One if the best online seminars on identifying plant nutrient deficiency! This was so well organized & easy to follow & understand!

Wow! After watching many armature growers explaining issues with specific plants this a tool box to apply to all growing. Thank you so much for this!

Omg I finally figured out what happended to my pepperomia argyria. Very informative and helpful!

wow, this dichotomous key distinction is so helpful. This provides the context to make plant deficiency information actionable! thank you!

This is the best educational video! God bless you Brian!

Great information, presented in a very understandable way. Thank you!

Thank you so much for posting this. So helpful and detailed

Good stuff, really detailed and properly explained. I would also love to hear a larger discussion on Boron deficiency.

Thank you so much. Very informative

After watching n-number of videos, I somehow landed on this video. Excellent algorithm. Very clear and can be practically applied within an acceptable range of error. Thank you sir.

Very useful! Would love to hear a specific webinar about Boron!

Great video thanks for sharing

Awesome video. Very good explanation

Great Information , Thanks

Thank you! New subscriber!

Nice one

I love these videos, they're the best videos I've found for this stuff. *Where are you getting the attributes and characteristics of each element/mineral etc. from? Is there a PDF or chart or something that I can download please?* Is there a power point file or something if not? :) For example: A chart detailing which elements are mobile, partially mobile, and immobile. And detailing the specific symptoms of each element, so we can compare and 'sherlock holmes' our way through as you do in your examples. Haha. I'd love it. I watched the sherlock holmes nutrient deficiency video years ago and just found it again, for someone else to watch. Thanks a lot.

You guys are very close to popcorn keep doing what you're doing

I have success with cucumbers indoor but dwarf tomatoes have flowers but don't fruit. I guess that there is a lot of nitrigen for them.

anyone know where to get a copy of the powerpoint being used for this presentation?

😎

The book is sold out everywhere, can anyone recommend an an equal or better alternative?

I need to know about sulfur toxicity. I added 3 tablespoons to 3 gallons and my plant turned pale yellow like sulfer deficiency. How should I fix? My ph is good at 6.5

My young protea plants of about 20 cm in height develops necrotic leave turning black .As this spreads through out the plant the plant dies off.I was told not to use fertilizer on protea plants.Any reason why this happens.

Where to get these rare minerals like Zinc , Boron, Molybdenum, etc etc?

I have hydroponics cucumbers indoors and some fruits have white needles. Is anybody knows what is the reason for this?

I'm curious how many of these symptoms are universal for all plants and where they differ? The title says greenhouse plants, but I have potted trees that seem to have the same identifiable symptoms.

Can you give us information how to prepare organic fertilizers. For example for calcium I soak eggs shelves and water the plant with that water. What about for zinc, etc?
