Thank you

Using a flowering formula - same blend on all 4 plants, only the Purple Power doesn't seem to like it

Too much nitrogen. You plant wants lots of potassium and phosphorus. Very little nitrogen after the stretch. The clawing is nitrogen toxicity, the spots are potassium deficiency and possibly phosphorus deficiency. Checking substrate ph is always a good first step before adjusting nutrition to ensure a good growing ph range.

In coco only is your run off ph 6? You should be at 6.2, 6.3 ph in and coming out. I grow in coco. A cal mag is ideal as well 1ml to liter of nutrition. Are you keeping coco wet. It needs to stay 90 to 100 percent saturated. It is hydro growing in a bag. So lots of water in coco growing is required.

Hello you can defoliate because you are still in the week 3 of flowering. So do it before it is too late but don't defoliate too much because defoliation is a stress. Just remove leaves that makes too much shadow for lower branches. Good luck. Otherwise your plant is very nice. Buds are frosty yet. You will have a beautiful harvest. Bye

If the plant is healthy you can defoliate still don't go too mad just remove anything blocking lower bud sites you don't want to stress them out but I have defoliated at this stage without issues
Best of luck with your grow

exfoliate is what you do to your face, not to your plants, never HST in flower growmie , does that makes sense? :rocket:
