1st time grower - nute burn? Lockout? Potassium def? Light burn? HELP PLEASE
Experiencing some deficiencies/light burn/heat stress. Says SSH likes hot/moist climate. Plants are planted in FFOF Soil, fed them 15oz of nutes yesterday. Using advanced nutrient systems, see above. Light is a SF1000 LED meant for a 2x2 tent. Would that burn them hanging at 20”?

Yellowish spots ? Magnesium Deficiency ?
I noticed that on some leaves (not the new ones) there were 2-3 yellowish spots. And on a large leave, a point that turns brown. I thought about a small deficiency in Magnesium?

Help. After months of babysitting my "autoflowering dwarf" it's finally started flowering. In the last week though all the leaves have become mottled and yellow with burnt brown edges. What can I do to save her?

Suddenly, massive problems. Tried a lot already, nothing helped yet. Any ideas what I'm missing?
Hey guys, I've been growing for a few years now and something like this has never happened to me. Long story short, as soon as I move my plants from the veggie box into the flower box, they slowly start showing these symptoms (see pictures). The box worked fine for several grows

Yellowing leaves.
Accidentally resolved my original question instead of liking a suggestion and I cant change it 😅 Same issue still applies for now. I have been testing the PH going in but not out so I will try this and pass on my results after the next water 👍 Open to all observations.

Yellow Burned Bud Leaves. Purple Calyxes. Red Stigmas. Stunted?
As u go from top of canopy to bottom, the leaves get darker green and less burn. Lamp is at top of 3ft tent, 10 inch above canopy. Feed is at 1.3EC/6.1ph. Runoff EC climbs, then I FloraKleen flush about once a week. So is it just light burn? What you see? Is she stunted? Thx.

Yellowing dry leaves, late flower.
About 2 weeks from harvest time, the yellowing leaves which I put down to an early fade have become dry, brittle, curly and splotchy. Should I worry this late? Is it potassium defeciency, lockout? Should I begin flush? Add molasses?
