Yellow and curling upward

deadbolt742 · #1 (**permalink**) 11-03-2008, 08:26 PM

Hi not quite sure if its a problem, but just want to make sure since one of my seeds sprouted yellow and all the rest are a darker green. Also it seems that my leaves are curling upward and also I noticed that the ends of the leaf are sorta dark like blackish almost.

Growing in soil which says it has hypnum peat, forest products or compost, sand, perlite and aged pine bark. Don't know the pH and not using any ferts. Oh yeah also im using bottled water to water the plants but I am not watering to often since I really do not want to overwater the plants.

Curling upward

Another one curling upward

Yellow and not as dark for some reason

If you can see the tips are almost blackish

Leaves curling up generally means a Mg deficiency. Mg is locked out by ph that is off (you should get a ph tester) or by too much calcium.

It's kind of hard to tell at this stage though since they are so small and I wouldn't expect a deficiency to be hitting them yet.

Keep us updated.

Well im going to be ordering a ph tester online soon so hopefully it comes and I still have time before this becomes a problem.
Also I forgot to mention on the yellowish plant the inside of the bigger leaves are turning a reddish brown.
