I've got the same problem except not as bad as yours...yet. Look at the "Yellow spots and turning brown" post for pics. I was told it was a nitrogen deficiency but that it could also be a pH problem. I had this on one plant last grow and the epsom foliar feed stopped it in it's tracks. Not this time though and I've done everything exactly the same EXCEPT...first grow I gave them fert 12 days into growth plus some blood meal sprinkled on the surface. TOTALLY AGAINST WHAT EVERYONE SAYS TO DO!! And those plants were waaayyyy further along and healthier than these. What else can a person think but that not feeding fast growing plants isn't the right thing to do. They need food. I know that ruffles feathers, but prove to me that it's wrong based on what I'm seeing here. Plus I have way more light!

Here's pics of the first grow with lots of food and the second going by what everyone says...DON'T FEED THEM WHEN THEY'RE SO YOUNG!!!

First pic is of the second grow. No fert till today the 22 day. In a 3 gallon container. Everything done according to what so many people suggest.

Second pic is of the two I planted in the same container for my first grow in a 2 gallon container. Yes there's two of them in there but you can see that they're waaay taller and healthier. All I heard was that they were going to die an early death big time and be root bound to no end. Total BS. I wish I had four plants like these right now!!

Now where's my blood meal and Miracle Grow!! I combined these to grow the first which again is a total no no. Go figure.
Marc Benson Reviewed by Marc Benson on . Bottom Leaves Sick, Please Help, Expert Advice Please Please help with my plants, they have gotten sick on me about 5 days ago. The leaves are turning brown from the bottom up, 2 of my plants have lost the first and second set of leaves (from the bottom up). I did some research and thought I was low on P, so I gave them some epson salt and a little bone meal to bump the P. This is the only nuts I have given the plants for they are only 18 days old. Here are some specifics: Soil: 1/2 Scotts Potting Soil .08 .12.08 Nut Levels, 1/4 Perlite, Rating: 5
