jock horror, always the same problem, i need some help..

i ll transplant her later at new brand soil and i ll see how it ll go.. with a friend of mine we have exactly the same setup and do the same things and he hasnt those problems.. he got also the same brand, but not from the same bag.. i hope she ll live..

just re-read urs back dude & new soil sounds like good idea - i hope it works & maybe try some other seeds or if u could get cuttings off ur mate would be cool too. Hope it goes smooth finally anyway man!

he's growing with led's. From my experience I don't ever get burns from LED's and they are right up against them. Granted, not from seedlings but still... I think its a problem with your soil. I checked a google search with bizzsoil and others have had your problem also. But again, many others haven't had any probs at all. My advice, is flush with water, only water, and lightly and if this crop fails, pick up another bag. Keep what you have for after your first transplant. But from your pics, they look over nuted and if you're not adding anything its gotta be the soil. Its really not that uncommon. I almost picked up a more nuted bag of soil that would have burned my clones just last month. My hydroponic and product worker helped me get the right bag. Good Luck Buddy!

thanks a lot people! i transplanted them and it continues.. it s geting new leaves, but all the other are the same and worse.. yellow around the edges at the start and then brown and dead.. i ve put my last 2 seeds and today they have sprouted.. the 1 is at biobizz again lightmix (but from another bag) and the other at flushed biobizz lightmix.. we ll see how they ll do.. also i took away my led at around 30 inches just in case it is that the problem. i have a small cabinet around 19,5 inches width, 14.5 inches lenght and 71 inches tall. maybe it is too much light for that small place.. from the top till down all the leaves are yellow around edges.

MAGNESIUM DEFICIENCY! I'm growing Jock with Light Mix soil and pH 6.4 water just like you. I also introduced them to a 600w HPS after they were about a week old so you should be having no problems with your lights. I got the same problem and after reading up found that light mix has no mag and not enough cal. Picked up some magne-cal+ from my local hydro and it sorted the plants out in a couple of days. Hope this isn't too late to help!

6.3 is running hot, try 6.6 and dont over-water it. ..it seems strange your pH in is at 6.5 and your pH out is at 6.3 and your potting medium is so small.. something in there is going super acid, thats your problem. maybe the powdered crap did it?

I use pure coconut hust (coir) for seedlings and clones, the seedlings need almost nothing but water and warmth to sprout.
