You can see my setup here https://www.thcfarmer.com/threads/1st-grow-going-good.107556/
Long story short, I'm growing with FF OF in 3 gal fabric pots, under 600 w (roughly 900-1000 W equivelent) LED. 2 1/2 weeks into flower it's finally showing signs of flowering. I had to leave for 2 days after feeding and came home to this lol.
On the first plants I think I either have excess potassium or Cal/mag deficiency. Possibly light burn? near highest point of plant. Got browns spots and the edges are curling up.View attachment 907433View attachment 907434
Second plant. I don't know even know lol. More in the undergrowth. Yellow spots on a few leavesView attachment 907435View attachment 907436
Also both plants have some red stems on fan leaves.
Thanks for any input!
^ also noticed the new growth thin and twisting; more info would helpWhat is your PH and ppm at? I've seen similar issues with a sudden PH swing.
Looks a lot like mag deficiencies. Cal mag has the good balance plus easy way to add nitrogen that’s soluble. Or epsom salt, 1tsp to 2.5 gallon water , dissolve over night and feed it like watering , over time~3-4 days ensuring it’s just enough that the plant uses it and goes dry at soil, rinse and repeat for 3 dose cycles and let her recover, feed half rate nutrients and just let her grow and watch , drop humidity if in tent to 50% or less for the duration to help with the uptake and drying out of soil/ media
It’s hard to tell with those pics but the leaves chlorosis is indicting ca-fe-Mg line deficiencies, but I’m leaning to Mg as the burn or die off is spotty and from tip to blade mid. If the burn was the other way I’d tend to lean towards zinc-Mg-ca with ca being the culprit!But its on upper and newer middle leaves.
Also its been about 8 weeks in flower now and only the photoperiod QG is starting to form crystals, the "atuoflower" is not
