Problems with my indoor plants

[Rayba]

Hello everyone.

I have noticed that 2 of my plants are growing slower than the others. The plants were planted on the same day (September 17) .
These are my plants:

Also the leaves of the smaller plants are not growing much.
I guess that slow growth is because the two smaller ones are in different soil.

What could I do to boost the growth of my plants? Or is the behavior normal?

PD: This is my environment:

It could be the different soil, it could be watering ( or the way the soil holds water. What soil(s) are you using? At this point, I would be careful fertilizing, if you do, the word “weakly” leaps to mind. It’s easy to burn seedlings.

What does "weakly" mean? Am I over-fertilizing or under-fertilizing?

It means don't feed the plant with a full dose. 1/4 to 1/2 dose is better for young plants.

It isn't normal. The different soil is probably the problem. My guess is the plants aren't getting what they need from their roots. That would be either water or nutrients, or both. I think I'd mix a water and nutrient solution. Then I'd water small amounts of it in close to the plant because the roots probably haven't grown much.

what’s your watering method? how much how often

Notice the perlite in the soil of the bigger plants? The smallest plants have no perlite in the soil, if you want consistency stop using different soil in the future.

The two small plants probably could be transplanted into better soil. That could work.

Probably soil and watering.but allsoo somethimes you just get retarded plants that dont grow
