How to control EC
My EC is higher then recommended or I'm reading it wrong. I have been told to add water to my reservoir to lower EC, yet with my well water the EC is already high. Can someone help enlighten me? Using a hydroponic circulating system (DWC with a top feed).

Nute Burn?
Upped my nutes this week per the BioBizz Lite Mix plan...but is it too much? The tips of a few of my leaves are ever so slightly yellow with crispy looking tips. Too much? If I need to dial back, which nutrient do I dial back on specifically? Or just dial back on them all?

Autos and Nutes?
When growing autos, what nutes and how much do you like to use? I use about a quarter strength of Nectar for the Gods series. I've noticed a little nute burn but not bad. Now do nutes stunt growth in autos or is it really play by ear?

I’m out of BioHeaven
I’m out of Bio-Heaven and I wonder whether it’s worth getting some more, given that I’ll probably flush the plants within a few weeks and only use water then. Plus it’s quite expensive compared to BioGrow, BioBloom or TopMax… Any ideas or maybe an organic substitute? Thanks!

Fert Switch Veg/Flower Timing
When and how do you switch from Canna Vega to Canna Flores? Feel free to share any tips. What are your "signals"? Do you suggest a hard switch like in the Canna schedule, or do you prefer transitioning by mixing the fertilizers? If you need more info, please check the diary.

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?
