I had the pleasure of talking with Alex Robles from the In My Grow Show. He runs his own podcast. It’s full of rich content and I highly recommend it. Alex has been growing for many years and comes on the show today to talk about how to diagnose a nutrient deficiency and also talks about calcium and NPK deficiencies as well. You can Alex is a passionate cannabis grower because of his deep knowledge and zest to grow cannabis for the betterment of himself.
