All newborn leaves are too much yellow. Do you have any idea what problem could be? 7-10 days ago turned to 12/12 for bloom phase. I think its light burn, BUT even lower newborn leaves are yellow.
Your ph is out check your runoff. Your plant could be stressed. Also looks like you have an iron deficiency. If it was light burn your lower new growth wouldn't be yellow also.
Early stage magnesium defficiency. Iron defficiency can also cause new growth to yellow. You need to find out if it is defficiency or caused by lockout of either incorrect ph or to high ec. If both these are proper then it would be defficiency. Cheers
