aeroponic grow

It would be doable if the closet door were left open, and in addition to your oscillating fan you had a small fan blowing straight up at the light, and one blowing the heat from the light out the closet. Can't you vent into the attic or something? Otherwise I probably would go with 250 watt, then it wouldn't be such a big problem. That would be a nice size for that set-up, I think, but you still would need some good fans.

hey now,

so that blotchy yellowing on my leaves has gotten worse, in three days it has progressed from random yellow spots to lots of brown spots (see new pics) it's only happening on one of the plants (the largest one) and from my research i am pretty sure it's due to a calcium deficiency. That other plant (with minor yellowing around the edges of the leaves) seems to have a slight magnesium deficiency. So far the only nutes i've added are the pellets that came with the aerogrow unit, and i've added them as directed (i know---dumbass move) Is it possible that I have over-nuted? Any feedback on this would would be greatly appreciated.

Today I turned off the bubbles, emptied the res and tried to wash out all of those crappy pellet nutes as best i could, then refilled about 1/4 way with spring water only (about 1/4 gallon) and left the bubbles / lights off for the night. Today I am going to try to pick up some Fox Farms Grow Big to resume nute...here's my questions:

how long should I flush for?

when should I turn on the bubbles & lights?

how much water should I leave in the res while flushing?

Also, I have ordered a 250w HPS light w/ MH conversion bulb from inside sun, it should be here on friday, and I was planning on switching the lights immediately. Should I wait until the plants show improvement before switching the lights?

any and all feedback is greatly appreciated...thanks!

i have one of those, if your using the nutes it came with you got some ph problems, its too high, thats why your leaves are fucked up

thanks for the info on the PH

anyone have a thought on how long should I flush for and when it is ok to resume nutes?


thanks..

I was going to suggest a calcium deficiency is causing your spots, but reading ALL of the posts, I see you already came up with that ... sorry 'bout that :jointsmile:

Hey word, you don't really have to flush unless you are trying to fix a problem with a plant (as you are). But when things are running right, you don't so much flush as you do change. I would at least do it 2 or 3 times per month, unless you have some problems. If so it might be caused by your salt content being too high from lack of flushing often enough. When your res level gets lower, and you add to it, and you keep doing it, pretty soon the part that's left is full of salts and bad stuff, and your total PPM gets way too high. That's why we "flush" on a regular basis; to get that stuff out of our systems and get a proper nutrient solution in.

Now we also flush to get bad stuff out of our plants. When you are doing this you flush more at one time. It might be good if you fed with nothing but PHd water for a couple three days, changing the res once per day or so. That way hopefully the plant will at least get somewhat cleansed of the bad stuff. Then you can start feeding at about 1/3 strength. Start with 1 thing, probably your main grow nutrients. Watch for a couple days for signs of stress, then you could bump up the PPM or try adding an additive (perhaps two drops of superthrive), but don't do both at the same time. If you do any two changes at once you won't be certain which is the trouble maker. If your pretty sure you have a calcium deficiency, then you might want your second ingredient to be whatever fixes that, perhaps CalMag. That's pretty much what I take the other "flushing" to mean. But I wouldn't be surprised it's just because they gave you suckie nutrients, and once you start giving them some real food they will most likely start really taking off, and being healthy at the same time.

Oh yeah, I imagine that your PH is all messed up if you haven't been checking it. That is way more important than any recipe of nutrients. For your grow to be successfully you must buy a PH pen for like $25. They should have them wherever your getting the Grow Big. Also consider a PPM pen, as that's the fastest and most accurate way to determine how much to feed. Directions on the bottle are often a little confusing, but there is no confusion with a PPM meter. Perhaps you could save a little money and get something that does both.

Thanks for the feedback..I will continue to post updates and pictures.

Well?

I ended up having to wait a week for my nutes to arrive in the mail. I had them shipped and the shipper took their sweet ass time....anyway today I got some fox farm grow big (hydro formula 3-2-6) and also tiger bloom (for flowering). I emptied the res today and added about a gallon of spring water with grow big at about 1/3 strength. The spots on the leaves have gotten worse (see pics) and one of the plants has very curled leaves which I think is a phosphorus deficiency (again see pics) but needless to say none of my plants are in great shape. I should have my 250 HID in the mail any day now, it's an HPS ballast with a MH conversion bulb. so here are my questions:

1) Is it possible for these plants to bounce back? or should I scrap this grow and start over once I get my HID lamp?

2) what steps would you recommend I take from here? including nute schedule and when to start using the 250w HID. I am thinking I probably want the plants to show significant improvement before I jam them under an HID..

any help/suggestions would be greatly appreciated...thanks

nah, there deff fixable, you filling the water past that circle thing? + i would go full strenth on the nutes, you know wat the ph is? and some nutes have a ph buffer so i would use tap water

im feeling like you ph is a lil high, should be around 5.7
