I'm not too sure what is florescent. Do u mean CFL lights? OK cool didn't know that! Is the LED 300w too strong in the beginning? I realised I may have gotten soil that's too hot for the seedlings and should have gotten seedling potting soil as opposed to professional potting soil which I got.
Thanks man! That is the one thing i wasn't able to check was the pH level of my filtered water. I didnt pH it down in case i over do it so just plain water with seaweed extract. Now i stopped the seaweed extract all together because i thought i was nute burning. I will try plain ph'd water with cal/mag and see what happens thanks!!
So I got my pH meter today. the RO water was at 8.6pH :sweating: and after i added some nutes, it drops down to 4.0pH. I think that was why all my nutes were locked out and all the plants started dying. i have flushed all of them with RO water at 6.5-6.8 so hopefully now they will be happier.

If you have usable well water or tap water, fill a 5gal bucket and let it sit for 24hrs. Mix 50/50 RO and tap before adding your nutes and your ph wont swing so bad when adding nutes or ph up/down. A few drops of acid or base will make straight Ro swing whole points on the Ph scale on a meter and it isnt accurate, you need water with some minerals in it for your meter to read right.
