started grow question 4y ago
What is causing this and can it be fixed? I was giving her some nutrients not a lot, and I haven’t given her any in about a week. Only water now and it started popping up after 4th feeding.

If you'd please look at the pictures with 'question' stated below them? This is actually the biggest bud, only it is showing these strange edges. There is (for now) no budrot, i checked. The leaves are firmly attached. What should i do, harvest it? The other buds don't show this.

My plant has mass nutrient burn on most of the leaves, I've flushed the roots. Is there anything else that can be done to help recovery or is it to late in flower. Also should I remove all the effected leaves or will they still convert energy for the plant? Thanks

I probably have spider mites on my plant. Yesterday I sprayed it with Maag oil. Today I bought an organic product and sprayed it on the plant. Are the discolourations on the plant caused by the mites or burns due to increased light from the drops? Or a lack of nutrients?

Yellowing/purpling leaf tips outdoors
Im experiencing yellowing/purpling on upper canopy leaftips of my outdoor organic cannabis plant in week 2 flower. I'm feeding via compost+dry amendments so over/underfeeding is unlikely. What might be the cause? nutrient lockout? Relatively low temperature (57-75F)? pests?

Yellow Burned Bud Leaves. Purple Calyxes. Red Stigmas. Stunted?
As u go from top of canopy to bottom, the leaves get darker green and less burn. Lamp is at top of 3ft tent, 10 inch above canopy. Feed is at 1.3EC/6.1ph. Runoff EC climbs, then I FloraKleen flush about once a week. So is it just light burn? What you see? Is she stunted? Thx.

What could be causing this?
I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far. I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout. Anything else it could be??

Biological Cal/Mag alternative? It appears the cal/mag from BAC is mineral feeding, is that correct?
Starting to see what looks like a deficiency of Cal/Mag. I'm trying completely biological and I can see the Cal/Mag under the mineral nutrients tab from B.A.C. Is there a biological alternative?

Nitrogen Deficiency or Light Burn.
How can you differentiate between a nitrogen deficiency or too much light in an organic grow when only the tips of bottom leaves are affected? I am using 60 led lights on one plant (Wakyme).

Guess on what this is?
Unsure what this issue might be. PH seems in check going in and out. Getting mainly Fox Farms nutrients - got very weak doses of B-52 and CalMag a week or two ago. The other two plants are fine.

Please look at last picture - there is an area of crispy brown on the lowest leaves of the Red Diesel. I'm thinking it's a little bit of light burn, but am not sure. Any thoughts from any of the experts?

Leaf Edges discoloured
I stopped nutrients a week ago. The soil is SoHum living soil though. Only gave CALMAG and BioBloom as i noticed a likely N deficiency. Today i noticed the tips are discoloured. Should i be concerned? Today they’ve been in flower for 7 weeks. Ill give them roughly 2 more weeks.

Chewed up leaves
Wondering if I should be concerned? They have just entered flowering, I have noticed a few leaves bearing this issue. I use ties which have ripped some leaves due to me not being gentle, and I spray a mild cannacure solition regularly.
