rapidly yellowing top leaves
btc21hkstarted grow question a year ago
Week 7 auto. She was all green a few days ago, but top and bottom leaves now rapidly turning yellow. Soil run-off is 5.8PH and 700ppm, so I suspect some sort of deficiency here. Any ideas?

It looks as if it's only happening with the bigger older shade leaves in the photos you have provided with this question. Not every plant goes for 8 weeks during flower cycle, this could just be its late flower fade. Do you know the cultivars name? If so try looking up other diaries on this site for the same cultivar and compare their late flower stage with yours, try to find one from the same seller of the seeds so you can eliminate some of the deviation in genetics. Also environment plays a large role on expression of genetics, so when looking at other diaries make sure to check how close your environmental settings are to theirs.

Week 7 in flowering is normal for the leaves to turn yellow, your plant is coming towards the end of its cycle and the plant is using up all the Nitrogen left in the leaves.

Your feed should be twice what it is. Mainly potassium and phosphorus. Not sure what your substrate is so hard to say if ph is right. If in coco it is if your run off ph lines up.

Day 20 Flower. Leaves curlingLeaves curled over 12 hour light cycle. Ph 6.0. Ppm 950.
I have been battling ph drop for a week. Lowered Ppm to 900 from 1100. Seems to have stabilized the ph and now the leaves are doing this.
I’m looking to do the day 21 strip of most leaves tomorrow. Should I be concerned?

What do you think the problem could be?There’s something going on with some of these plants and I can’t seem to identify the problem so far. I have been doing a lot of research and I’m in a process of elimination at the moment but the plants growth hasn’t been affected. I will continue to try treat the problem.

Help: potential over fertilisation or over waterningI used Biobizz bio grow, 2ml/L and sprayed them more than usual. The tip of the leaves is getting yellow. 2 plants have the leaves pointing down and seem more textured and tick. The other 2 (the biggest) seem better, but the yellowing of the leaves is more evident.
