I took a look at your journal (your plants look great overall btw. good job).
So here's your last feed?
- Tiger Bloom 2tsp per 2gal water (1tsp per gallon)
- Grow Big 2tsp per 2gal water (1tsp per gallon)
- Big Bloom 3tsp per 2gal water (1.5tsp per gallon)
Here's the feedchart:
The above are full strength amounts. Note, full strength assuming 0ppm starting water would give you 2.5ec or 1750ppm (700 scale) or 1250ppm (500 scale) for weeks 5-7.
Take a read through this:

I typically aim for 1.2ec nutrient solutions with autos. (600ppm on 500 scale; 840ppm on 700 scale). Note, the

feedchart uses the 700 scale but the 500 is more common. Better to go by EC to avoid ambiguity.
So to get 1.2ec you'd want to scale that feedchart for weeks 5-7 around 50%. So personally, I'd be aiming for the following:
- Tiger Bloom 0.5 tsp per gallon
- Grow Big: 1tsp per gallon
- Big Bloom: 1.5tsp per gallon
So basically dial your tiger bloom back. You want to maintain those ratios established by

to maintain proper NPK balance. Only adjust the dilution. You measure your nutrient solution with a TDS/ppm meter. It's also a good idea to measure your starting water. So if you're starting water is 0.2ec, aim for 1.4ec nutrient solutions. If your starting water is more than 0.4ec, you might want to treat/filter it.
If I were you, I'd give an extra plain watering or three in before your next feed.
And what medium are you using? And how are you checking pH. Is it accurate?
Good luck pal!
