Since I have found Harley's lectures here on KZbin I have completely stopped looking online and wading through dozens of people's opinions concerning one subject of plant growing that would get me nowhere. I come here and my question is answered and the problem is solved. Thank you for these lectures. They have saved me much trouble.

[@MrDylanryan]

Bob Wags me too. I even looked up his university. I might take his online courses. I already am adding his supplements with my nutrients. My plants love it. I want to learn how to spoon feed better.

[@estebansiordia8536]

I was studying plant science in college but didn’t finish , this man is real deal

[@2511jeremy]

Just bought some products from him and i cant wait to use them the RAW line is going to be awesome for my plants

[@2511jeremy]

It was awesome well worth it

[@subhashrayate7304]

Sir I would like to thank you you are an absolute genius you have explain things Innoway I can understand better than anyone else. I loved the raw soluble, but cannot find it anywhere anymore. What happened? Keep up the great work!!

[@NPKIndustries]

The RAW line is really taking off! Ask your local retailer if they can order it for you, otherwise there are online retailers that can help you out!

[@elliotalders0n]

Excellent videos, pretty informative. 🇮🇳

[@NPKIndustries]

We're glad you enjoy our content!

[@subhashrayate7304]

For efficient transport of Fe, zn, Cl ,Mg into leaves ,which cheleting agent is better(For floral application) amino acid or fulvic acid and what should be the rate of application per liter of water with nutrients?

[@thewebtrellistrellis7742]

When working with dry nutrients I realize that I wasn’t mixing it correctly after following the jacks nutrient formula I realized the calcium goes in last.That solve the issue to my leaves turn yellow the chemistry wasn’t right on the mixture Because I wasn’t giving it a thorough mixing now I use a pump inside my water at the bottom of the barrel to make sure it is thoroughly mixed in other words I was putting in all the correct things at the plant need it but it wasn’t binding correctly and that’s where my issue was happening hope this helps anybody using drain nutrient

[@johnpaddy8195]

Hi, Does this apply to auto seeds?

[@fayjason]

Are all trace metals like calcium, manganese copper and iron all immobile?

[@benchamingabriel5218]

Can we mix fulvic acid/ humic acid with pesticide spraying?

[@andrewmitchell8401]

The real Dr.Greenthumb!

[@MudFlap62]

The RAW line seems awesome. Do you sponsor any weed tubers ? Would love to see a growers opinion. Keep the videos coming.

[@NPKIndustries]

not at the moment :)

[@martinnunez4919]

Id be ur perfect candidate. I’m currently building my grow space for indoor I’m going for 3 light rotation and been growing outdoors for over 5 years( we’ll meds over five years, but have love and passion for just growing) i found ur videos and wow been impressed on ur knowledge and pointers u seem real genuine about ur caring for other people’s knowledge of understanding the idea of better healthier plants because at the end of the day we’re all trying for perfection and balancing all the info is becoming a dance u my sir are a dance instructor

[@flaweddad7500]

I'm growing in a mixture of peat, coco and soil. Can I use your RAW products for soil? I explored the website and only saw a recommendation for hydro. I'm assuming that I can but might need to change my dosage?

[@NPKIndustries]

Yes you can! Our bases work great in soil and we also have an All-in-One blend for both Grow and Bloom

Sup Harley Smith I'll see you tomorrow at the tree house in coldwater

[@avenger996]

Should I use Cal/Mag during heavy bud development.

[@macrostiffproductions2978]

IF your Using R/o water you might wana use a bit. Tap water than no need

[@TiltMachine]

3:25 so is tap better than RO? Or other filtered water?

[@NPKIndustries]

Not necessarily better, but easier to be precise

[@RaveGamingCommunity]

I have found that to be true the yellowing start at the tips of the leaf you can catch this early there are a few other reasons why this can happen. 1. Over watering and feeding. 2. High PH I try to keep my ph in a low to mid range for any of my plants 5.8-6.3 in most cases. 3. Nitrogen Deficiency 4.Bug Infestation Spider Mites And other sucking bugs ut sometimes it is not easily seen by the leaf it could be under attack from the root zone and hemotoads are the best way to ride your self from trips and Rust Gnats All natural is better then any pesticide that could harm you so I personally use YUKA with the hemotoads or i use Neem Oail and peperment and a all natural soap to help me of the problem on the leafs zone I have used lady bugs as well but if you do not catch spider mites quick enough they will take over your crop and nothing is a 1 spray fix you will have to spray your plants 1 or 2 times a week for the next 2-6 weeks to make sure any eggs that hack die you can use sand about 2 inches as well to stop gnats most of the time i will use 1 gallon of water then cut it back to 1 quart or 2 quarts most of the time i drown the gnats if i se they keep coming back I use Sand..

[@NPKIndustries]

Nice tips! Thanks for checking out our videos!

[@liamduncan732]

I live in Poland the only Ph I get to buy is for Swimming pools I need to have them in much smaller size or can you tell me what I should do to make it safe to use on veg?

[@aaroneckard297]

Baking soda and Cleaning vinegar

[@charlescarlson8283]

Do you think it would be ok to put 500 PPM of NPK bloom in over head watering on AG pumpkins?

[@NPKIndustries]

yeah, that doesn't sound too extreme :)

[@staffsergeantmack-safehave8303]

I ride side car. To HARLEY

[@jackdobberstein6369]

i'm trying to figure out why my plant stopped growing and has dimples on the leaves. it's a starter plant about 4 inches tall. anybody?

[@missanna208802]

I don't know if you ever figured out this issue, but I had some rescue cattleya orchids that...ok normally they make at least one growth a year, these didn't make any for a year. They just sat there. I finally thought that they might have 'hidden hunger' and used a bloom booster on them for the higher p and k and in a few weeks, they had ALL started new growth. I don't know what kind of plants you are growing, but sometimes changing the light schedule can help too. If you find out where the species grows in nature and when it grows (usually during the rainy season), all you have to do is figure out what the day length is at that latitude at match that day length, though I prefer to drop them to 12/12 for a month beforehand to 'restart' them, then raise the day length up over a period of a few months. It's one of the tricks we use to switch plants from the opposite hemisphere to our own light schedule.

What is ureic nitrogen?

[@martyrawdog]

piss

Out of a million growers I bet your protected ideas are already used by 99% of the good growers out there. Cmo. Man.

Roots out my ass . Brix count through the roof. Thanks harley . With the abundance of natural kelp on my beach each winter I am never without . Too bad I cant market it. Tons onto of tons of natural kelp . Fills my beach every winter about 8 ft high and 20 ft thick

[@devinhaueter727]

marijuana is great I can learn about the science of plants and smoke da herb!😉

[@NPKIndustries]

MMJ is an amazing life form. I cannot think of another plant that will develop so radically different depending on fertilizer, grow methods, etc. The more you know, the better you'll grow!

[@devinhaueter727]

NPK Industries do you have any tips for a rookie

[@NPKIndustries]

watch as many of Harley's videos as possible, and pay attention!
