As far as I know, Calmag is recommended for plants that we grow in a box under LED lighting :)

To solve the problem of leaves, we did not notice any difference with an ec of 0.8 and 1.4. (group separated 2 weeks ago) :/ Any propositions?
In hydroponics is it common for you to use power roots, green sensation, cannazym or the hydro A&B product really enough? Thank's

Yellowing leavesLeaves seem kinda yellow on one hand. The bottom right hand corner one looks like she needs CalMag but I'm not sure.
All the photos have been taken under the same light.
Used to over dose the nutrients to prevent burn but continually gave them 1mL/L calmag each.

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

best leaf insects repellentI have found a few bad insects on my plants past weeks. Does anyone have experience with neem oil? Is it worth a try or would I be better of buying something else?
White vinegar with dishsoap didn't help much.
The bugs are: grasshoppers, stinkbugs, spidermites & fungus gnats.
