Lighting 1st LED grow. 2 think different in shared DWC reservoir. Scrog or not to scrog, that is the quest

I Seem to be having Calmag issues already. I know a lot has been written about it, I have read a lot of it. But I don't understand, I have calMag in the res. I tries foliar feeding last night. I hope it helps.

Hay bro,the lights causing calmag def is something that happens in late flower so your issue may be something else...how's the PH and res temps?

Hi taNg, the ph is sitting at 5.8 and the res tep is about 25C

Res temp needs to be below 21c bro that may be your problem.

I think I remember some of the top boys saying that underfeeding will accelerate cal/mg deff .Something along the lines of the plant will prioritize feeding on the most nutritious nutes if its deprived maybe ... ?

Also remember someone saying cal or mag or both are locked out @ 5.8 or above & to keep them just under that in veg .That may be a reason for the deff as well .? + what TaNg said :

2 think different in 50 ltr dwc res

20 days from germination

Two think different.
PH 5.7
PPM 730

I am doing some LST on the main stem using bent wire. It seems do be doing the trick so far! Lower branches are stretching up..

LED lights can also cause an iron deff (just something to keep in mind )

Looking great bro,looking like a killer pheno.

thanks for dropping by taNg. I am keen to compare the LEDs to ml last few HPS grows. I got 16oz from 1 think Different a while back, so I am trying again with the same nutes.

I seem to be getting some tip burn on the new growth. Am slightly concerned as my PPM is only at about 800, with the water being at 300 initially. Any suggestions. I am trying to keep PH between 5.6 - 5.8
