Hi all, apologies for lack of updates (if indeed anyone is watching, lol).
This is day 71.
Would appreciate some input from an experienced grower. Over the last couple of days, the leaves have begun to turn almost completely yellow, with faint purple edges.
I am unsure what the cause may be though. Nutrient burn? Nutrient deficiency? Over watering? Underwatering?
As this is my first grow, I have no frame of reference. The plant itself has been growing steadily, and seems to be developing normally. I'm nervous though that it's about to die just weeks before harvest. Is the yellowing normal when the plant reaches the end of its life?
Further, I done research on when the best time to harvest is. ie. Looking at the pistils, the trichromes etc, but can anyone tell me roughly how far away my harvest date is?
I'm looking for the sativa type energy high, rather than sofa lock, and as I understand it, the longer I leave it, the more cbd will be produced. Is that correct?
Dunno if it's relevant, but I'm using 300w Viparspectra LED on a 20/4 cycle. No nutes now as I read somewhere that I should lay off the nutes when harvest time is near.
Lot of questions I know, would be grateful for any tips.
Apologies for shitty pic. Phone is being a twat.
