clones in rockwool: yellowing and care tips

[Guest]

thats exactly what I do. helps it stand up better. also, should make sure it block all the slots in the netcup so no light gets thru to the res.

If it were you, you'd have some serious nute burn

Oh well,,,,theres a first time for everything i guess.

last nite I transplanted them a great deal deeper into the net pots, and raised the water level again. I think they're drinking better.

the plant that almost collapsed from wilting is now perked back up...but its bigger bottom leaves are dry and dead. oh well.

gotta give them another 4-6 hours and see how they do.

My GF is off to the aquarium store to get a couple small $20 air pumps to increase bubbleage until I have a solid day to switch to a snazzy, more manageable bucket setup. (which may not be for a week or so)

Since we know the ph is low enough, we can rule that out. When a plant gets damage to its root tips it will show iron deficiency first. This would show up on the newest growth first like what your plant is doing. Yellowing new leaves. I think ph 6 would work just fine but don't let it go higher. Just a thought.

UPDATE

• well, I can't even get the water levels and bubbling amounts consistent with these damn tubs. Some of the rockwool cubes are almost soaked, some is bone dry. Its wierd. These tubs gotta go.
  
• All of the bigger leaves look terrible, but theres tons of new growth at the nodes on all the plants. Pics at the end of the post.
  
• pH is climbing steadily...I've had to adjust it down twice from 6.2 back down to 5.8 with about 3-4ml of pH down per tub. but they're not eating...260ppm still, no change since i mixed the nutes. what gives?
  

check out these macro shots of the new growth and struggling big leaves:

well they wont be eating yet really, the roots havent even hit the rez yet. to force them to hit the rez faster, you want to make them work for it, not get lazy.. so you wanna make sure water level stays 1" or so below cup.. once roots hit rez they begin to eat.. dont worry man they will snap out of it, just get them into buckets..

 

[sproutco]

Looks like your getting some serious root issues going on.

 

[cultiv8t0r]

tell me more about these serious root issues?!

 

[sproutco]

You started out with what looked to be iron deficiency. Like your roots are in trouble. Your plants are starving for some reason or lack water. You should increase your nutes. Maybe handwater till they reach your rez water if that is what is going on. I am really high lately cause I got an eigth of buds so bear with me the next few days.

well no offense sproutco but I jsut wanna say I disagree on increasing the nutes.. they havent even hit the rez an arent even really eating much ..

however handwatering for nute delivery isnt a bad idea - the issue is they are apparently already saturated, causing DO problems, and that may just contribute to these problems.

the problem with your girls and oxegyn sounds similar to that of "mindovermatter", read his post. his rockwool was staying wet, and so his girls (about same stage as you) werent getting enough oxegyn, as they hadnt hit the rez. also he filled in with rockwool, not hydroton, so THAT was stayign wet.. I think you have a similar issue, sounds like water levels too high..

i am gonna go on record saying i think ALL your problems will be fixed by going to buckets.. no question about DO issues, and as a result roots will pop thru and eat fine.. and as they eat theyll fix current def's.. it probably isnt even accessing your rez nutes yet because the roots arent developed.

 

[sproutco]

So that's two votes for handwatering. You have to have the nutrient solution salty enough for the plants to take up salts. This principle is called diffusion. Salts move to a lower concentration like in the plant. The nutrient solution and the plant try to become equal although a membrane seperates them.

^^ i hear it. how about handwatering with nute solution in a sprayer several times a day? how do I make it salty, right now its just botanicare nutes and DO water. (which i get in mass quantities from the supermarket in water skins, I feel like a friggin camel...side note how the hell do I install this ebay DO filter system without a plumber?! it seems to need an installed faucet and pressurized storage tank.)

i think the h20 levels are too high now...and previously they were so low they weren't getting anything. Haven't been able to dial it in. I there is so much water in these tubs that the bubbling doesn't send moisture very high.

sure, they can't be eating anything if ppm hasn't changed, right?

im sold on buckets for sure, by your opinion and my previous exp. with them.

But that won't be until tuesday night or so...I need to try to optimize the conditions until then.

NO spray. Just drench the media. Spray is for emergencys.

 

[cultiv8t0r]

^^ got it....how frequently would you think? (sorry I have to be spoonfed all this info...)

 

[Guest]

there is NO such thing as too much oxegyn in a DWC sytem

 

[sproutco]

You must spread some Reputation around before giving it to the lorax again.

 

[cultiv8t0r]

Unfortunately my camera is malfunctioning, otherwise I could show you there is a new trend of red chlorlphyl showing through the leaves...there is less yellow present and more of this dark red hue. I did note that the temps have been lower, dropping into the high 60's--so I've been creeping up the AC. Sorry for the lack of pictures, I'll get some up tomorrow.

Any and all thoughts greatly appreciated.

 

[cultiv8t0r]

Good news! The majority of the plants have one pure white growing out of the net pots!! (4 out of 6)!

 

[cultiv8t0r]

should i still hand water the plants with a root (singular) in the nutes? PPM is steady at 250-270, and pH keeps drifting up. temp 68 F.

 

[cultiv8t0r]

Hooray, I found my back-up camera. Here are some picts of my reddish leaves:

Here is the newly sprouted root from that same plant:


And here is a pic of one of my plants that has three roots peeking out!


pH 5.8; temp 68.4; humidity 40%; ppm 280; 10/07/06
