Which deficiency?
So I've asked before if it was a magnesium deficiency on the GC and got confirmation based on the early pic, but now I'm starting to wonder if it is? Buds don't seem to fatten up either. Maybe calcium or potassium? Lights too strong? Overfed? Shouldn't have given Vega just flower

Damage?
Hi! My plants look damaged on the leaves, as well the tips are slightly burned. A few days ago I gave calcium and Epsom salt, I don’t know what’s wrong with them, please help me! Moreover I recognised yesterday that the light was turned on 24/0 by mistake, I changed that now.

High Leaves stress in the last week!! PLS help!
Hi everyone! First indoor grow with autoflowers. Everything was fine until week 6, even after topping, but now in mid-flower the leaves show clear stress. I thought it was CalMag, but supplements haven’t helped. Any advice? I don’t want to lose my first harvest.

Yellow edges
I had just dealt with a calmag deficiency but adding biobizz calmag, but now the leaves are starting to yellow on the edges. Is it still a calcium or magnesium problem, or is it something else?

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?

So- largest plant (photos above) yellowing lower fan leaves, overall light green colour on the entire plant. Possible Nitrogen deficiency? Otherwise she is healthy, budding up well and looks great. Any thoughts from the GD community? Thx as always!

Phosphorus? Potassium? CalMag? What is going on here?
So in week 8 after flushing with EC 0.4 and giving extra PK 13/14 afterwards (EC 1.9) there are still problems occurring. I personally think it’s a deficiency of potassium and phosphorus. Can anybody give me some advice or tell me how to fix it? Thanks!

Brown Spot Assistance, Please
Noticing these brown spots on the leaves are getting worse. We started Fox Farm Tiger Bloom about two weeks ago and my thought would have been that would have helped. Would appreciate any insight into possible cause and level of concern. It’s flowering really well. Thanks!

Weird discoloration, what is the issue?
I've noticed this discoloration on a leaf. It has slowly got larger over time. Any idea what it is? Will it ruin my grow? I'm pretty sure its not over/under feeding because its only on this leaf. Any ideas?
