Yellow edges
Bimbadabang
started grow question 6y ago
I had just dealt with a calmag deficiency but adding biobizz calmag, but now the leaves are starting to yellow on the edges. Is it still a calcium or magnesium problem, or is it something else?

Should I cut the first leaves to maximize the grow
Hello everyone A friend told my that I should cut the first leaves of my plants (the first that came out from the plants, not the cotyledons) What do you think about this idea ? And can this really maximize the size of the future buds ? Thank you for your responses ! :)

continuing nute burn or deficiency now? biobizz lightmix +organic nutes | runoffs EC 1.8-2.5 | PH 6.3 | DLI 45
cca 10d ago, I found early signs of overfertilization. I reduced nutes, but yellowing continued. After a flush 2d ago, things got worse (now also edges browning). I now suspect potassium deficiency or still nute burn. Next watering is near—should I flush again or feed properly?

Phosphorus deficiency?
I think this is a phosphorus deficiency. I thought it was because I slightly overwatered the plant. I gave the plant 1.5l water without nutrients then waited 4 days. Then 1.5l water with nutrients will also wait 4 days. The problem seems to get worse. Anyone any advise?

Whats wrong with the plant? Is it Male or Female?
Hey guys, its day 23 I noticed this yellow spot on plant #1, overall the plant looks healthy, is it normal for it to turn that color at this stage? Ph 6.10 Ppm 205 Feeding only 1/3 of the recommended nutrients (CalMag, Pure Blend Pro Grow) Is it to early to detect its gender?

Weird leave discolouration
Not sure what this weird discolouration is from. I panicked and cut the bud off in case it was a disease or something. No other places on the plant have similar thing happening. Any ideas?
