First Indoor Grow 400 Watt Medical

This is my first real grow attempt. Legally at that. Specs

400 watt air cooled glass covered HPS/MH
4in 160 cfm fans intake/exhaust

Started from bagseed.


I just returned from a 4 day trip to this. They looked better at the beginning.





1 plant has a severe nutrient deficiency i think nitrogren, and the others are potassium or phosphorus. The ph of hte soil with my junk reader says 7, but the run was at 6. I think they are in the stages of lockout, so Im gonna nute with big bloom (organic) and check run off, and thenif I have to raise it with an organic compound.

The temp stays between 70/80 humid is 40-48%. Light is 8 inches away (temps good). I water usually everyday other everyother because the soil drsies out very fast.

I plan on using all 6 ff nutes, and my next grow will be premium seed, with all advance nute, and another 400W light. Please help me out. Thank you.

BTW I am a disabled vet USMC infantry (Iraq/Afghan), and use marijuana strictly out of hate for opiates, and i believe in natural healing.

Sorry to here you are disabled vet but thank you for serving our country. Well ill do my best to help I think you should use plane water for now untill you get your problume fixed. Do you use ro or tap water. I would try to get PH at around 6.5 raise your light about a foot. Soil well if the soil is dry on top it might still have moister towards the bottom I water in veg about 3 to 4 days depending on the temp in your grow room. How often do you feed your plants and if you use Fox Farm I would only use half of what they recomend.

I havent fed yet as they are only 13 days old. How should i raise the soil PH?

what kind of soil are you using?

I just fed for the first time with a very very lose dose of big bloom that ff organic. I will do it every other watering.

im using ff ocean forest. The ph run off is very low... So the nuted water I just fed was grow big with a ph of 7.0. I think that should help even it out. Am i wrong/.

Thanks for your service sway. You are doing the right thing staying away from the opiates, I've seen them mess people up really badly.

To raise pH, get some pH up solution along with a test kit from a hydro store. They sell kits that have pH up, down,and a test kit for around $25. Usually your pH will be either high or low all the time, so you only really need either the up or down. If your pH is off, some nutrients will be unavailable to the plant, so it is really important. I have good, clean mountain water so I thought I was all good, but when I got a test kit I found out the pH was around 8.

One more thing, yeah take it easy with the FF, I've heard it runs pretty hot at suggested doses.

Oh, I see you test already. Yeah, if your runoff is low, pH 7 should be ok.

7 is too high


Ocean Forest is not hot unless you add nutes during the first 3-4 weeks of veg. OF has the nutes already in there and since you are adding more you might be burning the plant.
Best thing about soil is you can flush and start over in a few days

Cool charts jesus. I was saying since his runoff is acid, it would be ok to water with basic water to try and bring pH up, or am I mistaken?

if his runoff is 7 then whats inside is probably higher or maybe i am just missing the point which is possible.

the PPM of the run off of the nute def plants was almost 2000! i flushed and got the ppm down 400 and ph at 6.7. They should come back strong right?

My run off is low jesus, which if you water with a more alkaline water it should raise the soils ph in theory.
