Spots on leaves

[Giovannixxl]

Fruity pebbles OG
Coco noir/perlite
Ph -6.2
Ppm-1000-900
Technaflora recipe for success nutes
Under 2-1000watt led lights and 2 600 watt leds
4x4 grow tent

Im a first time grower
My question is what are these spots on the leaves is it a nute deficiency or is it light burn?
The feed schedule reccomended from the company is feed,water,water,feed.

I have read online it sounds like a deficiency but then again i also have saw light burn. I have the lights about 26 inches from the plants.
Im about to throw them into flower and wany to make sure everything is kosher. Also another question would be are they big enough to be thrown into flower they are about 26 inches tall.ive read they grown taller in flower.

6.2 is not the correct pH for coco. You should be in the hydro range and I think you will see better results adjusting to 5.8. This in my opinion is the cause of the yellowing at the top. You are also seeing the start of a magnesium deficiency and need to start supplementing with calmag or epsom, especially since you are in coco and running under LED.

They will double in height or even more once you make the switch to flower. Careful, you might already be running out of room vertically.

See i thought that too possibly so i doubled their dosage form 2.5 to 4-5 ml. And usually im at 5.8- 5.9 but that was just my last ph test. Do you think i should feed every day being im in coco or do as the nute manufacturer says?

Ah gotcha well then i prolly need to do the flip lol. Ive read youre supposed to do half bloom half veg nutes the first few times before switching over. Is this correct?

That is not the way I ever did it, but I never ran the nutrient system that you are using either. It is my belief that they are still in veg for at least 5 days of the flip and that it is not appropriate to give them bloom nutes until they are actually blooming. Don't believe everything you read either... there is a LOT of bad information being put out there, supposedly by experts. Check out the person giving you that advice.. see how many followers they have and what kind of gardens they produce. Question everything, test what you can. - Wee'zard
