Interveinal chlorosis and dead spots on leaves, deficiency?
This started appearing about a week ago, after I watered until runoff with plain water. It's on a couple of leaves higher up both plants and seems to be progressing. I am feeding advanced nutrients Grow Micro and Bloom but have been using very low doses, like 1ml/L.

Phosphorus Issue?
Slurricane is having a phosphorus issue and not drinking water as fast after transplanting. I’ve been feeding cal mag every water and thinking it’s a root zone issue. Should I apply stop watering and apply a follar feed of 3 part general hydro nutrients?

IMPORTANT excess/deficiency? What's happening? Flowering is in danger
What's happening here? I think it could be Fe deficiency, Mn deficiency, S deficiency or maybe K excess. But I'm not sure about diagnostic and I think I can have more than one problem. Please help, I don't know how to solve it and I see how flowering is very slow and weak

Plant issues... How long to harvest?
Could someone please look at my (only) diary and give me an estimate on when harvest might be? I have microscope pictures up . I think I see cloudy trichomes with the possibility of a few amber. Maybe ready now? Not sure but hope to harvest before plant gets much worse. Thanks!

Leaves have some spots
My auto flower has started presenting some spots, it's on week 3. But I've seen these marks since the beginning of week 2, been measuring my ph and everything looks fine. Maybe the super soil is a bit too strong, and it has to get used to it? The lamp is 27 inches away.

Manchas en hoja
Hola! Aparecieron estas manchas en una hoja de una GG#4 de zamnesia en su quienta semana vegetativa. No es algo que me preocupe, ya que la planta tiene una apariencia sana y crece vigorosa. Pero nunca vi este tipo de manchas y me gustaría saber su posibles motivos. Un saludo!

Leaf damage/discolouration
The yellowing is from an earlier issue but now I'm noticing brown spots and the leaves curling up, some getting crispy-ish. I recently lowered the lights a few inches, knowing I was pushing the safe limits. Is this from the lights or is more likely a nutrient/pH imbalance?

What's the issue with this leaf?
Can anyone help identify the issue on this leaf. Dreamcatcher is the strain and I can tell they were a reveg. It was root bound and I thought it was an issue with the roots. After transplant outside and sprayed with my IPM the plant has recovered but still has a few like this?

5th Week Flowering Plant dying!
What is going on here? Started off as a Calcium deficiency so I upped the Cal/Mag, but the problem only seems to be getting worse. It only has 2-3 weeks left so I don't want to do anything too drastic. Any advice is appreciated!

Burned or finishing early?
So I'm very torn about what's going on with my Jack 47 Auto. There's part of me that feels I may have burned her, and another part that thinks she's just finishing early. I have details in the diary. Any insight about what I did "wrong" would be great!

Auto seedling discolouration
This discolouration has appeared on the leaves of one of my two gorilla glue autos, it has been there since the first true leaves which makes me think it could be genetic? I’d like to know if anyone has more information on the cause or if anything needs to be done about it.
