checked my plants this morning and noticed 1 of my plants has small brown spots, in the middle of the first fan leaves, on both sides... i've read through my cannabis grow book, through the deficancy list but none of them are close enough??? Does anyone know what it could be??????? Will upload pics in a few mins
dude, could be lack of water or lack of Co2 im pretty sure that you've been watering it unless u have an automatic system and it isnt working properly, im gonna look into it with my older bro, if anything hell know ill pm you with wat it can be or post
Got it, check if theres any fungus on the stems if there is you need to kill it, but i dont know how. or its not getting enough nutrients hope this helped you out
Ok, i checked my plants and the 1 with the brown spots look different than the rest. She has alot of very dark red "veins" up her main stem and side branches..... and the brown spots seem to be getting worse, and the leaves with the 'brown spots' are getting 'crispier' ... ?!
Sounds like what it is too me, maybe mixed with a little overwatering. I'd shoot an e-mail to Chuck@420ganjaheaven.com or hop over there, and ask daChuck, he's a grow god.
Check my journal out here http://forum.grasscity.com/showthread.php?t=96088&page=4 If they look like those spots, I'm pretty sure it's a heat issue.
can you upload the pictures... also can you answer these questions please are you using soil or hydro? what ph is your soil or hydro setup? if your using soil what mixture or brand is it? what water temps if you are growing hydro? what are your ppms or EC? what nutes are you using how much and how often? what part of the plant is affected? what size pots are these plants in and how big are they if growing in soil? seeds or clones? Strain? lighting and wattage and distance from the plants? temps/humidity? how often are you watering?
