Leaf colour?

hi, why are my leaves not dark green my plants are 4-5 days old and have there 3 set of leaves on but the leaves are light greeny yellowish please help

you giving it any nutes? wats the temp of your grow space? could be heat issue or nute burn....

Whats your plants environment like?

Temps are low in room
No nutes yet
400 watt hps far enough away so it doesnt burn the back of my hand
dwc setup----water temps are low with few airstones
using clay pebbles. watering plants aswell once a day untill roots have fully established
fan to circulate air around

Do you think the they are lacking some nutrients??

Bump, anyone there???

I would add a 1/4 strength nutrient solution.also i water my plants at least 3 times a day depending on the grow medium.Are you using rockwool cubes or just the hydroton?Keep your water between 18-25deg celsius 22deg is optimumkeep your pH between 5.5-6.5 5.8 is optimum

hydro is sooo god damd hard. id love to try it but all i forsee is problems...

i did this for my first grow last time and it went really well, im using root riot cubes and the clay pebbles. i will check the ph and start the nutes tom il keep updating
