I have yellow leaves with brown around the edges and the veins are a light green.

My friend said they have lack of nitro but im not sure. Please help

I have a flood and drain with a 25 res. I flood every 8 hrs.
Nutrients are general hydro hard floramicro, florabloom and volcano guano.
Im using the lucas method along with cocoperl with smart pots.
i have had the clones for a week and they are about 7 inches tall.
Temp is around 70 and humidity is around 50
i have a 400w light about 9 inches away
My res is 6.2 ph nd 470 ppm
Soil is at 7ph and 170 ppm

I am not familiar with using coco and flood n drain, but they look over done.
They are way too young to get such high amounts of food.
I would think to try and flood them less often than 8 hours... maybe 12? They look too wet.
Good luck,
Trich

From the looks of your pictures, I think you are OK. I'm on my first clone attempt, and it seems the new leaves get green, but the older "cloned" leaves are dying off. Keep a close eye on them in case the new growth gets the same issues

Good luck with your grow!.
