soil is organic. i have General Hydroponics (Micro, Gro, Bloom) nutrients. i water every 4-5 days give or take when need be. the reasons the bigger ones are overwatered is because my soil is not draining good enough. they always look like that for about a day max. the bigger plant in the back of the first pic was watered roughly one day before the other 3 bigger ones and you can see the leaves are almost back to normal. after they are normal looking again they are like that up until i water agian and the cycle repeats. they have also been given some nutes. i give them a nute mix after every 3-4 waterings. started at under 1/4 tsp per gallon each micro, grow, bloom mix and after 2 times i increased to roughly 1tsp each (mgb). they def love the nutes every since i started i have seen improvements. like i said in the first post none of the smaller ones have had any nutes at all. and i gave a mix of under 1/4 tsp mgb to the three small ones in the round pots. hopefully it helps. im running 7 42 watt cfl's in their. they are approximately 6 inches from light, yes i know its to far but i want them to stretch for cloning eventually. i am currently growing in the right hand side of my box only in the picture. i switched out all those 2700ks to 5 6500k's with 2 2700k's, all at 42 watts each. my temps max out at around 83. my humidity as you can see is 53% and temp is 77 degrees (took this pic at same time as first post). as you can see in the last picture the lower leaves on the back plant are turning a whitish, loosing chlorophyll, but they are soft. wtf??? havent tried the epsom salt yet. should i add that to the water or spray that on the leaves, i believe i read somewhere to spray it on the leaves. not sure tho, just burned a bowl. haha. thanks for your help by the way!
