What do you think is the problem here? I only gave...

Hia, I do think that it is an excess of nutrients especially N. You may have excess watering and therefore excess nutrients. In addition if the soil is not draining well enough the excess N causes the roots to die and therefore speeds up the drying. The light comes in the end to burn the weak tip and de sides of the leaves. Dont worry flush with normal tap water for 2 weeks. Then restart with 1/2 the dosage of nutrients recommended for 3 weeks and then as you wish. If you can lift up the plant and the soil from the bucket you can add neutral soil at the bottom to quickly help the roots. Whats dry with remain dry. Bare in mind that there is hardly any problem if your soil is good and if you use very little nutrients. The vast majority of problems come from excess nutrients, we want to do too well. I only use very little nutrient and the soil from the garden is rich enough, thanks the permaculture principles i have applied. i wish you all the best with those rather beautiful plants.
