I think you have the right idea.... take your test sample to a well lit daylight area and with a steady hand you will be fine... lighting is very important to the cri(colour rendering index)
Thank u all for advice. I am always skeptical with new advice because there is a lot of misinformation out there. I hope nobody feels entitled or offended. I am here for a reason.
They are designed for hydro but my research tells me they are ok for soil in lesser amounts. Also I have not used any yet and have up sized pots twice since solo cup almost 2 months ago.
I also have root farm veg base part1 and all purpose part 2. I didn't use them hoping there was enough nutrients in the fox farm soil with upsizing pots to sustain them
Think I over watered them at seedling stage and early veg. Been reading a lot on watering techniques lately. Many would suggest the medium needs to be really dry before watering again. I was only letting the top two inches dry. Also.. I just got my ph pen 2 weeks ago so before that I was relying...
Thank you. I have some green planet cal mag I could use in the next watering . Thinking of using quarter to half strength of recommended dose. I worried about giving them too much
