New leaves light green help! Pic

BGAL · #1 04-17-2008, 11:09 AM

I have been growing for 2 weeks now and the new leaves are much lighter than the first two. I read in the Guide for diagnosing that Zinc is a problem but its only two weeks old! everywhere on the forum say you dont need to worry for first 3 weeks?
Please someone help, gettin really attached to these things (the other ones a tad retarded it seems, can post pic if want)

If its any extra help, the first week i pretty much made every mistake - temps in 100s and over watering.

Indoors grow, 400w Grolux Dual Spectrum Lamp, 18/6 light cycle, Temps between 75-85, watering (water a day old) once every five days when soil is pealing from sides of pot. Soil is Reduce peat compost (bag says great for seedlings and indoor plants - well it would wouldnt it...). Cant tell PH yet, getting Kit ASAP.

The strain is dynamite BTW.

It started so well

new growth often starts light green and will darken out just go with it and dont change anything drastically

Unless you are in a hydrohut, I wouldn't worry too much about it....I have run the gambit of yellowing problems, staritng in a damn hydrohut and beyond, and my ladies are doing fine now. Temps will also effect color of new growth. Try to get temps as stable as possible, definitely without serious fluctuations, as they will discolor from that ( I know from experience). Here is a link I love to share, which has helped me alot.
International Cannagraphic Magazine Forums - The Complete guide to Sick Plants,pH, and Pest troubles!

Wow that was quick. Cheers both of you, am less worried now. The temps are fluctuating alot but will be sorted soon when i get the extractor delivered.

That link is brilliant btw, by far the best i have seen so far!

Will keep a beady eye out.
