HYDRO What is wrong with the leaves of the plant? Help me.

[LaVince]

I'm doing hydroponics.
{ The concentration of Ph is 4.8.
The air temperature is 25C.
The temperature of the water is 19C.
Humidity is 45%.
The above tree shape is only a sticker.
The growing box is made of styrofoam.
Put a plastic bag in the box and fill it with water.
Currently, nutrients use 10ml of FloraMicro, 10ml of FloraGro, and 10ml of FloraBloom for 2gallon water. }

The underlying leaf is curled.

And it's getting dry.

There are two plants, both of which show the same symptoms.

It's been 25 days since it sprouted. Is it slow to grow?
What's the problem? Help me.

Hi Vince,

pH range needs to be 5.5-6.5.

What do your roots look and smell like? Is there any light getting into your reservoir?
