, think of it almost as the poor mans Rhizotonic (Nutrient additive, not a nutrient in itself)

I'll grab some pics minus the LEDs tonight.

 

The lights are 2 of the 320w here http://www.eshinesun.com/growsun/growsun-series.html and 1 older unit that claims 165w, not sure on it's actual draw.

 

I have other nutes, but haven't started using them yet, it's just 1 plant for my first run through with an eye to a bigger and better grow on my next attempt.

[bu11dog]

Finally managed to grab some decent pics minus the LED, it doesn't look to be getting any worse in the last 2 days.

 

 

I've since found out what was added to the soil as well, "Scotts Osmocote  plus trace elements, for vegetable tomato and herb gardens" - a handful of it about a year ago.

 

New growth in the undercarriage looks good, no dead tips or unusual curling.

 

 

It's been it that pot since the seed first popped, I have another pot with new soil ready to go if I need to transplant.

 

She is currently a month old and sits 15cm above the soil at the tip, checked the temps last night/early this morning and it's dropping below 10'c out there, I'm guessing I should try to sort that out as well?

 

PH of the soil is 6.4 and the runoff is 6.9, my tap water is 7.

Cheers for the non LED pics, a pic of the whole plant would still be good.

 

Have you just dug up soil from your garden?

 

There are too many variables to really tell what the problem is. It could be that there aren't enough or the right ratio of nutrients in the soil, it could even be damage from however you treated the spidermites. It could be something else.

 

I would transplant into a more appropriate medium, give it some time to recover from the spidermite attack and treatment and go from there. 50/50 Searles premium potting mix and cow or horse manure has worked well for me if you don't want to go hydro.

 

Good luck.

Thanks, I took your advice and transplanted it into some better soil yesterday, just wait and see now I guess.

 

It wasn't soil dug up from the garden, but with all the crap in it I can see why it looked like it, just a pot that had been sitting in a semi-open area near a wattle tree for a year or so. 

 

A couple more pics from today

Looks bad, get your medium sorted out son.

 

What sort of LEDs you got?

[bu11dog]

Yeah, I think the medium had a lot to do with the dramas, she's going great now - I'll be updating my grow diary soon and I'll throw some more pics up here too.

 

It took a week or so in the new soil to recover, then I hit it too hard with the nutes and had to flush - I'm getting my sh!t sorted out in that regard and she's looking a lot healthier today.

 

I have 2 of the 320w versions of these - http://www.eshinesun.com/growsun/growsun-series.html and one dodgy old fleabay unit that was advertised as 165w.
