Mix in some bone meal or sulfur phosphate.

Lemon juice and water should help too

lemons work for 24h then they disolve and make the ph as before. 7 is not that bad for soil. are you seing ph issues*?

No I'm the only thog I'm seeing is yellow tips abit that could be from to much light from flowering growth spurt so it might have been to close when they were growing
But was also just wondering incase I do see ph issues
