hey bud-- Hmmm, how close were the lights to begin with? Was it at near or full power?....typically about 18" or more, wattage depending, for seedlings which want less intense light,... But I'm not so sure this is light damage, given how the MG is reacting, and it's not likely a defc. issue-- too soon, and she still has those cotly's to draw from,... she looks to be keeping pace with the MG too,... could be just a wonky seedling,... lets see if she colors up after this lighting change, and watch her growth speed,... might want to double check soil pH too,...hey bud-- Hmmm, how close were the lights to begin with?

The LED was initially 30 cm away and was set to 60W which is almost at full power in the vegetative mode of max 80W and 150W in flower mode. The med gom did not experience this intense LED light for so long because it popped out of the ground 2 days after the red poison and I have turned down the light intensity as soon as I saw that red poison's first pair of leaves started to turn yellow. First I also thought that it might be a PH issue but the poison's leaves were perfectly green and healthy for the first 2 days and I only saturated the pots with water a few days before planting the seeds and have not watered them again. Unfortunately I do not have the soil probe to check the soil PH accurately.Thanks mate, I really hope that she's going to be fine again. However if she doesn't recover in a week then I think I will have to replace her with a new seedling. I just want a healthy and colourful red poison plantThere is no problem there. Back off the LED to 18" for now and call it a day. The seedling will be just fine. Doubt it was the light anyways.
