Can any one help here are some pictures and here are all the details you may need to assist us.

Using Fox Farms Soil and nutes. We have 2 400w HPS and 4 225 diode LED panels.

Room temp 70 to 75
room hum 55 to 65

been in flowering nearly 2 weeks no signs of sex

the younger leaves seem to look nearly dead all dried and shriveled and the center on new leaves are yellowing. Some older leave becoming dry and brittle in ares and stooping. Please respond we need help.
Over all the plants seem a little unhealthy, not strong and vibrant. They were beautiful up until 1 week ago and now look worse every day. Only water twice weekly using distilled water ......mixed w/ FF nutes every other watering ......10 plants... Also some of the leaves new the top look like maybe a little yellowing or a much brighter green and look much more healthy then new growth near the bottom branch areas?????????

i would say, its hard without knowing all variables, but try lowering the amount of ferts you use, could be nute burn, but usually affects more than just the growth tips, kinda looks like either to much or to little water as well, letem get pretty dry before watering, dont want root rot. and also did u fluch them out before putting them into 12-12, you need to fluch out all those built up ferts every 2 months at least.

good luch man and lemme know how it goes

First, distilled water has a ph of 7.0, which is WAY high for your plants. At least add two cap-fulls of white vinegar to the water to lower the ph. Better yet, go to Lowes and spend $12 on a pool ph test kit. It will tell you when you are in range. Also, spend $20 in the garden shop at Lowes and buy a twin probe soil tester. In soggy soil, it shows the ph and nutrient levels the plants are receiving. Finally, it looks like you need some more light in there. Consider adding some CFLs.

Remember, low light levels and poor water quality, both look like nutrient problems. So, people change ferts all the time, when their problem is somewhere else.

Yes I have those things you speak of from lowes and i thought that you could not tell the PH in soil with organic soil????? Also I transplanted the plants into a larger pot just before 12/12 cycle would i still need to do a flush???

well u do need to give your plants at least a week to adjust to the transplant before you put them in 12-12. now ive never not done that so i dont know what it causes.
