hi

going to be starting off my white widows and russian rocket fuel (autos) in a couple of days

just wondering if anyone knows of a decent soil. im going to start them off in rockwool.

Have a look here. http://www.uk420.com/boards/index.php?showtopic=172589

I was looking myself recently as i want to try organic instead of the coco.

i use westlands advanced plus and never had a problem, used b&q multi purpose first time and plants seemed burnt on the leaves from early on

just looked at my local garden centre and all i can find is Westland West+ Multi-Purpose Compost 60L

is this one ok?

I only use organic (biobizz) nice and easy no need to feed about 2 weeks into flower.

edit: will differ with feed with lowryders i think.

We are big fans of John Innes No3 for the final potting soil, we use John Innes SEED to start then No1 then No3 to finish off with.
At the moment me mate has been experimenting with various mixes but secretly deep down I know he will return to the John Innes range once he's finished with his present crop.
Its a bit on the sandy side but top dressing every now and then really does help and give a sly little boost to growth.

I would normaly use wests mp but i bought a 60l the other day and i seems to contains an unreasonably large amount of uncomposted pulped wood, not like the stuff i had last at all. Decided not to take a chance on it and bought some jab mp with syncro boost from q&b, looks much better.

I've found the John Aurthur Bowers + JI from Q&B very good,I mix 20% perlite and 10% vermiculite with it for a nice spongy airy mix.Click to view attachment

Amnesia thats my preferd compost at the mo
thers no need to add anything to it, all your doing is diluting the compost with inert material
removing food

I found it holds the water for too long without the extras,i only water mine every 4 days as it is at the moment.

That is due to having a relatively small plant in a very big pot Amnesia, the root system is less dense so uses less water.

i grow in 50x50 eco-grow/multi purpose. eco-grow off the web & multi from wickes.
plants growing great this year.

I agree JI3 makes big buds

Heavy though - hard work lugging it upto the loft

Just had decent results with Westlands MP+JI

Present batch in Westlands hanging basket and container compost - looking good

Pardon me if this is a sily question:

How can you tell that the nutes in your soil have been used my your plants & that its time for manual feeding?

Usually they start going yellow at the bottom, you'll notice the big fans paling, this means they are hungry for nitrogen.

But isnt nitrogen deficiency normal during flowering. Im planning on using BioBizz all mix which has a higher concentration of nutes in it but if the fan leaves begin yellowing how woul dI know that its time to feed or if its just running through the course of the flowering process?

ive used west+ advanced and biobizz all mix and had pretty much the same results from both

both were a very nice medium to use

Of course, lower leaves yellowing and falling off is also a natural part of the plant´s life cycle. As the plant grows the lower leaves get starved of light.

Some people think it is better to starve the plant near the end of flowering which will result in lots of yellow leaves at the end.
Others think it is better to keep the plant green and healthy and pumping out the bud and resin full force to the end, and feed accordingly. Many organicish soil growers on UK420 are in this camp and follow the feeding advice of OT1.

A plant that is yellowing is spending energy on moving nutes around the plant that it could be better spent on building bud and resin.

e2a - As Cantharis says leaves that are not getting any light will yellow and wither too. This is not necessarily a sign of hunger just of a lack of light penetration, and the plant deciding that that leave is not doing it any good....

Both groups would see yellow leaves any earlier than 2-3 weeks before expected harvest as a sign the plant wants feeding.

As a rule of thumb if you are potting up regularly, there should be enough nutes in any decent compost to last 2-3 weeks after the final pot-up. If you are not sure if thet need feeding at that point start with very low doses of nutes and see how the plants react over a week or so, before deciding to up the dose, keep it as it is, or not feed at all for another week or two. Do some research on the feeding requirements of your strain as well.

Youve explained it perfectly thanks mate.

To add a little, I should mention that I pick up a handful of dried and yellowing leaves every morning.
