plant problems... what's wrong?

1. Are you growing from seed or clones? seeds
2. How old are your plants? 3 weeks
3. How tall are your plants? ~4 inches
4. What size containers are they planted in? bottom 2/3 of 2liter soda bottle
5. What is your soil mix? 20% perlite 10% sand 70% scotts potting soil
6. How often do you water and what type of water do you use? tap water... i allow the water to sit for days to evaporate the chlorine. Also we have a brita filter so it should be decent (although still city) water
7. What is the pH of your water? no idea... will know by next week
8. What kind of fertilizer do you use and what is its NPK ratio? I haven't used any fertilier. The scott's soil has a retardedly low count for fertilizers... 0.07-0.01-0.03 as the regular fertilizer rating (N-P-K)... although is it also time realeased
9. What kind of lights do you use and how many watts combined? 3x 23w CFLs and 1x 30w CFL for a total of 7 plants in a 2x3 or 3x3 area
10. How close are your lights to the plants? not close enough to cause heat stress (plus the CFLs are very cool)... 2-4 inches away
11. What size is your grow space in square feet? 2x3 or 3x3
12. What is the temperature and humidity in your grow space? 70-80F. Idk the humidity but it's low... I have a fan running for ventilation
13. What is the pH of the soil? don't know
14. Have you noticed any insect activity in your grow space? nope..
15. How much experience do you have growing? first grow


Hey everyone. I just transplanted a couple plants into a pre-fertilized time release soil (I know that's awful, but It's all I could find). The plants are about 3 weeks old. One of the plants is having very bad transition period (see attached photos).

This is the entire plant that is suffering (picture #1).

Look closely at the leaves.... all of the leaves initially had very faint darkish patches on the inner leaf area (see picture #2 and 3) before they entirely start to "dry" up and curl inwards... (see picture #4).

Any ideas guys? It's 100% not because it's underwatered...

I don't have the means of measuring the pH yet, but I will soon.

Any help would be appreciated!!

good job on putting up all that info. obviously it is important to be able to check that ph, but unless it was under 4, doubt u would have a problem at this age.
that being said, I would venture to say your plants are just basically hungry. 3-4 weeks old is perfect time to start feeding. the leaves that are twisted like that I would say is a P deficiency, only P will make your leaves twist, roll and drop. also, from that first pic, I would say they are low on nitrogen-overall light green appearance.
time to start feeding,go light, real light, like 1/4 strength at most with every other watering for now than when they recover feed every third water. make sure you have proper drainage and dont overwater.

Any other opinions or did he nail it? It just seems odd to me that only one plant is having this problem... I have a few others already transplanted into the new soil. This is the only plant to display those characteristic leaf darkening splotches near the center of the leaves...

It seems pretty severe to be a P deficiency if none of the other plants are experiencing this seeing as how they're in the same soil type. Opinions? Also, I was led to believe that nutrient deficiencies dont affect a plant so severely and directly, but instead stunt growth and show symptoms... this plant was transplanted yesterday and she (fingers crossed) already has gotten this bad.

Ideas?

dude your plants are hungry-plain and simple.they will suck what they need from these lower levaes first-thus signaling a deficiency. look it up./
