Hey,
So I germ'd these seeds on April 16th, sprouted on the 20th, vegged for nearly two months and flipped to 12/12 on June 8th, so they are now 49 days/7 weeks into flowering. This was the first plant I've ever grown, not once had a houseplant or anything, so this has been a HUGE learning experience. Here is all the info on my setup, then below I'll go into more detail about the issues I'm dealing with and I'll put some pics.
My setup:
All was going well until about a week or two ago when I started seeing some nute burn, which then turned into brown spotting, and various other issues. I posted on THCFarmer and was told to flush my plants because of possible salt buildup, so I ran 32 litres (8 gallons) of PH'd CalMag water through each plant, then followed up with that ~750PPM nute mix I mentioned above. I'm quite positive that this must have been an effective flush as I was removing gallons and gallons of clear run-off.
I also received advice to start watering twice daily instead of once, so I have been doing a half gallon for each plant twice a day, which gets me a generous amount of run-off, but doesn't seem to have done much other than help the fungus gnats multiply... At least I think they are fungus gnats, really worried they could be root aphids but I'm not sure what to do about it this late in flower, plus they don't seem to be causing any issues and no matter how hard I look I can't see any larvae crawling around in the coco.
I have also been seeing what looks like Nitrogen toxicity in a few of the plants for a long time, and no matter what I do with the nutes, that issue persists. A couple of the plants also hermied on me and have been seeded, but not super badly, I've only pulled off one set of nanners a few weeks ago, and then maybe 2 or 3 seeds last week and none since then, although it is very difficult for me to check underneath the canopy for any hiding in the lower area because I can't get under the SCROG net. I have also noticed that on my taller plants, the upper leaves are kind of curling in like a taco, and the tips are pointing up.
I am thinking it may be a potassium deficiency but I really don't know, it also looks like it could be light burn as the issues are more pronounced on the Gorilla Glue plants which stretched up much closer to the light, I can try dimming the light, but raising it will be quite difficult although it is possible. Lots of the leaves have also been feeling quite crispy.
Here are some pics and I have written all my questions below because I have some other random questions that I would love to have somebody more experienced answer for me! The darker fatter leaves are the GELAT.OG while the lighter, skinnier and more yellowish leaves are the GG#4.

So here are my questions!

My setup:
- 4 ft x 4ft tent
- 480w 3000K Quantum Board LED with 660nm UV red.
- 5 gal smart pots
- 100% Canna Coco
- Emerald Harvest 3 part base nutrients
- RH between 40 - 60% depending on weather and temps, I have a dehumidifier running 24/7
- Temps are almost always below 26 celsius (79F), and always above 16 celsius (60F).
- 2 fans running under canopy and one above.
- They are scrogged with the net about 12" above the pots.
- 4 plants, 2 GELAT.OG and 2 Gorilla Glue #4
- 8ml/gal Emerald Harvest Bloom (NPK 0-5-4)
- 3ml/gal Emerald Harvest Grow (NPK 2-1-6)
- 6ml/gal Emerald Harvest Micro (NPK 5-0-1)
- 4ml/gal Emerald Harvest CalMag (NPK 2-0-0)
- This mix comes to ~750PPM and I always PH between 5.8 and 6.2

So here are my questions!
- What do you think is causing the spotting/burnt tips/leaf symptoms?
- If it is light burn that is causing some of the symptoms, is it better to raise the light or dim the light?
- Is it too late to remove lower branches? There are lots of lower branches as I didn't do very much pruning before flipping, but now I just have a lot of under developed bitch buds, if I remove these now I'd probably just dry em out in the sun and smoke them.
- Do the buds look the right size for 49 days in Flower? They look very small compared to photos I've seen online of plants on the same day of flower.
- How long till harvest do you think, is it time for me to buy a microscope to check trichs?
- Any guess on the yield? Was hoping for a pound so that I don't have to buy buds again, as me and the wife are struggling with funds at the moment and we smoke about an ounce a week together...
