Ph Wert beim gießen ? Du solltest in Erde immer einen wert von 6.0 - 7.0 haben da sonst ein „Nutrition Lock“ auftritt der verhindert das die pflanze nährstoffe aufnehmen kann auch wenn sie verfügbar sind.

I reckon it's light stress. You notice only the top of the plant is affected the most and in week 7/8 this is where it began. If it was nitrogen defeciency the lower leaves would be affected first. Could be an excess of nutes build up in the soil causing lockouts possibly because of indirect ph levels...

Most likely a molybdenum deficiency due to your PH a little low.

Plants didn't get any fertilizer during veg. I noticed deficiencies about 2 weeks ago, and added BioBizz Bio-Bloom, Top-Max and CalMag to next waterings.

Nutrient deficiency? If yes, what's the best course of action to salvage the situation?First time grower of 3 autos, at week 8, lower leaves started turning yellow, top leaves started to get smaller/develop brown spots 2 weeks ago. Is this a nutrient deficiency problem? Soil should have been fertilized for 3 months, but I'm thinking they burned through it.Leaves. Color - Pale

Slow growth yellow leaf edges what to do?Plant growing slowly (but still growing) with weak growth tips and yellow edges on leaves with interveinal chlorosis. Looks like overwatering / magnesium deficiency to me. I use a weighing scale to know when to water, but started the plant in 25L pot so this might have caused it.Leaves. Veins - yellow between
