Right now I’m using the Afgan autoflowering strain in a Vivo 2 x 4 tent with 2 Vivo lights set at 100%.
Ventilation is through a 4" fan at 45 cfm.
Using Sohum soil.
I’m not getting any runoff; depending on the meter to tell me moisture and pH levels.
Adding water when the meter falls below 6 or so, and using the pH down shown in the photo to keep pH levels in the 5.5 - 7 level.
Having a problem with yellowing leaves, and clear bead formation.
Depending on the meter too heavily?
Too much or little water and / or pH down?
I’m no means one to give advice just going off what i did for my first grow, i had about 20% water run off steadily measuring over 1000ppm i am also using fabric pots and fox farm happy frog soil with a 2x2 tent ac infinity light same fan as you as well
Sorry to tell you this Growmie but those meters are super inaccurate… good for a house plant. Run off is critical to prevent root zone issues from the salts in synthetic fertilizers and testing the PH and PPMs in the run off wi let you know what each are in the root zone. Critical info to know and without it it’s a guessing game on how much to feed and if your PH is in range for nutrient absorption
