Hi there Ganzi, so basically i took a look at the diary and what i can see is a few things, first of all, underfeeding K. this you can see from the coloful discoloration. Second is calmag deficiency, this you can see from the discoloration on the side of the leafs. finally there is a heat issue, mostly because not enough CalMag. You can go ahead and increase you PK right now. For the cal mag, you can probably double it or more even put 2ml/L no problem. To make the recovery go quicker you can also make a spray with the calmag 1-2ml/L and spray the plants twice a week for one week. Plants need more Mg when it's hot , that's why you're seeing the severe problems right now. Fix this and the plant will recover hopefully quite quickly. hope this helps ! 🚀
