Burning Edges/Yellowing and Drooping?
The yellowing has gotten worse and I'm noticing slightly burnt tips/edges and some droop. Could this be burn/deficiency or over/underwatering? A combination? Is there anything I can do to fix this early or is it just a matter of giving them some time and less nutrients? Thanks!

Is this a nitrogen deficiency? It's happening just on the 3 bladed leaves of the plant on the left. The plants look overall healthy, at least I think

Burn leaves? Yellow leaves? BIg problem? (AUTOFLOWERS)
I had a problem with a lack of magnesium in the larger plant and I applied a little with a sprayer directly on the leaves, I got confused, I sneezed once on the leaves of the smaller seedling. Can I do something to resolve it? I even thought the LED was too close and I raised it

Bottom leaves yellowing.
Worried about bottom leaves yellowing & drying. Third ever grow, never managed to get >5g yield so not very experienced but learning as I go. Not sure if overwatering or underwatering or a def / lockout, haven't abused her as far as I can tell (nute od, etc). Any help welcome :D

If this was yours, how would you proceed?
Going into week 6. I just clipped the bad leaves that show in the picture and will be switching to the growing stage. I plan to do the 36 hours of darkness first. Already changed the water and it has the bloom solution instead of the grow solution. What would you do now?

Leaves bright green
So I have ruled out the fact that this is not a ph problem, have been properly watering at a consistent ph of 6.5, tested the run off today and it's at a pH of 6.4, also there is purple stems and the main stock has purple running through it as well?!?! Is this lack of pk? ca/mg?

Yellow blemishes
1 week old seedling is starting to develop yellow blemishes on initial leaves. Soil is biobizz lightmix, PH 6.2 from bottled water with no nutes, 150w led light is at 50% and 25-30cm distance. Is it a cal-mag deficiency, light burn, genetics, or just too soon to worry?

Is the slight yellowing ad curling of these leaves ok or indicative of something?
Curling and yellowing of leaves in a few instances, both near the top and bottom of the plant, with no noticeable discoloration on the branches in between. I'm feeding it 1/4 strength Grow Big (2Cups) and 1/4 strength CalMag (1Cup) when I water every 3rd day. Ph runoff 6.8.

About plants ..
For those who have dealt with nitrogen deficiency, after correcting it, did the affected leaves regain their color, or did they stay the same while only overall plant health improved?

I'm still trying to raise my soils pH, I'm using Olympus up which has lime, should I give a higher dose or jus pH water till pH runoff goes up?
If I use nectar for the gods Olympus up which has lime in it and I'm having low soil pH probs, should I use more Olympus up and adjust my pH and would that help raise my soils pH? Or should I jus use pH water until my pH runoff is where I want it? Advice greatly appreciated.

Strange yellowing leaf in flowering
What's wrong with my plant? New growth is yellow at the base of the leaves. They've been fed more than usual so cutting back on nutes and I've given them plain water today.
