Hey there everyone. I'm 27 years old and i live in the northern part of europe.
I'm new here & have been growing one plant, in about a year ago, though it was more of an experiment/learning the phases of her life.
Now I'm more "organized", concerning lights, airflow, watering, nutrients e.t.c.
My growing (indoors) space is 40×40×120cm, so i don't have a lot of space to play with. I germinated three seeds (blue dream) but since i realised my limit in space, i treated 2 of them pretty rough. For example i topped one of them when it only had one node...
Now I'm having two plants in veg-phase and they seem to enjoy their life so far (now vegged for ~5 weeks) I'm using a LED-light, 0.1kW and the temp is ~19-21°C at "night" and ~24-26°C during "day". Humidity ~55-60%. I use 100% coco-fibre for one plant, and the other one is 100% soil. That one in just coco seem to be in need for some more N. (Yellowing tips and tiny dots). So i gave her 2ml 20% N (canna) and also 2ml trace elements, also canna, while watering her.
Now to my question...I do have a large amount of chalk (calsium/magnesium) and i was wondering if it's possible for me to mix a very small amount of that chalk in to the water i plan to water her with? Just to balance the Ph. I mean, it couldn't do any harm at least, right?
I'm grateful for any answers concerning this & and I'm so happy that this forum exist
Cheers!
