Flowering 5 Clones - Middle one looks Different?

I am flowering 5 clones of Train Wreck. It is currently half way through week 2 of flower. They have all been treated the same way. Mix of coco coir, worm castings, and organic fertilizer. Also apply compost tea every other week or so.

The middle plant, in particular, is showing signs of leaf discoloration. Pictures attached. One is of the full canopy, another is of the one in the middle, and the other pic is of one that appears fine.

I had a theory it could be from the light, but not sure. Also may be nitrogen deficiency. Any input is appreciated!!

Middle
Directly under light
Too close

I figured, thanks. Do you think it has time to recover if I move the light up/dim it?

No clue if that's it,but seems most likely the issues

What kind of light, how intense, and how far from the canopy?

I agree with Bob on the light, though it's possible additional feeding could help the plant keep up with the additional light. Just a thought.

its the Spider Farm SF-4000 (430 watt) light about 18 inches away at ~90%

18 inches seems fine to me. Any idea what your EC or TDS is?

You could carefully do a foliar feed on the fan leaves and see if it greens up. If so, maybe get more aggressive on the nutrient for that particular plant.

Not sure about TDS, but I have been watering with low PPM water.

I think I am going to top dress with worm castings and a little 4-4-4 fertilizer.

Just bizarre that I have treated all of the plants the same and this is the only one that has a real problem.

Thanks for your help!!

Like you said, you're treating them all the same, but one is getting more light than the others, so it will have different needs.

Oh, and PPM is just what TDS is measure in. Total Disolved Solids are measured in Parts Per Million. Be aware, different companies and countries calculate this differently. EC is an international standard, from which TDS is calculated.

Good luck!

But EC is calculated different too....lol
