I am having troubles still with what looks like a calcium deficiency and nute burn, the same problem I have been having. But the holes do not look like they are from nute burn, almost looks as if pests. But I am feeding them as should. Input? Pics will be provided above to see.

3rd note on light nute burn,
Defiantly have a solid mag deficiency too, look how purple your stems are
And the inter vienal lightning...
Your so close to being done, there is no fixing or correcting this round... keep notes, and andjust next Grow... 2 weeks ago you needed more mag and less over all ppm...
Best of luck

If not bugs as the others say- it may be wind burn ;) your ventilator should not blow directly on the plant- this is the cause for wind burn, happened to me- now i just direct the wind on the tent walls and no more holes in leaves

Hello I agree with Athos you can I. Fact see the nute burn on the tips of the serrations. It’s not a bad burn but it is there.

Check the leaves, but if you can't see bugs, I don't think you actually have them. What I can see is that you are over feeding and overwatering. There are many leaves with burnt edges.
1 gallon of water per day? that's way too much; how often are you feeding?
Let the soil dry before watering again, I use 3 gallon pots and give them half a gallon of water (2 liters) every 7 to 10 days and your feeding, 1.2 EC is too much for soil, unless you are at the peak of flowering, stay at 0,7 ot 0,8 and only 1 feeding every 7 to 10 days. I would flush the pots and not feed for at least 10 days

Hi mate,

If i'm honest, I'd say its not nutrient burn as that starts from the tips of the leaves and you'd definitely know about it so thats that cleared up. The older growth looks like it had minor nute burn but your new growth actually looks quiet good. Can always just back off the nutrients for the next 1-2 feedings and just use water to be sure as your plants look pretty green and vibrant already.
Secondly, the small holes you say your seeing could be something as little as adult flies or mites. You'll need a jewellers loupe to check the under side of your affected leaves as some pests are so small they are not visible to the eye on its own hence needing the loupe. If it is the case you can use Neem oil which you can spray on the affected areas and it will not harm your plant. Theres also something called 420 pest bully which is completely organic which you can also spray on your plants and will rid of pests. The other alternative would be to use natural predators such as lady bugs. Sorry about the essay! But hope this helps. Let me know how you get on. Good luck bud!

If you've got holes then I'd likely day bugs. Some bugs the miners lay their eggs and they live inside the plant so you cannot see them until the damage has been dealt.
You could always have light burn which can cause holes but not universally over the plant and you say you worked with the nutrients.
If you can spinosad spray that helps with miner bugs. Also a spray that has mostly water with a part of alcohol or bleach works well as a kill on contact and doesn't seem to damage the plant at all.
