I recently went on a trip (as I routinely do) and as with any trip the chances of coming home to an issue is medium/high. This trip was no exception to the rule.

I have 4K in flowering in various stages from week 2 to 8 with a total of over 50 plants.

All are in soilless sunshine 4 1 gal pots on a flood drain system getting watered 2x per day during the light cycle.

The room is at 18-22C day and 14-18C at night. All plants were subject to the same environment.

Two plants, one in week 5 and the other in week 2 (again subject to same conditions as other similar plants in their trays) went saggy. They are in different trays. When I describe saggy I am NOT referring to lack of water droopy which we have all seen before, but instead the leaves seem to not jump up towards the light like their sisters and some of the top leaves seem to be turning a dark dying looking yellow. They are slightly waxy. They do not seem to have nutrient burn marks on their corners and they are Green Crack variety which are very reliant to over-fertilization.

Sorry I have no pics at this moment.

Any idea why only two random plants have this exact same issue? While 40+ of their sisters subject to the same environmental conditions are just fine?

Could it be a disease or fungus? Should I do a H2O2 flush? I think it might be overwatered?

It has been four days and they don't seem to be changing (not getting better or worse) and environmental variables have not been changed and their sisters are still fine.

Any insight is appreciated.

Unfortionatley some plants just fall victim to random unexplained problems (Genetics,Stress while seedling, ect...). Maybe try moving them around in the room to see if there condition changes due to location in garden. Sorry without pics its like shooting in the dark.
