root water temp 67f
good air flow in water with 2 airstones
ec .6
light at 300ppfd
ph 5.8-6.2
My athena nutrients are 3 years old, I do 1 big plant a year and on 3rd plant, but athena said good for 5 beings synthetic.

My first thought is it might be light burn. 300 PPFD should be okay, so I'm wondering if the foil has a multiplier effect. I've never used foil, so that's only a guess.

Hey what Athena product and are you using a feed chart for cannabis from Athena. There are several listed. Wanting to know if it has an epsom salt mix like jacks or has plenty of magnesium.

I would lean to Magnesium. Usually the plant with use it all up on new growth so the lower foliage starts getting less and less.

When you get a chance can you lift her up and get a picture of the root ball? That will give me a better idea on what's going on.
