I’m running my first grow ever in a Rdwc system using an hlg650
My parameters are
85 degrees lights on
75-78 degrees lights off
RH 75% lights on - 60% lights off
Ppm 290 using current culture nutrients(following undercurrent feeding schedule) + Power Si(0.25ml gal)
Ph 5.7
Water temp 66-68
Light intensity 40-50%
i transplanted my seedlings on October 16 so almost 2 weeks since.
Roots started to appear 2-1 days ago and seems white and healthy.

2 plant seems to be doing okay because i used rapid rooter plugs the other 2 I had problems with yellowing leaves I thought it was maybe because i put the water level too high and it overfed the rock wool, so I went and removed the rock wool and replanted the bare seeds into the hydroton

Now it seems that 1 of the plants grow with yellowing spots and the other one had some kind of mutation and didn’t fully developed the whole leaf.
I would appreciate any help this is my first grow and I’m not sure if I’m doing it right.
