My 2nd grow ever. I am using soil in a 2x4 tent with two ViparSpectra xs2000s. I feed every other feeding usually 3-4 days between with the pictured nutrient. This started a couple weeks ago when I added the second light they started to taco and discolor so I now having each light at 50%. I keep my PH of water going in around 6.0-6.3. Have not checked my run off.

Water more. Drop your ph to between 5.8 and 6.5 (aim for 6.0).in veg you need higher nitrogen, I’d suggest new nutrients. Honestly jacks 321 is rly good pretty cheap for a huge amount there’s a rly good hydro version too. Or remo, house and gardens, or advanced nutrients. Idk what soil medium your in but try a good flowering dirt, living soil, perlite mix if your feeding less. More nitrogen at the start, higher phosphorus nearing the middle for bigger buds and better flowering and high potassium at the end. 1400ppm and add a flower booster. Flush two weeks and if you have soil add mollassis for bud flavour and microbial food. Better budd

I am not a soil guy but you couldn't have a more classic case of magnesium def in my opinion.

There may be plenty in the soil/feed so PH may be a factor blocking it.

If it turns out def, maybe because you have a beast LED, an Epsom salt foliar is a good remedy.

+1 for Jack's or Masterblend, you need a complete nutrient and what you're using is not that (Recommend you stay away from AN nutrients)


Btw you are not exactly in soil, its peat based therefore recommend a pH of 6.2 - 6.4



also recommend you do a slurry test and see what the pH of your medium is before you change too many things

Yeah man, that's a foreign language to me. I can only "read" the leaves haha But cannabis shows the same distinctive features when its sick no matter what medium you grow it in. Soil gurus gonna come through and help too so no worries mate.

I would have thought this is a nitrogen deficiency.

Nitrogen is going to yellow the entire leaf not just in between the veins that's how you tell the difference

N will also start from the very bottom of the plant and work its way up where magnesium can start in the middle and spread everywhere from there

Friend if you'd like to mince words that's up to you, I'm only trying to help

I pointed out that what you're using is not a complete fertilizer and you have at least a serious magnesium issue going on as mentioned above, and it's not going to stop until you get a complete fertilizer

also I told you what you medium was and what the pH should be; if you do a slurry test and would like more input post the results, either way best of luck.

On the left magnesium on the right nitrogen @amekins you notice the difference how when is more in between the veins? Also where it is and how shows up on the plant is a big indicator
