Problema con mi Runtz Muffin
Good morning, I have a problem with my leaves (I posted photos so you can see). I've seen that it could be a phosphorus deficiency. But it could also be a calcium and magnesium issue. Could someone help me with this? What should I do? Should I add a PK 13-14?

To feed or not to feed?
I burned these early but have been giving them straight 6.4-5 pH water for about the last 14 days should I continue with this or start gentle feed?

Sugar leaves affected- 6th week of flowering
If you have a look at the 7.5lt one, the sugar leaves affected by a deficiency, I was thinking of CAL... Considering I'm pretty close to the harvest time, shall I simply flush and switch to plain water to be on the safe side?

Ongoing pH issues
Watered at 6.5 pH and runoff was at 5.5. I am going to start watering at a higher pH today and continue measuring runoff. Should I stop feeding at this time? I have been feeding 1/2 dosage of Fox farms trio with every watering last 2 weeks. Is there likely soil build up to flush?

Color en las hojas
At the beginning of week 3 of flowering, the leaves are orange, we stopped fertilizing and the problem continues. It's a 10-liter pot, watered with a liter every 3 days, it's a Critical+ auto from Dinafem. I want to solve it but I don't know how, we're in week 4.

Runoffs are significantly below inputs-Do I have a problem?
Runoff continues to be a mystery. When watering I continue to get significantly less Ph and PPM (4.8 ph and 109 ppm) than my inputs (6.2 ph and 155 ppm) but the plant looks healthy. I have no idea what is going on or if its even a problem. Should I be worried and what can I do?

Nutrient Help possibly needed
For my first grow I have kept things fairly simple. I had issues with my soil PH which stopped nutrient uptake but seems to have now resolved that for the most part. Are there any other nutes that are recommended to help bud production or am I ok with what I have now? Thanks

Pin the tail on the deficiency
Some yellowing that developed on Gelato Auto in the last coupla days....my guess is nitrogen deficiency since feeding has been light throughout growth but I'm still new to the game and would love to hear from some more seasoned growers

Need help identifying the deficiency here
I just started seeing some kind of deficiency on the lower leaves of my plant that's still pretty young. Can someone please help identify? Just tested the PH and it's at 6.4. I'm not seeing any spots on new leaves. Do I ride this out? Do a flush? Appreciate any advice!

Please help identify the cause, interveinal chlorosis since 2 weeks old, no necrosis so far. These two plants are 26 days old. Do they look stunned?
Is this magnesium def since it's going from the bottom? Is it possible the first signs started to show when they were just 2 weeks old? Or is this iron? Or is it smth else? Calmag given two days ago. Pistils show already. I water with ph6.2 but no runoff yet to know the soil ph.
