This looks like it could be ph lockout . Try flushing your plant and see how she does

Hi! Check on "tobacco mosaic virus". The yellowish stains could be signs of it. Good luck!! :)

Kind of looks like very weird Potassium excess. Could be a form of PH lockout.

Are they still looking overwatered?
How are my babies looking? Watering now every 24h (0,5l) and I raised the pots so they no longer stand in the runoff (doh!). The calmag also arrived today so hopefully that will help my Green Gelato with the yellowing 🙌

Sugar Leaves Turning Yellow
Sugar leaves around top colas have started to turn yellow? No yellowing on any fan leaves. Plants are same distance to light and the environment has stayed constant. Only changed feeding cycle from alternating feeding/watering to feeding,feeding,watering (ppm still the same).

Mid flower flush
Hey guys :) Have you ever done mid-flower flushing and if yes, how did it work out? Gonna let the soil dry completely and then water nutes again. Could the pH being buffered to 7.10 (shit soil) be the reason for the yellowing leaves or does the plant need more or less of somethng

Help! Yellow fan leaves mostly at the base!
Help! My girls have shown some signs of cal mag deficiency and I’ve added it at 1ml/l per plant for about a week now.. But it’s not improving or is there something else? Tight for space and wondering if this is also due to not receiving enough light? New growth looks ok?

Nitrogen Deficiency?
Think I might have a Nitrogen Deficiency but just wanted to check and confirm with some of you? Leaves are slightly pale and yellow across the plant. I checked runoff Ph last week and it was 6.1 realised it can lockout some calcium so flushed with 6.7. Thanks

Just looking for some input on how you think the grow is going so far or any advice towards growing LSD25 and Mexican Airlines. I’ve noticed some of the lower fan leaves yellowing and drying up, I read that is normal going into flowering just hope it doesn’t spread up the plant

I can not take out of the tent to the darkness more than 4 at once and wanna hear your suggestions before I go with yellow sugar leaves or some amberish :D
I read something about harvesting immediately (not to crap the flower) when sugar leaves start to turn yellow and I have some! On the other hand, I saw some trusted videos that has some yellow sugar leaves. I want to ask you if you have any experience with this issue?

I need advice on what to do with this plant. I flushed her a bit and I think nutrient burining is not showing on new growth, what ppm should i feed her?
I watered only last week and mesaured runoff ppm and ph. Water was 350 ppm and 6 ph and runooff was 700ppm and 6.7 ph. Before when i fed her with 850 ppm runoff was 1500 ppm. I would continue to water only but there was a lot of yellow and pale leaves so gave her light dosage.

Leaves continue to get yellow and fall off. Plant dying, bud looks okay.
Still having issues with my plant. Leaves are getting more and more yellow and 2 have fallen off. Pretty far from harvest still for the leaves to be getting this yellow. Temps in tent are 18-22 c with leds 200w act wattage. Overwatered once but I doubt it would cause this. Ideas?
