Does anyone know what could be causing this, they end up with brown\bronzing on them and they get so hard they crumble in your hand.
1/ overfert! 2/ ph problem! how often and what fert do you give them?........and what is the ph of the medium? ............Peace out.......Sid
its not a light prob as its happening to the lower leaves not the top. like sid says thats over fert or ph. iv bin havin the same thing cus of a problem with my tap water. i was getting over and under fertin probs at the same time on the same plant. if ur in soil flush the pots and dont feed again 4 a while. when u do start feeding dont over do it. not quite enough is a lot better than a little bit to much when it comes to fert.
Thanks for the feed back guys, I usually feed twice and then flush, my buddy said that he doesn't flush and causes no problems, I guess he's worng. I do check the Ph of my tab water but should you be checking the soil also??? I buy Promix soil. I also just bought a PPM meter, havn't used it yet, do you guys use them???
I think that looks like exactly what sid said. I would just flush and be patient for awile. Good luck on your grow. Post an update on the status! -late
may be a nutrient lockup due to bad water. I have found that leaving out my water overnight or more has really picked up my plants. You may also try and add some EPSOM salts(pure magnesium) to your water. This will probably make a big differance as I had the same problems and this did the trick!!! Good Luck and Peace!!!
i find my water quite weird here......crystal clear, and lovely to drink, straight out the tap.......but it has a ph of 6.0 and when left overnight, it goes to 7.0............Peace out........Sid anyone else get this?
