Leaf diagnosis

I also change the light setup instead a 400w I am w 2 250w, it’s less intense but w a better cover over all

@organoman are immobile elements / trace elements available tru Biobizz Grow, bloom, top max? I also have here calbor mag , top candy and molasses

Had a hard time watering, my first grow also w 11l pot , I use to water 1,5l and get a 0,5l runoff now what I found is working best is 2,5l w a 0,8 runoff....that said my substrate got nutrient saturated and the girls underwater I flush 5l each girl, they like it, now back on feeding The leafs were showing these signs before I flush, now it’s not spreading or getting worst

To me it looks like a combination of deficiencies due to the lack of trace elements, which are "immobile" micro nutrients and this is why the newer growth is affected and not the lower leaves. This is due to the plant "running out" of these trace elements, causing the new growth to suffer. Trace elements are known as "immobile" nutrients, if there is an insufficient supply, the plant will continue growing, but can not supply these nutrients by transporting it from other areas of the plant, as it can do with the major nutrients, nitrogen, phosphorous and potassium. When there is a lack of or an over abundance of these "major" nutrients,(NPK) and the fact that they are "mobile" nutrients, means that all leaves will show the same symptoms of either excess or deficiency. Luckily a deficiency of iron, manganese, zinc, boron, copper etc, (trace elements) is relatively easy to correct and the best news is that the leaves that look damaged now, will actually recover back to normal health and colour, once trace elements are boosted into your substrate, which is the exact opposite for damage caused by either an excess or deficiency of any of the major nutrients, for once the leaves are damaged there, they stay damaged. Trace elements, either in liquid form or in granules are easy to buy at any garden centre and are fast acting. Volcanic rock dust is also a good source of trace elements, but for the quickest remedy, liquid/soluble trace elements are your best option. Heat may cause the leaves to curl up, but will not cause leaves to go yellow. I live in an area where summer temps often exceed 40 degrees Celsius for 3-7 days at a time and none of my plants growing outdoors, have ever got yellow leaves at the top of the plant as a result of these frequent "heat waves",(4-12 times each summer), in over 35 years of outdoor growing.

Hi there,Plants are less defensive during flowering stage and they are using all the energies for bud production.They will show heat stress( mostly if temp is above 25C or intense heat at buds,hot spot heat stress)and might show some symptoms or leaves discoloration(may be different from strain to strain.As long as I can keep my substrate pH in proper range and proper feed, I will not worry a bit about those symptoms and discoloration).All I would do is making her as comfortable as I can until harvest and focus on buds for pests, mold or rot.Happy growing... ✌️

Looks like heat issue stress. Lower the temps give good air movement

The plant is suffering from light/heat stress this is why it seems like it's only affecting the top part of the plant, this is also why the leaves look they are shaped like a "taco", backing the light off some should easily fix this issue.
