I'm having issues with this plant. I use PHd water at 6.5. I took a soil sample earlier today and mixed it with water, let it sit and measured PH at 6.8. The new growth is yellow all on the top of the canopy. Lower growth seems Ok. They are in a 2x4 tent under 400w timber lights. The temps range from 74-79 during the day and 71-68 at night they're in week 2 of flower and I'm starting to get concerned about this plant. I thought it was light burn at first and have been researching like crazy. Any help is appreciated
