Yeah I have that book too, it does you no good if you have been feeding it good and then the leaves start showing deficiency. It just makes it more confusing then it really is.This may help.View attachment 882709

Always ph last. Silica if adding first then nutes and then ph the solution.Stop adjusting the ph of your nutrient solution (unless using hydro), if you insist on adjusting the ph you must adjust the water before adding nutrients.
Being able to diagnose a plant problem just from looking at it is a skill I have acquired through my years of growing.Sorry, but you are clearly blowing smoke. There is absolutely NO sign of nitrogen deficiency which would show itself by an overall yellowing of older, lower fan leaves and work its way up. Come on, even newbies know that.
Totally looks like nutrient burn but without more info on his feeding I can only guess it’s a bit too much nitrogen., or phosphorus deficiency.
I don’t know. I’ve never “been feeding it good and then the leaves start showing deficiency making me more confused.”Yeah I have that book too, it does you no good if you have been feeding it good and then the leaves start showing deficiency. It just makes it more confusing then it really is.
It can lock out nutrients in the solution instantly. When you see that cloudiness in the solution when you add ph up that is the chemical reaction that can make some nutrients unavailable.Always ph last. Silica if adding donut first then nutes and then ph the solution.
He is saying if you have been feeding it properly and the plant is showing deficiencies it can be confusing to the grower and they start feeding more because they see deficiencies instead of getting to the root of the problem like ph, compact soil, overwatering, nutrient ratio imbalance, sodium build up etc.I don’t know. I’ve never “been feeding it good and then the leaves start showing deficiency making me more confused.”
Yes depending on the nutrient sources and saturation points. Like calcium sulfate vs calcium nitrate. You ph last this is well known. Also why certain nutrient lines using different sources need 1 part or 2 part concentrates. It depends on the source.It can lock out nutrients in the solution instantly. When you see that cloudiness in the solution when you add ph up that is the chemical reaction that can make some nutrients unavailable.
The plant has obviously been fed good it is big and healthy looking. So why would it be showing signs of deficiency.I don’t know. I’ve never “been feeding it good and then the leaves start showing deficiency making me more confused.”
I agree I just don't feel confident as to the reason and you may very well be right. But it could be due to other causes, most of which your advice would fix. I'm not saying you are wrong just simply that I don't feel comfortable pinpointing it yet because there is not enough infoThe plant has obviously been fed good it is big and healthy looking. So why would it be showing signs of deficiency.
It looks like a big plant in a ten gallon pot of soil. Probably been in the same pot since it was half the size it is now. Which means that it is drinking a lot of nutrient water that leaves behind toxic salts in the soil that will lower the ph over time.I agree I just don't feel confident as to the reason and you may very well be right.

In the words of the mythbusters... Very plausible. Could also be over feeding with cal mag as is kind of the new rage. I am by no means saying you are wrong and there is a good chance you are right.It looks like a big plant in a ten gallon pot of soil.

It will show signs of nitrogen deficiency long before anything elseThis is not true. Very early potassium and phosphorus will show dark green leaves before the start showing other symptoms.
Nutrient burn causing nutrient lockout? Are your talking about the roots. Are you talking due to sodium buildup or nitrogen toxicity? Nutrient burn is typically referred to as nitrogen toxicity in my experience.
It will show signs of nitrogen deficiency long before anything else
Not if it has enough nitrogen! If it’s been fed nitrogen and is going into flower with low p and k, you will see signs of that.It will show signs of nitrogen deficiency long before anything else
If it’s been fed good, salts won’t be elevating the ph. If it has been fed too many salts without flushing it has not been fed good.The plant has obviously been fed good it is big and healthy looking. So why would it be showing signs of deficiency.
ExactlyNot if it has enough nitrogen! If it’s been fed nitrogen and is going into flower with low p and k, you will see signs of that.
I've used cal mag for ever and never had a burnWhy I'm thinking to much cal and not a lockout. But more info is needed by the OP and that's why I won't commit to a cause of the deficiency.
But you typically won't see nitrogen deficiency in flower when the plant needs more k. It really depends on nutrient ratios. I prefer and equal n to k and a but higher k to n in flower
It's not a burn... It's a deficiency. Ca can affect the uptake of K. Let's be honest how often do you see a K deficiency in veg... Almost never... So I agree it's highly unlikely it's due to little available K.I've used cal mag for ever and never had a burn
It would of had problems long ago if it was only fed nitrogenExactly
He is saying if it has been well fed and not showing signs of nitrogen deficiency and you claim you would see that first. Why is there none? Yet it showing a K deficiencyIt would of had problems long ago if it was only fed nitrogen
