So I didn't think this should go under plant problems only because I am a first time grower. The pic is of a leaf that was on a plant that finishes week 6 of flower on Sunday. I am noticing though that the plants I have in veg are starting to get the grow spots and yellowing, as well as brown tips also. I'm growing eveything in Canna CoCo and I'm using Cana nutes throughout. I've thought about changing nutrients as I'm not sure the Canna nutes are really worth the price. As for the yellowing and spots, I'm not exactly sure what nutrient they may be deficient of.
Any help would be greatly appreciated.
