Bottom Leaves Have Problem

Hello,

I am first time grower and my plant is 3 weeks old. My poblem is bottom leaves are getting yellow and edge of the leaves are getting brown. Also new little leaves have got same problem which can not be seen in the picture.

There are 3 days between taken photos.

I am using soil mix (perlite, soil etc) I dont use any nutrients. I have one 100 watt cfls lamp and approx 10 cm away.

Dou you have any idea?

Thanks.

It looks like time to start using a weak nutrient solution next time you water. Looks like a touch of nitrogen deficiency.:)

actually my soil has got some NPK but It's really a little. Do you think that it can couse of heat. :(

I did but unfortunately the bad ones are going to. Do you recommend any other?

I agree with loafyboy, looks like a nitro. deficiency. I don't see how heat could be a problem, with just one cfl. Remember that even if you resolve the problem, the affected leaves will probably always look weird.

how is it looking now after adding the nutes?

Nute issues or too little lumiens. Also if thats the 3rd week it seems to be growing slowly. I'd try not wattering so much and get rid of the tin foil

ok i add enough nitro. I will keep inform you about the yellow leaves.

I agree that she has got growing problem. My lamp is about 5000 lumiens dou u think slow growing is about that?. What is you advice with lamp. add more cfls?

I also get rid of the tin foil but I just wonder why?

Thanks for helping me folks.

hi,

these are updated pictures. now she is growing. u have any updates?

I just want to ask a question for advanced growers. I want to mix soil but i havent got any idea about how much percentage add the elements. In my state I only find these metarials below.

GARTENGOLD SUBSTRATE 2
Peat Moss
Perlit
Hydroton

Thanks.
