26 hour day cycle?
ever done a weird light cycle for photo plants? like 14 hours of light then 12 hours of darkness then keep repeating I know that this is longer than a normal 24hour day. 1. 12 hours of darkness is what makes weed start flower. Do weeds know days r 24hr? Can a 26hr day cycle work

Black tips and spots on the leaves
I'm having problems with the leaves. I estimate that the plant has about two or three weeks left to live, and I don't want to have issues now. Some tips are darkening, and spots are appearing on the leaves

How to dim a Sansi LED bulb
I have a 10W Sansi LED bulb for my grow, but I would like to be able to dim the light since, having limited space and needing to place it close to the plant, I'm having issues. (https://www.amazon.es/SANSI-Bombilla-Espectro-Completo-Invernadero/dp/B08P1RL7KC/ref=asc_df_B082PSBP68

Is my LED too close or too far from my plant?
So this is my first grow and it feels like she’s growing a bit slow. Currently at day 10. Distance was 62 cm. The LED is 100W. Now the distance is 57 cm. I’m wondering if I’m just impatient. Is this distance appropriate? How is the growth looking?

Nutrient deficiency?
Dear grower, I am having an issue with slightly yellow leaf tip. I only used BioTabs Plant Perfect Package. I am suspecting she needs some extra food, but I don’t want to over feed her. Considering giving her BioBizz Grow (little by litttle). Do you recommend this technique?

Leaves keep turning brown and yellow
It all begann with what I thought was light burn. I then considered it CalMag deficiency. Giving it CalMag did not stop it. My current guess is too low pH due to strip inaccuracies, so I gave it around 8 today instead. What do you recon, why could it keep getting worse?

Sudden Leaf Yellowing – Lighting Issue or Something Else?
Hello! Yesterday, I noticed the top leaves turning slightly yellow, but today it looks dramatic. Check the pictures—leaves are yellowing and drying out rapidly. It’s only affecting the central leaves, so I suspect a lighting issue, but I’d like to confirm before taking action.
