Woran könnte es liegen ?

started grow question 6y ago
Nutrient-poor or too little water? It hasn't rained a drop at all in the last 2 weeks, and I only water rarely since the soil is actually moist at about 30 cm deep. With this weather, I'm not sure.

Brown tips and edges, but not on all plants.
2 out of 3 Kratky plants are showing some crispy brown at the tips and edges. Would I be seeing nute burn at 550-750 ppm? Why only 2 plants? Why only the Kratky but not the DWC? (Same strain.) (I am actually using GH FloraDuo A and B) Thank you!

9 days old seedling suffered from a heat/light burn
Will the seedling recover from its heat/light burn ? When going outdoors, do you usually place your seedlings under the direct sunlight ? Current temp in my location (22°C day/15°C night) Thanks in advance !

Light, nute, wind or heat burn?
Im getting some browning on the serrated edges of the leaves, moreso on the upper fan leaves, but not on the sugar leaves, with some cupping of the upper leaves and the ones directly under the light are getting a lighter color overall. Any guesses? Light, nutes, wind or heat?

Can anyone help identify this tox/deficiency?
Week 6 I noticed that all the new growth has burnt tips I assumed this was a bit of a nitrogen toxicity problem since the leaves were all a nice dark green, no pale leaves were popping up. Also held back on feeds for a few weeks. Other forums said it’s normal but want to be sure.

Deficiency or excess? I haven't done the pruning yet because I'm afraid the girls aren't 100% healthy. But they seem happy.
