It is a magnesium deficiency. If growing in anything with coco coir in mix you always need cal mag supplements. Nor sure if you are. It is magnesium deficiency the leaves won't repair, but will stop the spread. So even some epsom salt would help your issue. Good luck and happy growing 🌱

Hi,
That looks like micro nutrient deficiency.
Magnesium or zinc deficiency. Many deficiencies happen after some stressful event and may blow over if you keep feeding it normaly and the the stress element disappears.
Dunno about Biobizz but most Calmag products have trace elements like iron and zinc in it too so that might be a good option.
Good luck.

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?

Leggy Seedling Recovery attemptPlant 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 IssuesHey 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?

Yellow on leavesDay 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?

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?

White spots on a few leavesAny 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 VegDoes 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?

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

Buon giorno weed doctors, did anyone have similar uniform chlorosis at the top or maybe knows what's up? What could be the reason and the solution? ThIs 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
