My guess is you hit them with to strong a feed. Sounds like it was the first time you fed them and gave them a bit too much. Just plain water the next few times they need water then SLOWLY introduce them to the nutes.....

This is nutrient burn. Make sure you are mixing correctly. I've seen terrible result with flora nova if your not careful. On the other hand flora nova used properly has been among the best buds I've seen. Flush it and do some reading to prevent this from happening again.

I'm also gonna say no, its not heat you have the perfect temp. In fact 20 inches is too far, you plant is stretching to the light. Move light to 12 inches and you should notice the new growth closer together. The further away your light, the greater the lumen drop.

Taco leaves and coconut soil?
How much nutes did you give'em?
Do you use a ppm meter and know your ppm's?
