Well ive had this prob since i got these WW of my mate there from seed and were over 1mth old wen i got them, its my 3rd gro and never had this,well its my 1st gro using a ec meter which is a blue lab type and also have blue lab ph truncheon, im feeding them since i got them on an ec of 1.4 , and my back ground ec is 0.2,,,, ph 6.0 and water heated and bubbled to 22c and hand fed ? well any help or suggestions please , and ta in advance,,,Oss.ps also some drooping ?

heres some more pics and can somebody tell me wat ec i shud have for these as its my 1st time doing ec, and there WWidow, atb , Oss.

Hi OSS. Are those in compost? What type is it, and how long have they been in those pots? They look to me like they are gasping for a repot. If it is compost, you shouldn't pH the water, just give it from the tap, and the EC meter won't tell you anything useful.

Dont know the answer to your question, but like the other guy said, you dont need a ph meter for compost grows, or an ec. Follow the measurements on your nutrient bottles, normal 1-5ml per litre. Youll have to just exsperiment with what mixture you will need at first, but when you get nice green leafs again youll know your in the right direction.

Dont think youve wasted your money on the PH and EC meters though, just means you need to have a go at Hydro

Looks like the start of MG defficency.

Thanks Squirrel , Troubledmind, and weedwhacker, well im in coco and were repotted 6 days prev in to 7.5 ltr pots ? any help greatly appreciated , Oss.

Hi OSS. If they are in coco ignore everything I said in my last post, coco is a hydro medium as it contains no nutes. I agree with Weedwhacker that it looks rather like early Mg def, but I'm not sure, and Mg def is rare in hydro. The pots look rather small in some of the photos, especially pic 3, but 7.5 litres should be fine.

I'm not a hydro expert at all, but I would guess that you could increase the EC a bit. Best of luck with it.

What is the Ph of the runoff when you feed? Is it climbing? If it climbs up a few points you can try lowering your Ph when you feed - I like to feed them at 5.8ph during vegging and then start raising the pH to around 6. in the 2nd week of flowering onwards. (Coco ph range is 5.6 -6.5)

The drooping, curling down leaves looks like it could be overwatered or a Ph that is a little high - check it as you now have a meters you say.

edited to add: they look very good and healthy though =-most of them in the pictures.

thanks Culo and Squirrell, well there fine now and il post pics shortly in my diary,atb,,Oss.
