Lighting LED and CalMag discussion.

[Clix]

The way it was explained to me is that LEDs are more efficient at utilizing nutrients so will exhaust the amount of cal/mag in most nutrients. Kind of made some sense when you consider that most nutrients have been developed for use under HPS lighting. When bleaching occurs with LEDs from the lights being too close, the fix is to give a foliar feed of cal/mag. It's an effective fix, so that would seem to give some credence to that theory.

Question. When flowers bleach do you still foliar feed. or is there another method of dealing with this? I ask as I no longer have any room left to raise my light lol

With the light situation you could have the lights come in from the side or front,if you have something to secure the hangers.I have mine set up like that. I don,t foliar feed,someone will come along who does.I saw taNg with his LEDs he goes from all different angles.Good luck dude.Peace.

Supercrop, lst, etc.
Ive done it right up to harvest in my cabinet.
In fact i think it helped.
Good luck

Still no solid fix for Ca def using leds? AN support told me that we think it's the leds fault when actually we are feeding wrong. They say the problem is the way we water. We need to water with runoff cause the soil will get salts buildup. In case you can't flush from time to time give em just unPH'ed water. When using pH perfect no need to pH the water... 2 weeks ago they told me AN don't usually leave salts...
Here is the last mail.


What I suggested in the last post was that by the fact that as a rule you do not feed them to run off, it may cause the medium to have different conditions at different places in the container. A flush to the beginning of run off will create even growing conditions in the medium for the plants to grow in. When using the pH perfect formulas, there is no need to adjust the pH when giving them just water


Edit. I am taking their advice though I'm sceptic about this ..

1 1/2 years using 6 different LED lights to grow 15-20 different strains and I've never had a cal/mag issue not related to PH issues.

Its not the LEDs!

Thanks!!!!! What's the best LED you have used ??

Pop do you use Advanced Nutrientd and do you water to runoff?

 

[pop22]

I use organics only currently. I've done DWC with GH nutes though, also done with LED.

And that makes me wonder if it is related to LEDs and nutrient brands hmm.

Pop do you use Advanced Nutrientd and do you water to runoff?

I'm no expert do hopefully someone can answer you better but this happens on one of my girls and I starting feeding plant magic calmag every feeding and she's healthy and no more has appeared so I would say yes imo
