looks like fert burn

1. hydro, soilless or Soil & brand name of soil ?
2. PH of reservoir solution?
3. PH soil runoff?
4. PH of water?
5. Age of plants?
6. What Fertilizer, dosages, and frequency?
7. lites, wattage & proximity to plants
8. Light cycle. 24/0,, 18/6,, 12/12?
9. In light cycle how long?
10. Room temps or reservoir temps

foxfarm ocean forest soil. I'm not sure of any of the pH but I use distilled water.

plants are 19 days old from germination and have been under a 400w HPS light 18/6 since then.

the only fert I've used is pure blend pro grow which I've been using for 1 wk at 1/4 the dosage (7ml per gallon). Yesterday I watered with 1/2 the dosage (15ml per gal.) I water each plant 200ml of water daily

temps are 80s but occationally can get up to 90s

fox farms soil contains organic ferts ....which have shown to be too hot a soil in itself for some seedling which need no ferts for the first 3-4 weeks in soil

and your supplement feeding on top of that

as young as your plants are I wouldnt bother flushing to leech the ferts from the soil, just transplant to fresh FF soil....water only for 3-4 weeks then start off at 1/4 strength ferts
