Hydroponics

Hi guys. It looks like growinman may have a problem, but it probably is normal late flowering fading. You usually see this starting in week 7 or 8, and from the looks of your buds after 6 weeks, they may be finished by week 8 or 9. I would let it ride and see how they come out. Your op sounds like everything is finely tuned, so have a good harvest.

Now mendo definitely has a problem, on Day 21 and buds just forming. That looks like nute burn, and like you said, you noticed it and corrected the problem. But the damage done will not change, those leaves will not recover. What you have to look at is the foliage that wasn't damaged, is it continuing to change also. Are you using the suggested supplements with the basic nutes? The Uncle John's Blend is an important additive in that regimen. I talked with John, the designer of those nutes, several years ago, and he is a very smart guy. You should try calling the Cutting Edge tech support, they will help you.

This is all in the last couple of days. I actually top fed with very light nutes to flush down any collected salts. Then 5 or 6 days of light nutes through the flooding method. I started all this at first sight of those discolored leaves at the very bottom of the plant. I'm 2 days back on the 3/4 nute mix and STILL new discolored leaves every day. I was removing some of the worst ones but it's picking up so fast I dont want to strip the plant of all its fan leaves. All that you see in those pics was green three days ago! My res temp is regulated at 61 degrees. The room is 78-80 lights on, 63-65 lights off. I'm following the nute schedule exactly as specified. Mixing thirty gallons worth in forty gallons of water. I have an airator and a stir pump... I will call the CES techs though. Good idea

what is the ph of the water?

I PH it every day before it runs. I keep it between 5.8 and 6.0 ALL THE TIME! I'm totally aware how important the PH is to a system. Does any one think it could be a deficiency? Like I over compensated for a little bit of burn with too much flush? Or some kind of nutrient lockout? Rootbound maybe? I can still see a little rockwool through the roots on the bottom of the blocks. In addition to the fan leaves turning pre-maturely the buds seen small and slow to grow. Should I remove all the spent leaves or would that be too much of a shock to them. This is the second time I have grown this exact strain with an ebb and flow. The only differences are the temp; It was during the summer and alot hotter(90 to 100!) The nutes; I was using GH instead of CES. And the location; Could the water be shit where I'm at now? I let it set and stir for 24 hrs before adding any nutes or applying it. The first time it came out great despite the heat. I sure appretiate the help. This site is great.

i'm on my first hydro grow....i did outdoors for the past four years, but i'm starting to encounter slight problems with hydro. I bought a turn key hydro system (bc northernlights producer) and i'm using fox farm nutrients along with superthive, cal/mag, hygrozyme, and dark energy. I'm having problems with the one nutrient disolving in the water (fox's big bloom). It's a drip system and the pump only kicks on twice a day for five min. and because of the water sitting in the air bubbles the nutrients fall to the bottom of the reservor. Is this a common problem? Should i change nutrients or is there a better way of mixing?

EDIT: From that link could it be a Magnesium deficiency, (do you live in a very hard water area/?) Check online IE: google, Do i live in a hard water area.....If it is Magnesium or indeed, Potassium the link will advise you...

I would dredge the net till I found the exact same condition then follow advice...

Thanx Uber... That gave me some ideas anyway. I just cant understand how It went so wrong using only 3/4 strength nutes. The guys at the shop told me they use it at full strength with no similar problems. I couldn't be any more by-the-book with this run... I just hope I'm able to work this out.

I am currently growing with a top feed spaghetti line hydroponic system. My plants have gotten too big and I have to move them into a bigger tray. I was wondering if I'm able to go to a flood and drain system from a top feed. Would this be too much stress on the plants, or will they adapt?

As long as you don't let the roots dry out for any amount of time, your plants should be fine. Once roots get established, it always best to leave them alone, but if you have to move them to a different system, or bigger pot, they will adapt and continue to grow. You must allow some time for that to happen, and the plant will recover.

I have thrips and I heard that I can use nematodes to get rid of them. Can I when I am in hydro? Does this work?

You can use neem oil it works great for many types of bugs and its non toxic to your plants.

I've been noticing small black spiders in my room. I've flushed 2 so far. anything I should worry about? don't see any webs or plant damage yet.

im getting a missing security token when i try to upload pictures from my computer.. does anyone know why?

How small are they? If they are just spiders, they won't hurt your plants. If they are mite-sized, then you'll have to jump into action.

hey can you help me with some insight? i borrowed an aerogarden from work just to experiment. Bought some seeds from Nirvana ( Medusa, and ppp) and went about cultivating. i have some pics. would like some advice. are using the CFLs for now but i have a 1000w hps with ballast i was to use for flowering. Im at veg day 18. can i start to flower soon? this thread site is amazing lots of good people with good info. thanks for your time.

a 1000 watt hps for those few plants? guess you're expecting really nice results with that much light. I would wait until they are at least 12 inches tall to flower them. they will about double in size in the first 2 weeks of flowering, so be ready for that.

yeah its all i had access to at the time. i started to prune a little of the bottom fan leaves because they were being light blocked and one set of bottom nodes per plant to encourage upward growth. im going to buy a portable closet to grow in. i was reading on nutes the other day and i was curious about flowering nutrients or bloom enhancers.. do you have experience with these and/or your success?

I've only heard a little about bloom enhancers. I'd love to try them some time, but they can be a little pricey. for my day to day growing, I use general hydroponics floramicro and florabloom in the lucas formula, and add vitamin B1 to help speed up growth a little. anyone else use bloom enhancers?

HELP

So I thought I was ready to start growing, but apparently I need something called a TDS tester. When I was asking the hydro shop guy about it he did not explain it very well. What does it do? Do I need one? He said that I need to keep the # constant, between 500 AND 2000. What does that mean? How do I know what # to keep my plants at?

I NEED HELP, PLEASE!!!

read read read. a lot of good information out there on the inter web. TDS stands for total devolved solids. the amount of nutrients in the water. the number is in ppm, parts per million. to little and you'll starve the plants. to much and you'll lock out some nutes and the roots wont absorb them and starve too. also, ph is very important. keep it between 5.6 and 5.8. ppm starts out as plain tap water the first week from seed, then slowly increase it every week or 2 until you're somewhere around 1000 to 1200. some people go even higher. try the lucas formula if you're using general hydroponics nutes, search the forum for it.
