Oh Bro, considering the good general health of the leaves, these spots are very suggestive of droplet sunburn.

Could be dry areas in your root system if your using fabric planters.

Dark green leaves in meringue
Is my girl telling me that the flowering fertilizer is too nitrogen loaded? I´m using top bloom from top crop, feeding at 1.4-1.6 Ec, and since last week I started to follow the feed-water-water schedule. The NPK of this fertilizer is 4-8-8. Should I adjust the input EC?

Brown spots on tips of some leaves
4 leaves affected on only one plant. All plants are receiving same feeding and are from same clones. Based on photo and googling it looks awfully lot like P deficiency? I'm still in vegetation phase though. I'm feeding with Advanced Hydroponics Grow + Bloom + Micro based on chart

Do these look healthy? Thoughts? I'm new to hydro/growing
I have autos growing in a dwc system being fed half the regular amount of hydroguard, calmag, and grow/bloom. 1 plant is a week younger. The dark green plant looks like its leaves are clawing and has big brown spots on the leaves. The other has some brown dots and little yellow.

What’s appening to the little northern light auto?
so far I have only given her the rqs growtablets plus a break of plain water and given this reaction today I have also started to give her some advanced nutrients (MGB) is it just a delayed nutrient problem or should I worry?

Browning leaves sections of leaf surface discoloured
Day 18 leaf worries, browning areas, slightly metallic shine. I think from reading it might possibly be a phosphorus deficiency but I’m not certain so though I’d ask for advice. Thank you for your time and all answers are appreciated. Have a great day!

Some brown spots showing on the top sugar leaves. I suspect it is due to the cooling fan of the light blowing down hot air? I've adjusted the fans to blow air directly over the top of the main cola's and I increased the light distance.

End of Cycle or something to be afraid
Hi everyone, I think the brown leaves just reflect the end of cycle (WG started flushing 4 days ago, DSD33 today). I don't see signs of mold or something rotting, brown leaves do not detach, both plants show already some amber trichomes. What do you think?

What should I do for these brown spots? pH is ok, fertilizer is ok but didn't recover. Should I flush my plant with 6.5 pH water?
