Looks like calcium to me bro. I would always check PH even if it not recommended, just cause it could have drifted enough to lock something out.

Hi, How are the roots looking?
Any sings of root rot?

Hi Crowmax, here some photos of the actual state of the plant.


The measures today.
EC 1.3
PH 5.9
TEMP 18 C


The plant has almost 1 month since being germinated, i think now she looks a bit better than the last week, i have a few doubts still.


* As you can notice i have two tables as a reference for the EC measure, what of them is the correct ? if there is someone correct because they dont inform the same measure.



* As i said before im using micro + grow + bloom from advanced, but im not adding the bloom, because i have just a little of it and im trying to save it for the flowering phase, could this be a problem ?


* What is the correct EC range ?



* Is correct to use 5,5 ph for veg phase and 5,6 for bloom phase ?


Thanks guys this is my 2nd plant on dwc i had a lot of plants on soil and i didn't have this problems, this system is a bit more complex.

18C seems low to me. Is that air temperature or water temp? Have you tried having some insulating material under the reservoirs so roots don't sit in water that's too cold? Cold roots can create problems, so take care about that.
