2 Problems, +rep for help

I'm having two possible problems, one with a plant and one with clones.

The first 6 pics are of my Opium. She'll be 4 weeks old Friday, I got her as a clone.

I noticed little white dots on some of her leaves when I was filling the humidifier. When I puller her out of the room to take the pics I noticed what looked like nute burns on some of the same leaves.

I made a newbie mistake when mixing the pots, I mixed in bone & blood meal with FFOF. Not much, only a couple of table spoons of each in each 5 gallon pot, but I've been getting minor nute burns and I think minor stunted growth. The burned leaves only show up once in a while and this is the first one in almost a week.

I'm worried they might be a sign of spider mites, but I looked under the leaf and didn't see anything. Could these white dots be nute burns?

If they are nute burns, can I use them for clones, or do I just have to clip & toss?

The other pictures are of leaf damage on some of the clones that I've been rooting for about a week. The brown spots worry me. I have them in 99% humidity and I treated the water with Hydrogen Peroxide to try to prevent mold/mildew. Could this be mold/mildew? Nute burns? (I have them in FFOF & Perlite with nothing else added) Or is that just natural for leaves that are dieing while the roots develope?

Same basic question on the light color leaves. I'm pretty sure it's not mold/mildew, but can it be nute burns already? Or just what a leaf looks like when dying while roots develope?

Sorry if any of those questions are "newbee-ish", but I can't find pics of plants with these problems anywhere. And I guess this is how we learn.

Thanks for the help +rep

Are you just talking about the plant that's veging, or the clones too?

The mix I used was 1/3 perlite & 2/3 soil. I also haven't watered in 3 days. So probably nute burns, right?

clones will not tollerate drying out its totally up to you to manage the soil as an evenly moist yet not saturated medium

Take a look through this, I think you'll find your problem:

Your mum plant pics are a bit blurry (hard to get those close up shots to look good) to say for sure that its not anything else but I can definitely see nute burn in there, and your young clones I can see nute burn. Also remember a bit of yellowing in clones is normal as they try to establish their roots, they need to get food from somewhere so they take it from their leaves.

again Krust real info that is useful , i would rep you again if i could

Have you got your clones in a humidity dome, or something of the like. Until clones have roots they cant take on water unless in high humidity conditions, regular spraying 2-3 times a day is also required for clones otherwise they will dry out and die which is what looks like has happend in your 7th and 8th picture.

Thanks again, I never even thought about soil moisture. The top layer is staying moist thanks to the 99% humidity but it might be dry where the roots would sprout from. I'll have to check that right away.

Thanks for the good words and rep. We all got to learn somewhere and whats the point of knowledge if we don't spread it about.

I checked out that thread before posting here. On the vegging plant the edges look like nute burns but the little white dots look like spider mite damage.

I guess it could also be Thrip damage. But I looked for bugs pretty thoroughly and didn't see anything.

I figured the clones could be deficiencies if they don't have roots yet, but wanted to make sure the brown stuff wasn't mold/mildew since I can't find pics of that.

Sorry about the pics, my cam also sucks. I'll be getting a real digital camera on my first harvest.

The edges definately look like the minor nute burns that I've been seeing. But the little white dots are new, they look kinda brown in the pic but they're white. Should I just spray them to be on the safe side, or will that stress out my plant? (I bought Mite X because of the low humidity here)

If spraying is a bad idea when not absolutely neccessary, should I just clip the leaves and see if the white dots return on a different leaf before I decide to spray?

I thought that brown spot looked like a nut burn which I guess is possible with FFOF & young plants. But I though "nah, they've only been cloning a week, they probably don't have enough root material to absorb enough nutes to cause a burn. In this case a nute burn is good news, it means she has roots. I'll have to keep my eye peeled for new growth so I can take her out of the dome.

I was short on cash so I tried something of my own design. I took 14" saucers, put water in the bottom, and used the tops of Pepsi 2-liters as domes. The water constantly feeds through the bottom of the pepsi domes and keeps the humidity at 99%. I was woried about mold/mildew since I don't open them but someone suggested adding Hydrogen Peroxide to the water to prevent mold/mildew and I guess it's working so far. The temp is constantly in the mid 70's and I have four 4' fluoro tubes 11.5" above the tops of the cups. The only unexpected surprise is that I have to turn the domes 180 degrees once a day to keep the humidity at 99% without misting.

I ran out of pepsi domes and added a big red tub with glad wrap over it. Water in the bottom treated with hydrogen peroxide. It's stays 80 degrees and 80% humidity in there. I haven't been able to determine if the tub is better than the pepsi domes or vice versa yet.

I actually clipped that dry leaf earlier this morning. I just thought it would help to have views of 2 different leaves. But that's why it's so dry.

So what does everyone think about the vegging plant. Should I leave her alone for now & see what happens? Should I clip the leaves off and see if it returns and spray if it returns? Or should I just spray her now?

BTW, I just added UVB lights to the 400w MH & 400w HPS about an hour ago. I understand the UVB is good for some pest control. Does anyone know if UVB works on getting rid of Spider Mites or Thrips?

Sound like a good little setup. Hydrogen peroxide is good stuff, only used it in my hydro setups and I like the way you have put it to good use in yours, remember though it needs adding every day to the water supply as It has a short life and leaves the water quickly. 80% humidity is high enough, so to choose whats best between to two systems I would choose the one that's the least maintenance.
I think your doing well, learn your lesson from the nute burn and you will be alright. As for the suspected infestation I will suggest to just watch closely for now, you say you can't see any little buggers in there and its not spreading then leave it be for now. If you have the nute burn under control you shouldn't see things get worse if they do then treat it for the pests.
Hope I've been of some help and best of luck

its hard to pinpoint the excat cause due to blurry pics, but there is a lockout going on......i personally think from what you have said is your soil is too hot i would flush and transplant it just straight fox farm......right now because your soil is too hot your ph is out of wack causing the lockout.....so your actually over ferted and defecient. a good flush and transplant into moist un amended soil. shell be right as rain in a week.then start feeding lightly every other watering.
the clones if not rooted look over hydrated if they are rooted they are dealing with the same issues as the mom.

Thanks, I just tried to +rep you again but it wouldn't let me.

I didn't know about adding more hydrogen peroxide every day, something else that I have to get on right away. The tub is lower maintenance, I was just woried because the plant tops are 80 degrees which I'm told is a little too hot. But so far so good.

I can't say the nute burns have gone away, I thought it was over already. I'm not adding any nutes of course, just waiting for the FFOF & bone & blood meal to get absorbed or washed away from watering enough for the nute burns to stop. Should stop soon though, they're getting more & more rare & farther apart.

I'll take your advice on the possible infestation. But I'm probably gonna remove that one leaf with the nute burns on the sides and I'll leave the other 2. Hopefully it's just some kind of weird nute burn and if not, then hopefully the UVB gets rid of them. And I'll save the spray for a last resort.

Thanks again

looks like i showed up late for the party hope you get it sorted bro...

I made a newbie mistake when mixing my pots and added 2 tablespoons of bone & blood meal to each 5 gallon pot of FFOF. I've been dealing with minor nute burns since day 1, but they've been getting less and less frequent as time has gone by. It's been 5 days since the last nute burn. Do you really think I have to transplant them or you think I can get away with it since the nute burns are getting farther and farther apart?

By over hydrated do you mean from soil moisture or from the 99% humidity in the air?

I was thinking I might have some nute problems because FFOF is so hot and the plants are so young. But that should go away as the plants get bigger, right?

The pH of the soil is 7 and the pH of the water when I watered last 3 days ago was right at 6. This was one of only 2 plants that I watered at 6, the others were watered at around 6.3. That should be a good pH level shouldn't it?

what you have to measure is the ph of the runoff that will tell you the actuall ph the plant is in.and how to adjust. 6.2 to 6.3 is a ideal ph for most strains some like it a tad lower some a tad higher.you will know when they are happy.The clones i take have not rooted.....I would consider using another method trying to root in soil takes longer and is harder to do.if the humidity in the room is that high that is also a problem you are vaunarable to stunted growth powdery mildew mold etc.......while developing roots that kind of humidity is in fact needed. once roots are developed then temp, low humidity, and good air flow all are vital compontens to a healthy cannabis plant....... be well. grow on...
