Brown/Grey spots on the leaves
CreamOfTheCropstarted grow question 5y ago
Hey, I hope this is my last question for this grow :P I've noticed some brown/grey spots on the yellowing leaves, what could they be, deficiencies or sunburn? I'm still feeding the plant with nutes, but the next watering will be a flush, so I didn't expect discoloring before that

This late in the game.. it's kinda what you want to see.. the plant sucking out all those nutrients.. You want this.. Which is why you flush 2 weeks before harvest... Since your there at that point of flushing already.. I wouldn't worry about it much and just keep going man.. Plants look fat! Nice.. 👊

Plant issues... How long to harvest?Could someone please look at my (only) diary and give me an estimate on when harvest might be? I have microscope pictures up . I think I see cloudy trichomes with the possibility of a few amber. Maybe ready now? Not sure but hope to harvest before plant gets much worse. Thanks!

Is this really a potassium defiency? Any suggestions how to deal with it?Hey Guys, need your help please. It's FD 28 and the leaves of my three White Widows show some signs of a nutrient deficiency (at least my assumption).I'm growing in living soil w/o any additional fertilizer and watering with a 7:3 mix of osmose/tap water and 0,5 ml/l CalMag.

Leaf Yellowing?What is the yellowing in the last pic? The soil is top 20% Atami Cocos, bottom 80% store bought organic super soil. Watering tap water (EC 0.284/142 ppm), pH'd down from 7.9 to 6.5 with citric acid...
I think that's probably the problem? Any advice for the high pH tap water?

CalMag or something else?Discolored leaves at the bottom of a 3 week young auto flower, full feeding schedule in diary.
Was thinking Cal-mag deficiency, but after 4 days of running 2mL/L Cal-mag supplements it's still getting worse.
Could it be lack of phosphor, and will BioBizz FishMix/Grow be enough?

Soft hanging yellow leaves, some with brown spots in the middle. Deficiency, Nutrient Burn or what could cause this ?Hey guys, I got a problem with two of my 4 plants. They started to develop yellow droopy and soft leaves that start to fall off on their own.
I’m not sure if it’s a nutrient deficiency or blockout from ph or something else.
I watered them only with water ph 6.5.
