started grow question 6y ago
What can this be? It happened in 1 day. Is plant asking for nuts? I added only water for 4 days because i was afraid of been giving to much nutrients. Could be a pH problem?

Nute Burn Plan. Lower light to 24 inches and turn on bloom switch. Flush soil with 8 litres of water (PH 6.5) per pot. Questions: will increasing the intensity of light increase plants ability to absorb nutrients, or simply stress them more? Is 8L water/ 10L pot enough to flush?

Yellow leaves at the bottom
Some few leaves, two older and two new ones, turned a little yellow. All of them on the bottom of the plant. I don't know if this is a normal development or perhaps Na deficiency? It's my first grow, so I don't have experience. Help would be appreciated.

Yellow leaves and spots
Noticed some leaves growing yellow at the bottom of the plant, a few days ago, added biobizz bloom as I hadn't used any fertiliser yet. Today I noticed the spots on 1 of the leaves, veins in the middle have what looks like rust. Any ideas?

Is this definitely CalMag deficiency? Check diary for video.
Before I go to over the top with the CalMag in a stupid attempt to nurse my plants back to health I just want to know for certain what it is. The leaves are clawing, bronze spots everywhere but the smallest of the 3 doesn't seem to be suffering as much.. what is it?!

I don't think this is nute burn...
So I thought I had a case of mild nute burn but I haven't given the plants any Bloom or Calmag since last Friday, only water so I'm wondering if this is a nute burn issue now. Could it be my PH? Last I tested my run off it was at about 6.65. What's causing this?

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?

So this is my first time growing with using BioThrive grow, bloom, calmag bottle ferts. Would greatly appreciate any feedback on improvements, those 2-3 leaves with yellow spots seem concerning. On 'honest' scale of 1 to 10, how are my buds looking for week 6 in flowering?

Yellow sugar leaves
I am waiting for a low-THC strain to develop amber trichomes and I found two buds with these yellow sugar leaves. There is no bud rot, should I wait longer to harvest? Also, do CBD strains develop amber trichomes, or should I harvest now? Additional details available in growdiary
