Noob attic grow, 2 plants. Question about smaller one.

[heter]

Hi der. I started a 2 plant grow using a 32w cfl in my attic. One of the plants seems to be doing fine, but the smaller ones leaves are kind of... crispy. I watered that one more than the bigger one. Heres 2 pics of the plants. These are the best ones I could get (this camera is terrible).

Miss female is the bigger one. The smaller one is Miss Lady.





The big girl did a little bit of stretching at first because I was using an incandescent light, but she hasnt stretched since I got that cfl. The only thing Ive done differently to the small one is water her a little bit more than her sister. So whats up with the smaller one?

[xsuperx]

i cant tell if it has holes in bottom or not but if so ;i fink u need a pot with holes in bottom so it can drain unneeded water, be carful when trasfering though as your roots may have aredi rotted

Both pots have 4 holes in the bottom.

the soil looks very poor quality, also check ph level (i recommend arond 5.5),
and also could be nute burn, check soil bag for nutrience, if it haas any added nutrience , or high values, then scrap it as the plant doesnt need it this early in its life. you should scrap it anyway.

soak the soil so its like liqid, then take plants out, wash pot, new soil in with hole in middle, put plant in and soil round it then water - this may stunt growth whislt it is recovering

hope all goes well

also, try using glossy paper instead of tinfoil as it can bake the plants

Im no expert but Clear pots are bad for the roots, this could be your problem.

Lol ok the smaller one is ok now she needed some water. The bigger one is really getting big and strong, the only problem is that some of her leaves are getting slightly yellow and they have a few brown spots on them. My sister is getting a new camera tommorrow so I might be able to post pics tom or the day after. Also I have to go pick up some nutrients for the girls, Im not sure but which nute of the NPK is most required in veg growth? Besides that they are doing grand, and I plan on getting a stronger CFL and adding another CFL so they both have their own light source.

correct me if im wrong but i believe thats right then higher P for flowering and ya do away with the clear pot because roots are photosesitive as well as flat white in place of foil or mylar would be better good luck

You want mostly "N" for vegetative growth, and then you'll switch to "P" for flower.

Like super said, your soil looks pretty rough. Have you PH tested yet?

Also, do you spray the leaves during light/dark hours? I believe that spraying the leaves just after the lights turn of can really relieve som heat/light stress, and although i hear/see people do it, you don't want to spray them during the day.

Krinkly foil will create hot spots, mylar or emergency blankets would be a better bet.

Ok... here are some pics taken with the same crap cam. I have some yellow coloration going on at the tip of the bigger girls leaves with some brown spots near them as you can see in teh pics. This same coloration is happening on a smaller scale to the smaller girl. The soil I am using has some nutrients in it, im not sure if its anything to worry about but the values are.. .15 .05 .10. Could the problem be related to ph levels? Im not certain what they are but id like to know if I can rule that out. Im thinking its either lack of fresh air, (which doesnt make sense as theyve been getting the same amount of air as always and this problem has only started happening recently) not enough nutrients, or too many nutes in the soil. Take a look..









Id also like to know i can top the plants or if thats something you only do when there are buds forming?

The crispy edges and brown spots are from NUTE burn.. looks like your using some SCOTTS soil or something simular with nutes already in the soil, this is not good as a young cannabis plants need no nutes untill about a month old.. When you transplant find you some new ORGANIC soil If you stick with what you have you will be fighting THE BURN till they die...


Also YOu sould consider loseing the foil, this can cause hotspots, at the same time I would also buy a few more CFLs It looks like the one plant is bigger because Its right under the light but the other is turning and reaching for the light put a few more bulbs.. Just remember with flouros you want something LIKE 75w/psf... Have fun and good luck...

Spraying during lights-on is fine, so long as you a) use a wetting agent, so there are no large (magnifying) droplets, and b) have good ventilation.

As for the clear pots, roots don't mind so much; the trouble is that algae and other non-benificial organism will flourish in the moist atmosphere and compete for Oxygen in the root-zone.

Lack of Oxygen in the root-zone is Bad News, which is why you find growers shaking their water bottles like crazy before watering their plants.

ps.. Remove that foil! Even flat white paint is superior.
pps. I have no comment on the nute-laden soil, other than... "Oh dear".
