Help me diagnose this color on my leaves. I don’t if it’s something to be concerned about I just don’t want it to get worse. Overall I think they look great. What do you think?

I believe you are experiencing ph fluctuations. I'd calibrate your ph pen if you use one, if not I would recommend one.

They look ok. I would say 2 things, too much nitrogen and not enough pk, correct these and you should be fine going forward

Is this heat light burn? HPS 600w at 20cmIs this light heat burn?? These are all buds at the top of the canopy and they are the ones nearer to the lights. I have 2x600w HPS, one with a cooltube and the other just with the wing. The possibly burnt buds are the ones under the wing (just 20 cm).Leaves. Edges burnt

I think underwatering combined with the light being close has caused my issue. However older leaves have also dried up and died (but staying green).
The way the leaf looks with yellowing though, and because a couple of leaf stems are turning reddish, maybe it's K deficiency?Week 6

What deficiency is this?Earlier, I added Epsom salts to fix purple stems, I’m pretty sure I over did it and I think this is a potassium deficiency but I’m not sure. I was being cheap and didn’t change res b4 moving over. Now that they moved tents, seems to be getting worse. How do I fix fast!? Pix in di6y ago

Light stress?? Wilting leaves, shrivelled and burnt edges. See pics in last week.Any idea what’s going on? Leaves are shriveled and wilting, as well as some burning at the edges? I’m guessing this is from light burn/stress as I’ve only watered and used very very little nuts so far. Lights were at 22 but now at 30. Temp is 24 w lights on, 55 humidity. C pics.5y ago
