Could it be magnesium deficiency or something else? I'm already using biobizz cal-mag with the suggested dose. Tx

I don't think it's magnesium problem. Also not a calcium problem. Is it a lower leaf and has your pH been on point.

Just had a look at your diary. Have you got plenty of drainage because you plant looks a little over watered. Make sure you get run off when u water.

Heatlight stress?
Can someone tell, are these brownish tips the sign of the heat stress or something else? And how bad is that for the plant's not so distant future? She grows indoors. Peak DLI was almost 60 but very briefly about one night. Now it's dimmed to 40dli/~600ppfd/ 20/4 schedule.

Foxtailing Yellow Leaves White Trichomes - WHAT HAVEW I DONE?!
Hi! It's my first grow and I thought I was Doing alright. After I've bought a tent, seems like things got worse. My flower is an auto in week 13.4 (supposed to take 9-10weeks) and I'm flushing since about 10 days. Still the trichomes are pretty clear. What should I do?

Thoughts on leaf symptoms? The other plant in tent is doing same thing,but plant in other tent getting similar feed not. see diaries for more pictures
K deficiency? Hard to believe that can happen in 65-gallon pots.Are getting big though.New growth tips looked yellow,hit them with water-soluble K and the new growth edges seemed get green.Some toco-ing, humidity is kinda high. Too intense light(800 ppfd), not enough C02 maybe?

2 autos with crispy feeling sad looking leaves, how can I help them? (more info in diary pl & crit)
2 of my autos have been growing leaves that feel crispy and look deformed. I have been watering when the top 5 cm of the soil dries, but I fear maybe I fed them too much nutrients. The temp has also been on the high side (30C 80F). What could be wrong and what can I do for them?

Leggy Seedling Recovery attempt
Plant got leggy. Lowered 100watt vivosun grow system light. DLI is now at 40 with 20hr on cycles. Plant dropped into final pot so soil could support weak thin stem. Watered recently and leaves got more yellow. On day 4 after recovery attempt. Any advice? PH 6.2-6.5.

Leaf Issues
Hey all, my almost 5 week old Moby dick auto flower is starting to show some issues in the first week of flower. She got a dose of Veggie nutes 5 days ago, and a little bit of Bloom yesterday trying to fix it. Temps have been high and humidity low, would that cause this?

Lower leaves too pale or yellowing?
I am noticing the lower leaves of my Royal Critical Automatic to be much more pale green than the top of the plant. Is this a nutrient/light/watering/lst stress problem if at all? First Grow. Started balcony, moved to tent D23. SF-1000 light, 100% at ~ 55cm from canopy.

Yellow on leaves
Day 13 leaves started to look yellow / dull on tips hasn't seemed to improve 2 days later, it is the auto soil premix I'm guessing the roots are getting close the soil and nutes kicking in or does this look like another issue?

White spots on a few leaves
Any idea what these whitish yellow spots are? They appeared overnight. I'm growing in ffof with perlite and ewc. No nutes added yet, just bush doctor cal mag at half dose 3 days ago with great white, recharge, and photosynthesis Plus which was the last watering of 1.2 liters.

Advise to flush or feed in Veg
Does this is look like a nute burn, deficiency, or ph problem? The two plants that are growing a tad taller have had yellowing tips some curling downward. Don’t want to overreact and cause it to worsen, they’re looking healthy otherwise. Any advise whether to flush or feed?

Excess or Defiancy?
Some leaves from the top of my biggest plant, Frisian Dew, turn yellow and brown. The others don't show this behavior. The plant is in week 22 and still needs approx. 4-6 weeks until harvest. The plant pot is fully rooted up to the surface.

Should I do full flush til runoff is 300ppm?
So, it is obviously a deficiency, which probably caused by a lockout. Will the full flush solve it? Yesterday I fed her a full dose of flowering nutes. Including K. It didn't change much. Lower fan leaves continue to go yellow. Today 3L water, pH:6.2, runoff:0.6l, ppm:1450, Ph6.0

Is this some sort of immobile nutrient deficiency or excess? Could this be caused by heat and light stress? She is 80cm tall and almost touches the lights in the tent. I'm usually suffering from Calmag and Nitrogen issues and haven't yet experienced yellowing from the top. Thanks
