    Leaves die off from lack of sunlight. I had a node grow several branches after topping. The smaller ones that formed didn't grow and eventually died. For nutrients it's best to use every bioactive element, if it's essential to people then it should be good for plants. Aside from NPK and secondary and micronutrients, the ultra trace ones can boost growth.

The dyes added to fertilizer will be a good indicator, also its hard to over fertilize with high phosphorus, high nitrogen will really cook a plant but you can see that coming.

    ​@@jukeboxgaming1343you are incorrect. The measurements of a liquid or powder wouldn't mean anything if you don't use the same since they won't have the same concentration. However when you mix your element P (potassium) in a form of liquid or powder into your water whatever its concentration you just have to measure your mix and be at 30ppm, simple as that and don't forget your PH after aim for 5.8 in hydro have fun

    ​@@jukeboxgaming1343it's more of a guide. Not a rule. I'm sure you can drown a plant with nutrients and it will be fine. Like different strains can handle different levels of fertilizer. Pale green plants that just got moved outside in direct sunlight can handle way more nitrogen than a plant in the shade or inside on a window with a few hours of direct light a day. Think of sunlight bleaching the leaves, and at night the nitrogen replenish it.

    Athena Cleanse increases the Oxidation-Reduction Potential of water. ORP indicated the water's ability to clean itself, without the need for toxic substances like common sanitation products. Cleanse is a stabilized solution of Hypochlorous acid, a mild acid derived from sodium chloride and a proprietary electrochemical treatment process. The result is a unique, plant-safe chemical with powerful oxidative properties to keep your root zone clean and free of unwanted organisms, mineral scale and biofilm buildup. These special properties are key to improving both mineral and oxygen availability in the growing media.

    Thanks for the video, Bruce. It's nice to finally have some kind of number to shoot for. But I have a few questions. And I hope you or somebody that works with you can give us a little more insight on this 30 ppm. I mean most of us know that when we introduce our cannabis plants to 12/12 lighting ( Flowering). We should give a boost of P. I use powdered nutes and I mix all my nutes myself. I don't use any premixed bottled nutes. And what I have always did was the first 4 weeks of 12/12 . I would just add a extra 1/8 of a teaspoon to my solution. I can't remember off the top of my head,what that brought the ppms to. But what I always thought was this helped increase bud sights. Anyway my first question is. What ppms of P should we be running in veg. And next is when should we increase the amount of P. And should we increase it all at once to 30 ppms. Also from what I understand is that P gets locked out very easily. So if we are increasing the amount of P. Should we be adding or increasing something else. So the P doesn't get locked out. For example, when I give my little boost of P. I give a little kick of aminos to go along with it. Now my next questions are going to come from this example. Like I said I only gave a boost of P for the first 4 weeks of 12/12. Then I would cut that out. Then I would give a little boost of K from week 5 till harvest. So now should I still run the 30 ppms of P all the way to harvest ? Because you said that the flower will have 1 percent of P in it. And that just seems like a lot. And what kind of effect is that 1 percent going to have on the quality of the flower ? Or is that the norm ? I have a few more questions. But I'm going to stop here. I'm sorry that I went on and on. I just find this very interesting. I just want to thank you and your crew for all the hard work that you all do. And to thank you very much for passing all your knowledge on to us. Speaking for myself. I truly don't think you understand how much you have helped me to become a better grower of cannabis. Well for that matter, a better grower of everything. And I'm sure I'm not the only one. Again thanks. And take care. ASS OG AeroSystemsSea OfGreen.

    Cannabis leaves survey range for phosphorus is 2.4-4.9 mg/g. During vegetative phase, plans accumulate P in their root to prevent P toxicity in the leaves. This means 9.6 mg/L phosphorus is adequate for optimal growth in this phase when water use efficiency is 4.0 g/L. During reproductive phase, plants can accumulate 10 mg/g or more of phosphorus in the buds. So it is advise to double or even triple that 9.6 mg/L to support phosphorus demand by plant in this phase. I currently feed 11.6 during vegetative and 29.0 during reproductive phase till a week before harvest. Cannabis yield is unaffected by potassium in the range of 75-175 mg/L but canabinoids decreases as potassium increases. I currently apply 95 mg/L potassium in the entry grow; no boost in any elements except for phosphorus. These numbers are about optimal yield not quality. Quality decreases as N, P and K increase; the dilution effect by more growth and yield.
