Well with no other info looks like nitrogen and or sulfur. Possible just lack of light.

Balcony Auto Gelato with Yellow and Brown Leaves
I'm growing this auto gelato in a balcony safe from rain fall and harsh wind, it's the 25th day and the bottom leaves and cotyledon are turning yellow and with some brown traces. I started to use minimum amount of "all in one" fert. Do you think it is overfertilization issue?

Anybody got any idea with what's going on with these 2? The 2 larger plants are showing the signs of some stress on the fan leaves. Oddly enough the runt of the 3 is not showing these signs. Has anyone seen this before or can help me identify it?

Yellowing and lightening of leaves
My back-left plant started to slightly yellow on me from the bottom up. Front-left is also lighter than the rest. Is this a feeding issue? Do they need more nitrogen or did I overwater them? Appreciate your answers :)
