Anything is better than nothing at this point. I’m not familiar with that nutrient.

Thats the veggative stage nutrients. and never spray the plant under the light. always feed the soil. if you want to keep that bottle then you also need a bloom phase.
I use mega crop nutrients and @greenleafnutrients can give you allot of information about the product. However, its a very easy to use nutrient and its good from seedling stage all the way to flower.
I use the two parts Mega crop, but they also have a single blend. https://greenleafnutrients.com/

you will need a bloom/flowering nutrient as well.. if you plan on growing again and again than some calmg too, as it’s needed 3-4? week of flowering.. but get some bloom nutrient.
so when it’s time to water feed the plants 5ml of veg per gallon not litre..

maybe even 7.5ml per gallon or somewhere in between

Hmm...I have also noticed from the lower branches that they are turning purple, which is an indicator of chronic over watering (which could have been from spraying them also)….which means you need to water/ feed them but leave a period for the soil to dry so the roots can look for the nutrients. how often are you watering/ feeding them...just curious...and that temp being 2?
