Foxtailing or not?

I agree with @Grey_Wolf, it looks like she tried to reveg a bit. Possibly timer issues or a solid light leak in your tent?

Waste of nutrients though and costly, it's going to produce disappointing pipe cleaner buds. Smokeable though 👍 bad luck

PK should already be in the base components of feed and some recommendations are to just elevate PK during just 1 week of flower when buds start to grow in length,also use of a bloom boost to accelerate things along all through flower. I only use one system, I can't recommend use a random bottle of this and that. Also consider root health, maybe a Rhizotonic or cannazym type feed. Good luck

High deepsheeba, I found a great article about everything that you need to know to avoid and solve foxtailing. Here is the link: https://www.zamnesia.com/blog-foxtailing-good-or-bad-n1503 Yes it is always good to use a bloom stimulator like pk 13/14 to provide your plant with the phosphorus and potassium that they need to grow big, fat and juicy buds. Happy Growing! 😋

it does look a bit foxtaily to me, might want to try and lower the temps first to see if that helps correct it. Good Luck!

I recently posted a grow question titled my White widow auto is looking a bit dry that shows my what to do with these plants when I had one about 6 months ago. growdiaries.com/grow-questions/48956-dry-leaves
