the temp is about 80 in there because its been about 73 degrees outside here all week and its supposed to be like 50, so its possible that its a little warmer than they are used to. they've just got to the point where i need to raise the light about another 6 inches, which ill do tommorow morning. salt to water just to balance the ph, but i didnt think that it probably depends on how much my ph is off. from everything i heard epsom salt balances the ph in the soil, not just for mg deficiency. the one thats doing it the most is the closest to the light so i bet its the temp, no signs of burns or heat stress otherwise but i do need to raise it asap.
