Just saw in your diary that this problem existed for longer, you are feeding frequently and you mentioned possible overfeeding at one point. Maybe your potassium intake is being "blocked" from too high amounts of N / P / Ca &/or Mg. In this case you could consider to try flushing your soil if possible to remove built up salts.

Looks like a potassium deficiency to me. Flowering plants have a higher demand for K than vegetative plants.

problems with low leaves in the lower part of the plant some leaves are yellowing, others are drying out and even detaching. can it be due to the fact that since flushing (a week ago) I have not given anything to the plant anymore? I hope this does not compromise flowering

Browning of leaves, heat burn or pests?Plants are showing signs of browning, and other weirds leaf markings, kind of grey-ish not too pronounced. It's been very hot and sunny here for 5 days, temps reaching above 37°. I left them in the sun during this period, is it heat stress? Otherwise growing nicely.

Late Flowering Stage Deficiency or Nutrient Burn I'm not sure if this is nutrient burn or some sort of deficiency. Burnt tips were from possible previous nutrient burn, but now I'm seeing Brown spots and some discoloration. Please check my week to see full details.
