I am trying to figure out what is being used here, I really have no idea what peat blonde really is. It must be some form of a peat moss mixture though.

You also dont say if there any nutes in the soil. It is soil correct and not potting soil? At three weeks old, it may just be needing its first dose of nutrients.

Next time you transplant, add some perlite, it is very inexpensive.
Peace

thx VM , im not sure if its the correct soil. its called TERRA PROFESSIONAL PLUS+. there is a mix witch is just called TERRA PROFESSIONAL which has perlite BUT at the time of buying the only one available was TERRA PROFESSIONAL PLUS+. this was more expensive and was told it was better. the problem is i live in spain but my spanish isnt perfect, so understanding some of the labels can be bit difficult.the only difference i could notice was the water retention. from what i remember the TERRA PROFESSIONAL PLUS+ mix had a retention of about 7.0 (i think) and the TERRA PROFESSIONAL mix waqs about 5.0 (i think)

also therers no nutes being used just water, what would you advise for nutes, his got BIO BIZZ- rootboost,grow, bloom and top max. also supervit. thx for your help guys

oh yeah does perlite contain any nutes?

i just fount a link that explains the soil in english if this helps ya

im still a bit lost from what that says its perfect for indoor grows

im thinking maybe i should have started a thread! i hope you guys come through on this one. i told my friend to start feeding them rootboost and bio-grow on the lowest recommended dose. was that a good move?

Hey Keyunit,Yes start with alittle very little nutr.Perlite from MG has nutr in it.I learned that the hard way.I use schultz from wal-mart whitch you dont have over there.The differdsnce in that mix is one holds more water then the other.One drains faster.Put some perlite in that mix and you will have good draining mix.The yellowing is it needs some nitrogen.What is the run off PH?You may have to buffer the soil a little with hydrated lime,it all depends on the PH if it's high or low.You have good ferts start very lite and you will see them take off growing in a short time. Peace

thx toke, i was just reading the soil link, am i right in thinking that this soil is for the real pros like yourself and VM, by this i mean you can completely decide which nutes to give because theres none in the soil?
im not a pro so i think the other mix with perlite added would have been better for a beginner
also the pro whats better drainage 5.7(pro mix) or 7.1(pro plus mix)

needed a joint earlier sorry for my angry posts, and THANKYOU toke or whoever for making me a post

looks to me like it needs a feed of about 1/4 strength of a full dose of nitrogen like a fish fertalizer and next time i would definitely get the perilite mixture and then buy an extra bag of peralite and mix in some more with these plants you need alot of drainage.

Howdy Keyunit:

I think what you are interpreting as "water retention" is actually the PH of the soil.

For a soil grow you would want 6.3-7.0. As for the nutrients (fertilizer) it is always better to start off with NO nutes in the soil, and then add small amounts of nutrients as the plant can handle it.

Honestly, I would really recommend the ORGANIC GROWING MIX that Vidoe has listed. It is about as simple and easy a set-up as you can ask for (you don't feed to fertilizer) and it grows some aweseme plants! (just look at his pics)

thx for all your help guys, i went off today and bought a ph tester and some fish ferts. can someone tell me the perfect ph? the run off is at 6.6 (toke) i also checked the bottled water im feeding with it was 6.4, did i really need a ph tester?

Yes, that will come in very handy. (the ph meter) I am trying to find one here in this burb and having an awful time. Good luck. Oh and for soil it is 6.8 what you are aiming for.

thx j-angel, am i right in thinking that you check the run off after a feed with nutes?

Check your water and check again after adding nutes to it and correct. also check your runnoff that will give you an idea if your soil is out of wack too. Someone that knows more than I do should chime in here.

Good luck. I will be watching !
