pics of problems in veg and flower room?

[pothead42010]

here are some pics of my veg room and flowering room. in the veg ebb and flow with two m400 mh on for 18hrs. temp is 75f ppm is 1100 water did eveporate and ppm hit 1600 for a day till i corrected.ph is 5.8 for rockwool. leaves on my white widow mother are turning yellow with some spots.there are spider mites. i dont know if they are the cause think its something with nutrient but not sure.also one plant the leaves just dropped and looks like the leaves are just hanging.(on death bed)what to do?
then in my flowering room ebb and flow 2 400 hps at 12 i know i need more light working on that problem. ppm at 1000 ph at 5.8 with hydroton.temp is 70f humidity at 55%-75%.they are getting watered twice a day for half n hour. leaves are curling in and canoeing. growth is slow.now the leaves are starting to get spots aswell.dont know what the problem is either.

I know nothing about web n flow, but some of those pics show leaves that seem to be manifesting signs of improper pH. Concerning the droopy plant, I see what looks like your mite problem. Are those white spots on those leaves? Also, is it ppossible that he plant is drooping because it has too much water?

From what little I know about hydro and ppm, I would say that ppm is very important, as well as proper pH range: 5.3-5.8 (Don't quote me on that). I wonder if your ppm is too high, even at 1000. Wait, and some experienced hydro people will help you through it.

Also, I see what looks like a magnesium deficiency, but until you get the pH and ppm dialed in properly, you don't know if it is a deficiency or related to pH or ppm, or something else.

You say that you have mites. You need t get those under control immediately.

Good luck.

I am a hydro dude but not ebb and blow. Looks like you have been over fert them,,, pic 4 there is water or sumpthing on the leaves I wouldn't be folier feeding them. Looks like the majority of the leafs look ok. Maybe not using the right nuts or not mixing properly. Nut lookup? Pic 4 looks like the leaves look moist, feel the leaf it shouldn't feel moist{overfeeding or no fan blowing on the plants)

its just plain water on the leaves on pic 4 from a mister. the leaf is moist on that plant really moist. i have a fan in the room.
