Purple seedlings

C

Covid420

Banned
Just transplanted 24 hours ago. Were purple stalks before in rapid rooters as well. Leaves looking a little purple too and the cotyledon leaves wanna curl down and inwards. Watering with ph corrected 0 ppm RO water to 6.5 ph. Temperature with light on (t5 4x2 8 bulb) only 4 bulbs active is between 27-29 °C. I have no real way to cool down without sacrificing humidity. RH 65%-70% 7500-8000 lux reading. Light 24" distance. First pic is white widow and second is green crack.

I was thinking a heat issue. First set of leaves seem healthy.

I'm not an expert on RO water but I was told that if you take out all the minerals in water then you have to put some back making RO unnecessary to grow unless your water is not potable to begin with. I Googled it and found this article and it might give you the info that you are looking for...
good luck

Rapid rooters have micro nutrients for 2 weeks and the seedling itself at this stage has enough energy to grow itself with very little water. I soaked the rooters in microbial mass water as well. Voodoo juice isn't available in canada right now.

With the light on I've caught it at 32 degrees and altered air flow to alleviate. Lux reading says 7500-8000 and seedling lux ideal reading is 5-10k
