help newbie here leaves curling up \ turning yellow

okay after having gone through 5 guides here is my setup i have a 25 w cfl 125 watt cfl which produce total of 20000 lumens which is what i need right now for vegetative growth. here is the problem initially the growth was slow so i added the 125 now i am limited by space the temp intially was 25 then jumped to 45 so i added a fan and cooled the area the temp then came down to 18 and is now back up. as a result now my leaves are showing signs of curling and yellow color coming up on new leaves. what do i do ? pic 2 and 1 were suppose to be at the same level of growth but 2 is doing better then 1 y? 3 well . that plant is in its own world . each of the planets were started at the same time yet some are growing faster then others y? a lot of the guides don't cover this so i ask.

You should get a fan to blow on them. I can't see the side of the cup, but you might check to see if it needs repotting. Check your soil Ph and wait until the top third or so of the soil is dry before each watering.

okay so this is happening to 1 of the planets now and you were right over watering was the issue what do i do with that leaf simply cut it off ?

Just leave the leaves as they are for now. Many problems affect the bottom leaves first and you might as well let them happen to the damaged leaves first. Make sure any problems are taken care of and that the plant is growing healthy before removing them. If you haven't yet, check the Ph of the soil.

hi guys so everything is on the good i had to force them to flower 10/14 day/night. they have the white folicles coming out so i am just wondering how long is it going to be ? they started flowering about a week ago. i have it figured to about 2 more weeks. i have looked around and i guess its different for each plant but a general guideline and can it be possible to harvest in 3 weeks exactly. i will post pics but for now the flowers r only 1cm tall.

Flowering time varies drasticly with strains. There are plants that take as little as 6-7 weeks and there are Haze strains that take almost four months. Size also plays a part in flowering time but 3 weeks is a very short time even for small plants.

then i have a problem cause i am moving out in 4 weeks and i am away for a week. anyway i can speed up the process?
