Chocolope leafs Curling down and dark underneath

1) PICTURE OF PLANT *** VERY IMPORTANT ***
2) Growing indoor under 4 24" t5's, temp 70-80, humidity erratic (25-4
3) Watering schedule - kind of erratic - just when the cups feel light / and or seperate from the side, using a mix of ph'd tap water and distilled at 6.5, 1 drop of superthive per gallon, and just started a tiny bit of genisis b and 2 (1/8 tsp per gallon)
4) Growing Medium - pro mix seedling
5) What stage of growth - 10 days for seeds being put in soil (after soaking overnight)

two days ago I noticed a couple plants with wilting leaves, they are also looking puckered if that makes any sense. The underside is darker than the others. I put next to one of her more robust sisters for a contrast. Should I just lay off on the water for those plants? Anything else i can do? I also need to mention that the whole tray got knocked over that same day and I had to re set the plants. Added some dry soil around the base to prop them up some.

A side note, I have two Alaskan Ice in there too - they are strong as oaks!

You need to stop feeding them suprethrive. They are too small for any type of nutes because they dont have enough roots. I dont feed until 4-5 weeks old. Then only a mild solution. Watering when the pots feel light is good but make sure the water can drain.

it looks a little water logged,like the roots are starting to rot,you could put some heat under them to warm the soil,i find this helps especially when the temps are not to high in the room,it gives the roots a stronger beginning.but hopehully you get more replies.

Do you have any drainage holes?

Thanks, what about that dark color? I do have som drainage holes - i drilled about 8 little ones in the bottom and a few on the side. Trapper, if the roots are rotting is there anything I should put in there? Should I let the humidity stay low?

you said you dropped them and that upsetts the roots as well,if your rooots are damaged they are not drinking on full so they sit in moisture longer,i like to put heat under or put in a window with sunlight,sunlight cures all,but they will build new roots and helthy ones in no time,i just started useing thrive alive b1,but i never used it before and everything was fine,as for low humidity,i dont think you need to do that,because they do need to drink from the air as well if roots are damaged i would think,but just do the things i did you should be fine,and let them go untill almost completely dry.

I have a seedling heat mat in there to keep the temp steady (my house is cool) do you think i should put it back directly under the tray?

i used the same red beer cups last time for seeds,i had gassingoff from a grow tent which in the end caused root damage,i placed the cups in my clone tray,a plastic tray, then over a heat mat,my roots turned white and were vigorous within a week.it may be to hot right on the mat,but i did put them right on the mat untill my roots went to the bottom,the trick is for your soil to get dry but not dry enough for the roots to dry out and die.i too have a very cold house,my clothes in the bedroom has frozen too the floor in the corner many a times,good luck hope this helps.

Frozen to the floor! Man, I'll shut up - mine isnt that cold. Do you have probs with humidity? Mine was 20% in the closet when I checked last - 40 in the room around it! Hopefully when I go to a tent it'll be easier to control than that closet. Well, theyll be on the heat mat from now on. Thanks.

ya my humidity is 20-30 range in winter,no problems though,weed can survive in a wide range of humidity,i find the key is hetting a healthy root system going in the beginning then les problems as you go,and i found a little heat on my roots has always helped,remeber the humidity in the room may so or 40 but the moisture evaping from the soil is right around the plant so your good.

Alright, I just went to check on them after letting them sleep on the heat mat. No real change in the weakling - maybe a little worse but the cup doesnt seem to be drying much. However, a couple otherwise healthy ones have developed some spots on the first set of leaves. It almost looks like a layer of the leaf has been shaved away in those spots. Most of the cotyledons are yellowing so is it time to feed now? When the cups are completely dry should i saturate them and let the plants appear overwatered for a few days and repeat when completely dry? They all look really dry but are about 20 g heavier than a cup with just dry soil.

On a side note, one of the Alaskan Ice's (the two biggest ones in there) is starting to smell nice - is that normal so early?

- update i got curious and looking at the undersid it looks like the discoloration on the bottom has something to do with the spots. i cut off one of the leaves to take pics top and bottom - I really think this is some sort of ailment. I added two more pics of the leaf I cut off top and bottom view. You see that the darkness on the bottom is gome from where the spots are yellow on top, also the spots are bound in by the veins. It looks like domething I saw on other plants called downy mildew. So, not what? Do I pitch them all? If this is something that's all over plants outside will i be stuck without being able to grow?

it almost looks like thrips damage.

have you looked for bugs,i was just given 2 cuttings from someone with thirps,so im not sure what it looks like personally but if fdd says thirps im betting it is.it is always good to have a good thirp mite spray on the shelf.

also they do not look desperate for nutes so i would wait untill it drys a bit.

Yeah they dont look that bad at all. Have you ever pH tested your water supply. It may be off and causing that leaf chlorosis.

Ok i see you do ph test. I would just let them go and see if it gets worse. Other than a couple yellow spots they look fine.

Fdd, thanks for checking it out. There don't seem to be any bugs on any of the plants, the description of Downy Mildew fits it to a tee "On some plants, downy mildew infection may look similar to injury from foliar nematodes. In both cases, angular lesions are bounded by leaf veins. However, downy mildew infection results in a soft, fluffy gray, brown or purple fungal sporulation developing on the underside of leaves." See: http://www.hort.uconn.edu/Ipm/greenhs/htms/downymlgh.htm but now I don't know how to treat it without causing damage to these fragile young plants (maybe their not so fragile???) THe intial droopy one is about to get separated and doused with ortho ecosense (.08% copper octanoate) because it's the only thing i could get right now. As for the rest I'm gonna try to keep the temps above 75 becuase supposedly it doesnt like that. The only thing I can't figure out is that my humidity in the closet hasnt been over 50% but I guess it must be higher right there at that first set of leaves??? From the article it sounds like the spores are everywhere you just have to make the environement inhospitable. An article about growing chocolope mentioned a spray "Also after the first week I begin my spray program of Neem oil, Clove oil, and Garlic oil. I sprayed every 3-4 days up into the 3rd week of flower. I have found if you spray kind of heavy in the vegetive state and into 3 weeks of flower you usually wont have a problem with bugs or powder etc." Any idea how to make this? What do you guys think about the ortho ecosense stuff - will it kill the seedlings?

Another thing, I do have an ozone generator - should I plug it in and hope it kills the stuff?

i just use the stuff safers makes cant remeber what its called,but i never had powdery mildew but i have sprayed for mold useing the safers stuff i believe you can use it for powdery mildew,i will try and find the label see what its called.but do not baby them to much,you can kill them with kindness.

also i have had those white spots on early seed leaf and it just grew out of it,either the powdery film on my leaves were something and went away on its own or it was nothing.
