Overconfident newbie grower has some questions

[Mañ'O'Green]

Thanks for the tip! Do you know if any of the following is better over the rest as a foliar nutrient?

Hy-pro Spraymix
Cannacure
Biobizz Leaf Coat Spray
Dutchpro Leaf Green

Or can't it hurt have several at hand?

I have studied Harley Smith's methods and he uses NPK Industries Fulvic Acid 5 parts to 2 parts Kelp, Vitamin B, Aminos and yucca powder as a stimulating foliar. Optic Foliar is an AFN Vendor and I will be sampling their products soon. @Waira has used at least some of their products and has nothing but good things to say about them. The idea here is to have something on hand if needed because waiting for delivery is wasted time when the plant needs help. This goes for cannabis approved insecticides and fungicides as well. If you feed good balanced nutrients at the proper PH these products can just sit on the shelf.
