Neon Yellow Tips?
Lemon Yellow Tips. Genetics, right? I have 4 in RDWC others don't show. Doesn't seem to be a problem. Never browns or curls. She seems happy and has done it since early childhood. I am just curious, as to what is, for future grows? Also, it may turn into a problem later?

Wind burn or over water?
The leaves on my plants are getting a little crooked. Look at the last photos in week 3 to see. My fan is in low pointing away from the plants. The little guys move around a little bit, but I’m worried it’s too much. Or am I overwatering? If look, you’ll see I don’t wander much.

C02 exhaust bag
Hi. I wanted to know if adding a CO2 exhaust bag in a small grow tent (60x60cm) is effective for overall growth? I'm European and most off my pairs said it was useless but the topics dated from 2010s and I couldn't find current definitive argument so... here I am.

Necrotic spots
The last day or two I’ve had a bunch of necrotic spots pop up on the lower 3 sets of fan leaves. She is at node #5 now and starting to put out pistils. Is this phosphorus deficiency? I changed the res as it was close to a week anyways. Thanks all for the help. Happy Growing!

Suspected Calcium Def?
Think this might be the start of a calcium deficiency. Only on two of the older leaves and in similar spots on the leaves. These leaves may have also had some water on them after the last watering. Tried to remove it as best I could. Any thoughts?
