Your Ec at 1.0 may be a tad high for an autoflower. Start of at about 0.6 and increase by 0.2 each week. You will find an Ec above 1.2 can cause a bit of stress to autos for some reason. Once I push past 1.3 I really usually hit a few problems.

I'm watering with the correct amounts for the particular phase I'm in and everything PH and PPM wise is spot on...... If my PPM runoff is constantly higher should think about feeding less nutes?

Can I use NPK of 2-3-3 for flowering phase?I found in the store a liquid fertiliser only for flowering plants with a NPK ratio of 4-6-6, so a lot of potassium and phosphorus which are good for the flowering phase. I was thinking about feeding the plant with this, halving the dose reaching a 2-3-3 ratio. Is it good?
