Looks professional, large plants or mothers in the single hole tubs?? Is this in a journal somewhere, I'd like to find out more?? VV

all the plants shown in the pictures are vegging the mother plants are kept in a different location . part of a new cultivation coop between several farmers. the strains inthe picture are newberry, ak-48, and nothern lights had cherryslider but did not do well due to overwatering from res tank getting to hot
Here i have included some pics of problem form the resevoir being to hot, so others can identify the problem

I am working on my first grow and am a little unsure of how my plants are progressing. These were started from bag seed (I know - bad idea), and have been under fluorescent lights & getting nutes for just over 2 weeks.

They are in a dripper system that's set to drip 10min every 4hrs - lights are on 24hrs and set about 4" above plant tops.

I'm guessing that #7 should be put out of its misery due to the odd loop at its base, and slowish growth.

#10 started out neck and neck with 8 (the biggest one) then suddenly slowed. Seems now that it has 2 heads!?! :o Has this plant basically topped itself?

I'm not seeing any major problems overall, but seems most of the plants have some sort of "character mark" here and there.

...just looking to see if the wise folks of Rollitup see any issues...

If those roots are slimey and break off easily, you have advanced root rot. You already know the problem, your res temps must stay below 75F. You may need to start over, or at least cut that plant back, and let her recover.

Whatcha think of these spots??
Noticed it on my best one this afternoon...

That spot is probably a result of nutes, so maybe flush some plain water for a day, or cut back on the concentration a little. Your plants look just fine, and you will always notice little differences as they grow. Using bagseed, you may have a different looking plant from each seed. And your biggest and fastest growing plants will usually be men. Those branchy and smaller plants are the girls.

But it's easy to be fooled, so you still have to properly verify their sex. :blsmoke:

Keep your fluorescent tubes 1 inch above tops as best you can. You are probably watering the cubes too often, I would do it once a day, and see if the cubes stay wet enough. Once you get the feel of the weight of a wet cube, it's easy to check by picking it up.

Thanks for the feedback!
Did some digging around online last night and pretty much came to the same conclusion... overwatering...
I cut back the watering from 10min every 4hrs to 10min every 6hrs. I'll watch them for a couple of days and we'll see if there are any changes. If things don't start looking better I'll cut back on the watering some more.

Thanks to everyone on this forum - what an excellent resource for all us newbs :weed:

Yep - definite overwaterage :(
Only a couple of my plants are showing the sickly roots tho, so hopefully I caught it on time.
Decided to leave the pump off the timer overnight to give them some time to dry out more. I lifted each cube to try and "spin" them a little drier, but none even let out a drip (I didn't "spin" them very hard either).

Is there any way to tell if a plant should be put in a pot by how many roots are hanging out the bottom of the cube? I was planning to put these into pots of hydroton at around 4 weeks (next weekend), but am wondering if this one shouldn't be moved now - thoughts??

So, here's a shot of the (hopefully) early stages of root-rot - both roots and top...

I don't see any sign of root rot, everything looks healthy. When roots stick out of the medium into the air, the tips die. I've always called it "air-pruning." Whenever you put your rockwool into pots of rocks, the roots will start growing out of the cube again. It would be best to put them into the rocks now, while the roots are still alive and ready to grow.

Excellent - thanks again for the info potroast!

I was reading the Al B Faqt and saw a mention that GH Flora series are not compatible with H2O2. There wasn't much in the way of explanation, nor corroboration. Do you know anything about this? I'm using the 3 part series, and had been dosing with H2O2 per Al. Other than the one plant with the spots I haven't seen any issues, but if H2O2 is neutralizing some portion of my nutrients I'd like to discontinue it.

Also, I've seen mention in the forums about giving others +rep points. How does one go about doing that? I've looked high and low and can't seem to find where that is.

h2o2 kills living things, if your using organic nutes, it could effectively kill them. To rep someone you click on the little scale of justice, upper right hand corner of the post. This will bring up a dialog box where you put your comment, I always try to let the person know whp gave them the rep, I just put VV at the end. VV

oh shit, me too. lol. i am using 35 h202 and i wondered if i should be using hygrozyme, or guard. I read the same post but it was so long ago i figured he meant botanicares or something. They are organic. Wait, lol, i am being jogged as I type, i rem something about nutrient numbers and it was inconclusive. I lost it. I hope not, i dont wanna repurchase everything again. Thought i could relax for a min or two.
I have noticed nothing but better plants since i began h202. I was having probs. Ph probs i think. So i cant say i have noticed anything bad form h202. I will look or call a hydro store for us. Later though i work this morning.:fire:

lol i have been through this query before so perhaps my responses from growers like AL b and Earl may help u.

If you are using hygrozyme do not use h2o2

if you use h2o2 do not use hygrozyme

I think somehow they can be used together in small quantities or something...but they basically do the same thing so forget about it. Just spend the $ on some hygrozyme if your using organic nutes and 35% h2o2 if your using chemical nutes. Yes the GH flora series is "hydro organic" or for the sake of this question...organic.

JUST BE SURE TO NOT PUT your high powered H2o2 in a organic soup. :idea:

and now i has a question.

I am wondering what your favorite reflectors are Potroast. I would like to try a simple adjust a wing with cool tube, but recently realized they are actually a lot more expensive than the huge SS white box reflectors I am used 2.

Any prefernce or just as long as da lumen get to da plant it good.

I think AL b said cool tubes are more efficient at cooling (makes sense for low powered fans) and they also distribute a larger field of lumen's ( aka 5x5 out of a 1000watt instead of 4x4 at the same heights)

Sounds like a plan, although seems the consensus is that GH contains some organics - shooooot.
I sent an email to the GH tech support address last night asking them about using H2O2 w/the Flora series - will post their reply when I get one.

I built this based on AL's measurements. The next one will be simpler and cost less. I learned some of this is really not necessary. I bought the cooltube for a $100.00, built the Batwing reflector for $50.00, the ballast for $170.00. VV:eyesmoke:

I cut back the watering to 3x per day for 10min each.

When checking on my tank this evening I noticed some whitish/grey slime here and there, so decided to change it out. I cleaned everything with bleach water and then rinsed the hell outta it with plain water. Remixed my nutrients and totally left out the H2O2 (I had started the last tank with it, but discontinued when I found out that GH nutes likely contain organics). Lowered the pH from 7.0 to 5.8 and ppm 407.

I checked the pH a couple hours later (pump hadn't run yet) and found it at 6.2, so lowered it to 5.5 this time.
I'll recheck in the morning after it makes it's first scheduled run on the new tank. (Checked in the AM - tank was at 5.8, so left well enough alone)

Woulda added some pictures, but jumped to action too quick and had things cleaned up before I thought of it.

I've attached an image of a plant that's N deficient. Unfortunately the image isn't super close/sharp, but kinda looks like my plants (see previous post) - do you agree??? If so, could it be that the H2O2 I added to my tank last round destroyed the N and thus caused these issues in my plants? ...or do you think it's just a case of over watering???
