Can anyone tell me what deficiency is in that pict...
CRiSPrGrowanswered grow question 5 years ago
it s magnesium deficiency but not because of magnesium, because of the lights being too close. you can see that from the too short inter node spacing in the plant and the light burn on the leaves. If you move your light a bit higher, the temp will go down and hopefully the plant will recover. Hope this helps !

WHY?? Still looks like Calcium Deficiency?? HELP!!!Can Someone Please tell me what is going on here? I have a detailed diary if you have any thoughts on why it still looks like a Calcium Deficiency. Plant looks healthy except this. First time for coco (bagged & prebuffered), grow dots, and wick bases so I am at a loss.

Calcium Deficiency???So this is a Calcium Deficiency right? Noticing on top leaves. Not bad yet but want to stop it before it starts as this grow has been my best so far. I have been using CalMag every water but I did lower the dose for a few days as I was told I was using too much for flower.

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…

Progressive yellowing on older fan leaves ~F14-F35Hi, past two weeks or so I've been noticing progressive chlorosis and eventually some necrosis starting from the edges of the leaves and working inwards.
Photos of this can be found in Week 18 Flower denoted by "For grow question #x 12/1"
Humidity low, could be related?

Blotches on Haze Auto leaves (End of Week 8) - Diagnosis?Could someone look at the last few images of my Haze? Is this a deficiency? What should I do at this late stage? Otherwise it seems okay, other three Autos are doing great. Block would look different? Very crowded tent. Fairly warm 25-30c. Humid 55%. Feeds 600ppm. Cheers!

Just to confirm, this looks like nute burn, doesn't it?Burnt edges, tips curled up, canoeing. I've been having trouble balancing airflow and heat in such a small tent, and as a result the tent is on average about 28 degrees celcius daytime and the plants still get a lot of wind. Looking for whatever advice you can give! :)

Started LST but now plants look a bit sick?I attempted to do LST but I think I've maybe started too early as some of the leafs started to wilt kinda bad afterwards. Was careful not to break anything. Edges are curling and have discolored. I have a feeling they're a bit short too?

Day 46 NL Auto: Multiple Leaf Problems Developing after Possible Nute Lock and 2x Flushing — Should I feed again @ lower TDS? What’s wrong?Hi growmies!
Wks 3-5: overfed 3 plants
Wk 6: TDS after plain h20 1800-2300ppm; 2 flushes w/ gallon h20/plant
Wk 7: TDS readings 500-800pp, but 1 plant showing multiple types of leaf problems
I thought I fixed it, but now I don’t know what’s up or what to do? Thoughts?
