A question from a fellow grower:
I’m a first time grower and i’m facing some issues with my plants. I have 2 plants (critical+) in a 2.6inchx2.6incx5.2inch grow tent with a 250w hps light and both of the plants are growing in soil.
One of my plants is much smaller than the other (they were both germinated and put into soil in the same time), the colour is lighter and has some kind of necrosis in some of the leafs.
The other is much bigger and bushier but darker in colour and also has some of the necrosis one some of the leafs.
But the bigger one, now is also showing some signs of “claws” in the leafs.
I already flushed the smallest one because oh the PH values that were high (in the beginning) but now, both of them, when i water them, give me a runoff water oh 6.4, 6.5.
I really don’t know what is causing the necrosis and some leaf deformities in the smallest plant and the dark color in the biggest.
