Brown Edges and Spots Late Flowering

[Stimn11]

Problem: leaf edges turning brown with spots between the veins. Yellowing veins. Leaves clawing downward. Brittle leaves that snap when bent.

Medium/grow method: fox farm ocean forest

Feed and supplements used: Blue Planet nutrients organic every other watering usually water every other day. I used mammoth p 2 times during flowering and gave 1 scoop of pk booster after flush thinking it was a k deficiency
Week 7 feeding schedule
7ml grow 4-0-1
7ml micro
10ml bloom 0-4-4
3ml vitablue 2-1-4
4ml liquid blue 2-4-10
1/4tsp easyweed 1-2-18

water source: Tap water ph 6.5

Strain/age: Gorilla Cookies around week 7 or 8

light used: Spider Farmer SF-2000 200W dimmed to 80% around 14" above canopy

Plant started with browned edges of the leaves and spots between the veins, I did a flush and after a couple days started with the nutrients again but the problem started to get worse

What’s the ppm tap u start with ? Just curious could be overwatering are u letting them dry back enuff? Those are pretty mature and prolly don’t drink that fast ? Not familiar with your nute line I’ll have to look it up could also be a calmag issue mayb too much ?

I only water when the soil is dry sometimes every 3rd day sometimes every other. The ppm is 130 of the Tap water
