LED and Calmag issues.

ComfortCreator said:
I have not followed every post but VPD will alter how much nutes they take in. If the humidity is high they act differently than at a moderate level, same for temperature. EC will determine what they drink but they also are highly affected by the VPD (temp / humidity).

A very dry room requires them to drink more...a moist room they drink less quickly. Temp alters the rate also.

Thanks, so what would you say I should do with the EC for a 26 degree room and humidty ranging from 60 - 75 ?
 
I despise calmag threads. I hate the word calmag. It sickens me.

At least the "Needs Calmag" comments have slowed down significantly from their peak. It seemed at one time that at least half of cannabis growers believed calmag was a miracle drug for cannabis and could cure all.

Ok but I didn't need need calmag I needed to up my temps and the cal mag issue sorted itself out. This is essentially a VPD thread with a wrong title.

But can you explain to me what turning down the power would do to fix the nitrogen problem?

What I am gathering is I need to lower my EC now that I have improved/upped the temps, seeing that they now have improved nutrient uptake/more ?

The question is why didn't the plants nute burn at 18C days with the lights at the same height the whole time. In fact most of that time they had a lower run off EC than input by 0.3 - 04 EC. Mind boggling, but I need to know why.

Turning down the power won't fix a nitrogen problem, that's why i suggested also reducing the nitrogen amount in your feed.

I wasn't commenting on any of your posts. I was referring to the title of this 3 year old thread started by someone that hasn't posted in years. "LED and Calmag issues."

Glad to see you got whatever issues you were having sorted out.

I can't lower my nitrogen content, because it is included with all my other macro and micro elements. Should I lower my EC to 1.3 ?

What will turning down the power do?

My original issue post number 275 has a lot to do with the thread. But to understand that you'd have to read every comment on here. I never understand why people get so riled if someone revives a old thread with, especially one like this with such invaluable information. I thought it was the best place to start.

VPD is a range you stay within for best results. At 75% that's a bit high so I would try to keep it to 70% max.

Your EC is based upon a plan and then looking at the plant for feedback.

I wouldn't adjust EC based upon VPD. I would slightly adjust the environment to better fit your plants feedback.

If it seems to be burning slightly, running a slightly higher rh% and a slightly lower temp can help mitigate potential burn. As can lowering light intensity temporarily.

EC in a properly dialed environment is purely a read of the plants health and your experience applied. There are guides but every strain and pheno reacts differently.

So the EC advice given earlier is correct, these guys know how to read plants. The # is just a marker to use to guide your feedings. 1.2 or 1.6 or 0.7 is a means to measuring input and then reading the results and adjusting accordingly.

Plants react over several days to a week to changes, so dont expect major recovery to any stress in a few hours or just a day.
