My friend is 1 week in veg from cutting started nutes 2 days ago. There is 6 under a 600w hps about 18inc away in distance from them. They are in canna terra soil mix. Thers now a yellow tint coming across the leaf and tiny yellow spots on a few random leaves on each 1 also some of the very tips on the blades are slightly yellow. It seems to be starting from bottom and traveling up. Pics are not great but I'm hoping u can see how it is discoloring any help is greatly appreciated. Thank you!
Looks like mild nitrogen def to me but if you just started nutes 2 days ago hopefully that'll take care of it. What's your ph?
Thank you. I will keep checking over next few days and hope things change. Will leafs that are affected get green color back ? Or will it just stop the rest from going the same.
