Not really. More preemptive really, Blue suggested it https://www.thctalk.com/cannabis-for...at-autos/page5
A couple have started flowering, so might just forget it for now.

Sulfur is a secondary macronutrient, otherwise known as, a macronutrient.
At least 17 elements are known to be essential nutrients for plants. In relatively large amounts, the soil supplies nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur; these are often called the macronutrients. In relatively small amounts, the soil supplies iron, manganese, boron, molybdenum, copper, zinc, chlorine, and cobalt, the so-called micronutrients. - Wikipedia
I've a lovely array of collegiate and professional sources at the ready if you'd like to discuss the point, though.
Cheers,

Y'all cannabis growers try to change the rules. Quit it!

Kelp and Fulvic acid are both natural organic bio stimulants, and their are some bonuses to using them as a foliar spray, rain water is natures foliar spray and contains trace elements of minerals as well. Yucca just acts as a wetting agent, and depolarises the water so it doesn't bead on the leaves, and you don't get light burn.
Foliar application is no doubt the most efficient and effective method of administering liquid seaweed to your plants. Kelp extracts are 8–20 times more effective when applied to the leaves than when broadcast on the soil.
Like I say I will foliar spray only in veg, and the plants do seem to like it
I had a delayed hutch my reply would trigger an unintentional debate after I sent it. Reason being Macro, Micro and Secondary are terms used differently depending on the source or author.
I don't care much about anything other than whether a nutrient is "mobile" or "immobile". (Thanks barney_b...I always wanted to say that! )
No need to discuss 'cause its all academia.

It says a lot about a person when they can take a step back, breathe, and respond without emotion. I respect you the more for it.
I think it IS safe to say that NPK are the super-macros But that's bro-science. Let's just live there for the time being. Perhaps it's in the same vein as calyx/bract and pistil/stigma. But the cannabis still grows and the weed still gets smoked.
Cheers brother.

..."any type of nutrient deficiency...
Do you use foliar spray as part of your regular feeding schedule, or just when you have a nutrient problem?
If so, what nutrients in particular have you sprayed your plants with?
