I would say that is a tad bit of light burn if it’s only on the upper leaves of the plant, and maybe a bit to much nutrients if your seeing it all over the plant. But if it’s just a few leaves near the top then raise your light a bit maybe. Cheers💨

If your growing in soil like your diary says, your ph is set for soiless, not soil. 6.7 to 6.8 ph for flowering mode. 6.3 for veg mode. Cheers

Not Nutrient Burn
Well I'm stumped...ppm 600, pH 5.9...it certainly looks like nutrient burn but it can't be, tips yellow then darken and curl and get crispy. 3 days between pics in question and in diary. My only guess is that I upgraded from knockoff 100W LED to Mars Hydro 150W. Any ideas?

I noticed that I had what I thought was nute burn, I had only been feeding half strength canna A/B coco feed so I was confused and just thought that I had a sensitive strain on my hands ( ph5.8 I noticed my lights were on 24hrs! Would this cause the brown leaves?

Magnesium - Nutrient problem
Do I have Magnesium deficits or any other problem? I started to notice during the last week and it is progressing quickly. The last weeks, pH of drain water was low (between 5,5 and 5,8) but I could increase it until 6.1. Has anyone the same problem? Thanks!

Heat or deficiency? Or something else?
I'm noticing some sort of deficiency or toxicity. I need help on figuring it out. I water with distilled water, cal mag, and 1/2 strength bloom boosters. Ph @ 6.5. Could it be heat? It gets a little over 80 F. I have AC running, It's still cooler than outside in the sun though

K deficiency?
in the last pictures you can see what to me look like an early deficiency of K. Since she is in the first stages of flowering I would say that's the case, reading the literature online i noticed a lot of similarities, what do you think?

Cal/mag problem or heat issue?
A few leaves have some problem spots popping up here in week 6 (see pics). No nutes, PH’d water. FFOF/HF/Perlite mix for medium under 20 hours of light. I’m guessing either got too hot from being in 90F heat for an hour or needs cal/mag? Any advice from any veterans out there?

Nutrient & critter problems need 1-2weeks from harvest need advice
The plant is a couple weeks of harvest but has some issues. (Some kind of nutrient lockout or deficiency can't tell what tho, pH is fine at about 5.8) And I got these annoying critters that seem to live on the soil (but aren't touching the plant) Any ideas on what to do ? :/

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.

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.

Leaf tips show a nutritional Maybe Ca deficiency and nutrient flush timing
Leaf tips show a nutritional problem. Maybe Ca deficiency but adding extra of it since the beginning and or P excess. Thinking when time for nutrient flush. Maybe some degree of nutrient flush in combination with Ca? What do you think See week 14 for detailed question text
