Think you are looking at a calcium deficiency there, maybe slight overwatering hard to say. Add some calmag to your next feed and keep the ec up.

Just looking for some input on how you think the grow is going so far or any advice towards growing LSD25 and Mexican Airlines. I’ve noticed some of the lower fan leaves yellowing and drying up, I read that is normal going into flowering just hope it doesn’t spread up the plant

1st plant. Seems stunned and yellowish with black dots tips. Can anyone give a hint?
Hey, guys! How are you doing? This is my first plant. It is 4weeks old, planted on cocó-perlite mix. I find it growing too slow based on other diaries, and it is starting to show these yellow with black dots tips. Anyone can tell me what’s going on?

Identifying the cause of stress
Does anyone know what I’m seeing with the leaves in these photos? The closest I’ve been able to guess from online resources is maybe sulfur deficiency, but to my eye it doesn’t seem to quite fit any of the broad categories. Perhaps just general under-fertilization?

Yellow leaf tips and edges
Yellow leaf tips and margins… what do you think? Nute burn? Light stress? Cold stress? Will this eventually resolve if I leave it alone and let it work itself out? (Which is what I’m inclined to do) Should I flush my plants or try some other intervention?

Is this yellowing normal? Probably because of LST?
I am growing my plant with LST and some of the lower fan leaves have been moved down in the shadow. Is this the reason why those leaves are getting yellow and dry? All the rest of the leaves look very green and healthy by the way.
