The deficiency slowed down, but I still spotted signs on some new leaves, so again tried to feed with higher dose of minerals.
Day 40 update: The deficiencies are still getting worse. I got biobizz calmag and added to two last feedings, but the deficiencies are still continuing ... Beside that the plant looks fine, lot of bud sites and it fills the box completely, so 🤞 the harvest will be still good.
@Chilipadi, Yes I did for a few feedings (Biobizz calmag) but I now think that was not the main problem. It turns out it was caused by me not using all 3 parts of the feeding (only 2). It seems to have stopped getting worse since I went back to all 3.
@Chilipadi, Thanks for the tip, but I do not think so. Its the same light I used for last 2 grows, where the canopy was even closer than it is now, and this is the first time I saw these problems.
@minigroww, yeah been there too.. i grew soil too with lots of problems then went pure coco with only floranova and boom 100-140gram per plant everytime, only have to correct the ph to around 6.1 and yr golden
@Chilipadi, It seems to be. All of the buds on mine started to foxtail around day 50. If you look at the strain page here at growdiaries (growdiaries.com/seedbank/fastbuds/lsd-25) I think you can see foxtails on many of the pics.
