Can you wipe off the white on the leaves?

If you can, it can very well be a fungus.

But if you cant, then it looks like it has a nutrient deficiency or it's too close to the light

Hmm, well I checked a site on deficiencies, and i really didn't find anything that looked like your leaves.

Heres the site if you wanna check it out.

Or here's one I just looked at - http://www.weedfarmer.com/cannabis/tables_guide.php

You said it's lower yellow leaves, so it could either be a deficiency of nitrogen, phosphorous, potassium or magnesium.

I know this doesn't really give a clear answer as to what you should do, but maybe you can google what to do if you have one of these deficiencies.

My guess would be an environmental problem like high heat low humidity or inadequate ventilation/air movement. Check those factors and see what could be improved.

no temps never above 80F... humidity @ 55-60% and i have 2 circulation fans going 24/7 in a tent 110cmx65cmx160cm and my extraction is also running 24/7 at 195 CM3 on a 400w cool tube... so environmentals cant be the problem

@ sludge factory from what i can gather it looks like it could either be a MG deffiency or over feed on nutes...what a vicious circle...ive got superthrive coming tomorrow would that help?

I've never used superthrive on my plants, but from what ive heard is that it's pretty good stuff. It has vitamins in it, so i'm sure that in a couple uses of it, your plant will be just fine. Its nothing to really worry about imo, i've had worse! lol.


Nice plants btw, i've been wanting to grow LSD for the longest time :blsmoke:
