Growing 2 Plants - One growing slowly


One of the two plants I’m growing is suffering and not growing as fast as it’s sibling. I’ve given them both the same treatment, light, nutrients, water, tested the soil.

The top leaves have a weird discoloration on it, could it be a disease?

Any suggestions?

Here is the other plant for comparison. We are at roughly Day 18 since beginning Germination.


They both look healthy, many times the runt will eventually surpass the early growers.


Look some grow abit slower give it time to grow

Still seem to have issues with the left one. Any suggestions on improving the growth. I’ve been giving them nutrients, checking the soil ph. Only difference I can think of is the one on the left has a top layer of miracle grow potting soil. The left has normal soil. Anything I can do to correct it?
