Yellowish Spots on Fan Leaves
Cali_Grown_420started grow question 4 years ago
The fan leaves on one of my plants are getting yellowish spots. I noticed it yesterday and checked the pH and I was at 5.0. I corrected it to 6.0 and 24 hrs later still 6.0 but some of the larger leaves are starting to show yellowish spots as well?

Hey buddy,I think that yellow spots mean Calcium deficiency.Cal and Mag are not available much in lower pH range.As I can see you are using pH perfect nute, I think you should change your res.

Hey Growmie,
It looks like your ph being so low caused a nutrient lockout that's effecting the intake of your nitrogen, magnesium, and iron, nutrient imbalances of these 3 can cause yellowish spots to appear. If you've corrected the issue no more leaves should be affected, those affected may not recover.
Hopefully, this was helpful and remember ..."Happy Growing" and "Free your mind one puff at a time".

Yellow Leaf Tips with Brown Spots – What Could This Be?One of my plants has yellowing tips on some of its leaves, and there are also brown spots forming on these yellow areas.
Any ideas on what could be causing this? Could it be a nutrient issue, or is it maybe related to pests or environmental factors?

Slight lightburn?First pair leaves on left plant turn slightly lighter, first sign of yellowing a bit. Also I think they are a bit in a V/praying shape.
2 full weeks old under 75% of 200W leds about +-45cm. Should I dim them a bit more/hang higher?
Other suggestions maybe?

Yellow blemishes1 week old seedling is starting to develop yellow blemishes on initial leaves. Soil is biobizz lightmix, PH 6.2 from bottled water with no nutes, 150w led light is at 50% and 25-30cm distance. Is it a cal-mag deficiency, light burn, genetics, or just too soon to worry?

Is this Stating something or is it paranoyaI had a few leaves that were turning yellow, but they are lower leaves that are slightly yellowish on the outside, generally the plant has become a little lighter since it started flowering.
Am I worrying too much?

Should I cut off yellow leaves?Bulldog cookies, 5-6 weeks in flowering. The leaves started yellowing, not fast like a disease or something. I'm thinking about cutting them off. should I? Would it be better for bud development, or in this flowering stage is would be too much stress?

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
