Yellowing of undergrowth within 2nd week of veg
CoastalEisenbergstarted grow question 3 years ago
What is causing my plants to yellow in the lower growth? Using Coast of Maine soil so shouldn’t need top feed for another couple of weeks. I’ve tried a mixture of liquid calcium (organic) and epsom salt to provide cal mag organically. Any recommendations?

Def looks like mag. If you’re confident it’s getting a good amount now, are you sure pH is in range? Cal and mag i believe taper off uptake when you get below 6

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 growsLeaves. Edges burnt

Seedling Light-burn or ToxicityHi growers!
Is this Light Burn, or nutrient toxicity from nutrient dense soil?
2 Mars Hydro TS600 lights at 27" from seedling.
PH 6.3 misting soil - RH is 75-80%. - Temp is 77F
No light meter, so I estimate PPFD is in acceptable range despite using 2 lights in 2x2 tent.Week 1

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…Leaves. Color - Yellow

The stem is awfully purple, watering/feeding is where I struggle. 1st pic - 4/21 and 2nd pic - today(4/24). Seems to have escalated over the last few days. Do-si-do auto about 10 weeks.Leaves.
