Thank you! You've explained it well!
I'm growing in promix
I'm watering using A tiny metal watering can
I was using a combo of these nutes for my vegging stage
this to balance my ph
And finally a variety of distilled and spring waters for food
Here is my opinion.
1: Start lifting your pots to feel weight. Before and after water. Remember you have dense soil mix that holds water at the center while pot feels dry.
2: Get pens and feed about 500PPM every other watering. Always follow label instructions for when to add. And PPM at end otherwise.
3: PH to 6.4 for the first week of using pens.
$: Soil should be hot still. Give her a chance to relax and see.
6: Use city tap water. Distilled and spring lack minerals. Or are added to your tastes. Not plants.
Best wishes.
