Problems with snow whites,have pics , about four weeks old, any Ideas?

These plants are about four weeks old and started showing problems
a week ago, not sure if its lack of N or magnesium, might try bumping the nutes
up to full veg, I dunno, any ideas?

kind of looks like nitrogen deficiant usualy lower leaves will yellow when nitro is low

Has to be the nutes

Yep,might go full strength tomorrow, don't want to burn the shit outa them though

Gave them full strength veg nutes, they're looking alot better, must have been lack of Nitrogen

Sweet. Great job.

Yup, gonna keep a eye on them though

and, yup, they are looking 100% better
