What brand / type of soil are you using? Any perlite or other lighteners / conditioners?

And by the way, if that pot has a built-in saucer on the bottom, rip it off. Just set the pot on a clean, dry saucer or small plate. You don't want to have standing water in the bottom of the pot, or in that saucer. That's why you also need an inch or so marble-sized gravel in the bottom of your pot.

There's lotsa FAQ's around here but not so many devoted to "just" soil. :wtf: Read what you can find, and I'll help ya if I can.

If you can let the plant go longer than 48 hours, let her dry some more. When mj starts getting thirsty, she'll pull water from the bottom leaves first, and they'll start wilting. It's not good to let the plant go this far real often, (it does stress the plant a bit and change the chemical environment) but if you notice the bottom-most leaves going limp while everything else looks good, that's when you NEED to water. The plant does give us that warning. It won't just turn crispy and die suddenly--you've got a 12-24 hour window (again, huge variables) to help the plant rehydrate those bottom leaves. ("Water pressure" inside the plant cells is what gives the plant turgidity; when she starts to dry she gets limp.)

I'll try to find an example pic somewhere.

Your yellowed growth is gonna stay that way. So when you're checking your girl for signs of improvement check out the new growth instead. But leave the old ugly growth on the plant. She'll drop it when she's done using what she wants from it.
