E-bottled water
Why are you using bottled water? If it's drinking water then often times it has sodium in it to account for human taste. If you use store bought water then you want to use distilled; however There is, TYPICALLY, nothing wrong with tap water. Tap water has Calcium and Magnesium in it, something that bottled water does not have and you would have to add through a supplement like CalMag. Calcium/Magnesium is essential for plant life/health.

Switch to tap water unless you are running water from a well and you know your water is bad, otherwise be sure to use DISTILLED water with CALMAG.


E-Source water 6.4
You said your soil runoff is 6.2? That's still within your threshold however you want to try to be at about 6.8. Adding dolemite lime is a pain and would have to be added as a tea. Even then it would wash away. Water your plants with water ph'd at 6.8 - 7.0. This should bring your runoff ph closer to 6.5 which is much more ideal.

E-3 weeks
You're a bit early, but I would check the plants for root bound conditions. While the soil is moist (not wet.. but just moist) gentle put your palm around the stalk and turn the pot upside down and wiggle it out of the pot. Check for root bound symptoms.

If you are root bound then now is the time to transplant. This would also address any ph issues you may be encountering.


E-dnf gro for seedlings and cuttings
How long have you been applying this? This is a hydroponics nutrient line.. not a soil based one. Which will really screw up your plants if you are dosing the hydroponic solution for your soil plants.

Simply Hydroponics - DNF

Flush your plants right away with ph 6.8 water, 3 times the pots size in volume of water (ie: 1 gallon pot = 3 gallons of water ph'd at 6.8 slowly and gently poured into the pots allowing it to drain very well.) then give a very very very light feeding (1/4 dose or 1/8 dose) of a good soil based nutrient line. Fox farms is a good place to start. Many people here like it and will attest to it's quality.

E-400w hps 3 ft from plant
E-day 30 deg and 50 humidity , night 24 40 humidity
30 degrees? YIKES!! That is way too hot. Photosynthesis is optimal between 72 and 78 degrees F (22-26C). For every degree over 78 photosynthesis drastically declines until you hit 85 degrees where it nearly comes to a halt completely.

You need to cool your plants better. What is your ventilation setup like? you need to have an exhaust with a passive intake. I'll get to that later.

What is the size of your grow environment? Also I noticed you're using mylar. Mylar will create hotspots. You will want to rip that down and paint your walls FLAT WHITE.

Again, what is the size of your grow environment? This is a very important question in relation to the lighting you're using.


E-air purifier and ocsilating fan and 465 cfm fan blowing through light box for 400w hps outside , no fresh air except when door open and air purifiers
Your air purifier is probably just wasting space. I would remove it. Heat will occupy a space until that space reaches the same temperature as the radiant heat source or higher. At which point heat can no longer effectively move anywhere and just builds hotter and hotter.

What this means is that any space you can free up is beneficial in a small grow area as it will help, slightly, reduce heat.

In addition your 465cfm fan.. is that an inline fan? If so you want to have it set to exhausting your room. Using it as an intake is just blowing hot air around. Your goal is to exhaust all the cubic feet of air in your grow environment in 5 minutes. I personally like to exhaust all the air in the room in 1 minute.

Are you running a cool tube or air cooled hood or anything of the sort to isolate the radiant heat coming off your light?

E= media was claimed to be pre nutrianted
This is a HUGE nono.. You want your plants to be in a non nuted media to begin with. Try using peat pucks next time or running a very good flush on your media before you use it.

Seeing as how it's too late for that now just be sure to follow the steps I listed above for flushing the plant.

there about 8 inches tall showing reddish stalks stem is green and starting to flake and leaves are curling down and the bushy one is curling up a little dark green in the middle of leafs and turning yellowish on the outside except the bushy one what could be happening ?? over nute not enough of the right kind , and suggestions for the room or ideas how to fix it up or the plants
You're doing a multitude of things wrong. Read everything I wrote and apply it to your grow. They can recover.

In order of importance:

Reduce heat
Change your water source or add CalMag
Flush your plants
Change Nutrients

Anything else I listed comes after that.

Good luck.
