Thoughts on compost tea?
First time making compost tea, if anyone can think of anything to build on, would appreciate some knowledge. Already have a 4-4-4 mixed in to the coco coir, so I’m making the tea out of 🍅 fertilizer for calcium and molasses for sugar.

I've been feeding 3 times/day at an EC = 1300 and PH = 6.2. Runoff this morning was ~700 on average. The plants appear to be happy but I'm worried that I'm underfeeding them and its slowing down growth. Should I increase EC? Should I start feeding more often?

Salt nutrients
Hi! Made an excel based on https://www.omnicalculator.com/biology/water-soluble-fertilizer to make a suitable recipe for veg. I believe the desired NPK ratios are around 313. I think I made an ok recipe, although its a bit high on Calcium. Think this will work? Thx!

Composted soil and pH
I read that using composted soil you don't need to stress about pH too much. My water tank gives water at 7.7. Run-off is fairly similar. Should i be trying to adjust this down a little before watering?
