Cannabis Troubleshooting

I'm growing in Coco. 6 weeks in Veg. COGr Nutes. ph=5.8. Plants are generally healthy, really green with plenty of new growth. I'm a bit concerened because some of the OLDER leaves are showing signs similar to nute deficiancy. They are turning brown and crumbly on the edges. It's only on the leaves that were from the original mother plants when I took clones. What am I doing wrong?. Should I be worried?

How do I get rid of these little buggers and their larvae in the soil ? Will they hurt the plant at all ?

Something went wrong!!

Hi Guys ,, I am having problems with my babies . I am hoping someone can help me . I normaly grow in perlite but have changed to potting mix and am having these probs here and the harvest has really gone down in weight . As well as what you see in the Pics I have some little black flies in the cupboard . I am using Thrive as the Nutrient , PH is approx 6.5 using one of those cheap probe testers . I never used to have probs in the Perlite , I only changed as it is hard to get where I live . http://img.photobucket.com/albums/v411/coach1/Potprobs001.jpg http://img.photobucket.com/albums/v411/coach1/Potprobs002.jpg http://img.photobucket.com/albums/v411/coach1/Potprobs003…

hwdy. regular reader, but need help. started my first indoor soil grow. goin great, but have the tips of some leaves curling down and the leaves feel pretty dry. My first thought was the light was too close. so i put that up higher. Reading through the archives it could be an iron deficency. To help that, the info. says to set PH to 6.5. But doesnt say to set the water to 6.5, or check the soil ph. If I add water adjusted to 6.5, will that adjust the soil ph to 6.5??My first soil grow so kinda wingin it. Ta guys..

Does anyone know whats causing this. Im using Miracle grow soil. XD The Ph was 4.5 i used hydrated lime to raise it and thats when this started happening. Bottom leaves started to die off first and now the bigger fan leaves are going. I plan on flushing it tonight and repotting in a 5 gallon bucket with some new soil.

hey got some plants under 400w just repotted into good organic soil. the first set of round leaves are starting to yellow. and so are some other leaves. any ideas ? ill post pics tomorra

I havent used hydroponic nute on it just miricle -gro at the reccomended rate .Its about 10 inches under a 1000 watter on a heat pad .The roots are nice white and healthy looking , COuld it be too wet ? I just put a fan blowing on it gently Do u think this could be the problem. It shits me because this was only female from 10 seeds .
