Hi Folks (edited to include Soil details)-
New grower here... I need help diagnosing a deficiency.

My gut says that this is Phosphorus + CalMag issue.... but I'm a newb.

Details:
She-Hulk is her name
Bruce Banner Autoflower
Week 2 of Flower
Soil (Fox Farm: Ocean Forest) with a mild nutrient schedule of Fox Farm Big Bloom (Veg) + Tiger Bloom (Bloom). I have never gone full strength though. Last week was 1/8 Veg + 1/4 Bloom.
Did accidentally have water that was too high on the Ph scale given to her about a week ago... OOPS!

Help!

Here are some tools to help figure it out. Try the Cal-mag on a plant and see if it helps. I would have to ask about feed schedule and watering practices too. Salts build up. Then they start messing with feed. Have to wash them out while watching for overwatering. The clawing and burnt tips are saying too much something.

And to make it more confusing you can be simultaneously having excess of something and a deficiency in something else. My gut says he is actually deficient in phosphorous but likely more than that considering the light feed and 4 weeks of veg likely exhausted the pre charge I’m the ff.
