I think it looks like nutrient burn. Not sure about your nutrients, but with mine I am at .25 tsp gal and about a week ahead of you. I suggest a flush with ph'd water or a very light nutrient mix.

Looks ok—- do you spray a foliar or IPM? That can happen from water sticking around a little longer and burning the leaves under the light.
It can be a little nute burn, but hard to say

I can not take out of the tent to the darkness more than 4 at once and wanna hear your suggestions before I go with yellow sugar leaves or some amberish :DI read something about harvesting immediately (not to crap the flower) when sugar leaves start to turn yellow and I have some! On the other hand, I saw some trusted videos that has some yellow sugar leaves. I want to ask you if you have any experience with this issue?

Magnesium nutrient lock out, triggered by too much potassium ?@Burmese
Thank you so much for your help. 🙏😊 I think it was a magnesium nutrient lock out, triggered by too much potassium. I sprayed some water with Epsom salt on the leaves and it looks like it is getting better. 👍😉Week 4

Natural or Problem?Is this natural yellowing or is there a problem? pH to 6.3 and runoff is 5.7. The stem is awfully purple, watering/feeding is where I struggle. 1st pic - 4/21 and 2nd pic - today(4/24). Seems to have escalated over the last few days. Do-si-do auto about 10 weeks.

Pruning dilemmaI am noticing that some leaves are turning yellow at the very bottom of some plants, I think that there is not enough light coming through. So my question is (I did only LST and FIM --> on the main branch on every plant) should I start to prune some branches to empower top part?

Yellowing leavesLeaves seem kinda yellow on one hand. The bottom right hand corner one looks like she needs CalMag but I'm not sure.
All the photos have been taken under the same light.
Used to over dose the nutrients to prevent burn but continually gave them 1mL/L calmag each.

Deficiency or Overthinking?Wondering if this is some sort of deficiency or maybe I’m overthinking? I know I overwater sometimes and I’m trying to get that under control however my other plant doesn’t look like this it’s more solid green. Temp is at 75 daily and humidity is 35-40%.
