Leaf Discoloration

[rudeboy1876]

Hey guys I’m growing in the same soil for both plants. One seeding is green and the other is yellow. When the first set of leaves came out it was yellow, now its green and the first set of real leaves are out n now are yellow. I know it can not be a nitrogen problem because the leaves are growing healthy. What you guys things?

what kind of lights are u using, did u add any nutes? gimme a brief description of the situation they have been in

It's too small to see if it's iron, suphur or copper deficiency, but it's definitly one of these three.

Buy some molasses and add 1-2tbs/gal every watering. This will fix which ever one it is. Don't try fixing this with nutes that contain microelements, because you may burn your seedling.

If its a deficiency of some kind, why my other seedling isnt yellow? They were both started in the same soil type with no nutes. BTW thanks for a response guys.

Also they are under three 23w CFL in scotts premium potting soil and MG perlite. Its just under 77F

This happens loads of times. Even with clones or same strain seeds. One of the seedlings just happens to have a larger deposit of iron/copper/sulphur (it doesn't have to be much, since it's a microelement) while the other doesn't.

PS: it's probably iron def, it's the most common one.
