Using FFOF .....
- It is already PH ( 6.3 - 6.6 ) using oyster shell to control.
- It runs a bit HOT for some strains ... And will throw leaf issues.
- You can use TAP water with it for normal watering .
- There is absolutely NO REASON to check runoff .
- TOO EASY TO ADD " WAY MORE " nutes than necessary ( by adding too many different products , in an already hot soil. )
- Sometimes needs CAL/MAG to keep uptake balanced.
- Needs more perlite - usually around 25/30%
You can cripple your autos by throwing the kitchen sink at it.
I see some canoeing ( leaves ) .... Keep air moving thru and over canopy.
Leaf fading during this early flower .... It is a heavier feeding plant.
( next feeding - try a split Veg nute / Bloom nute mix ) 50/50.
Then adjust as necessary. Some strains like more N than others.
Forget breeder harvest times ... You will do better if you let them run until done.
Not by what a breeder says. When you think its ready , give it another week.
