I haven't had a chance to read all this yet, but I'm going to work on it. My leaves are yellowing and I added some nutes, so I'm hoping for the best. We'll see what happens. Thanks for all the helpful information.

One day I looked in on my vegging p. kush and it was wilting like crazy. I checked the side intake fan and the damn thing was unplugged. Right after that I saw a post of someone's lack of CO2 and that's exactly how mine looked. Make sure you have plenty of air. I know you've thought of over-watering, right? Also, check your temps. I'm looking for info on nutes, so can't help you there.

This lady has been in veg for 23 days and today her leaves are turning colors, not good ones. I'm using Schultz 10-15-10 every water and blood meal (just a little bit every week). From the descriptions on this site I'm thinking Mag and Calcium def. Any advice or comments? PH is right on at 6.5. Thank you.

Thank you so much! Nitrogen def,wish my dumb ass would have realized this weeks ago.The picture in the guide(number 3 I believe) is dead on.I had been trying to use any nutes sparingly for fear of burning in outdoor pots.I'll just step it up a notch other than that everything was going fine and have 5 healthy females this year all started from seed.I'm such a proud papa,just moving in to flowering so maybe one more good feeding.

I really dont understand how people have so many problems, I must be the luckiest SOB on earth cause im terrible with my plants treat them like shit experimenting all the time, I only use miracle grow nutes and not much of that I cut my clones from my previous grow everytime just before inducing flowering and have been using the same strain for about 2 and a half years now which i started from bag seed I think it may be northern lights cause its a fuckin champ outdoors and not bad indoors either I use cfl's for my clones and a 400 watt hps for flower light sched is 18/6 then 12/12 for flower always a soil grow ussually whatever is the cheapest indoor potting soil i can find and Ive never lost a plant yet other than the odd clone but that is to be expected as my cuttings are usually very small here are some pics this grow I induced flower early as i need some smoke before my outdoor becomes ready thesr are about 2 weeks into flower and the clones are obviously 2 weeks old!!!!!! added some outdoor pics 6 plants the same age as the indoor cant friggin wait!!!!!!!!!!!!!!!! ps if anyone can help identify the strain it would be much appreciated. the outdoor ones have been pruned 4 times to keep the height down as I have nosey fuckin neighbours but they are tucked in behind the tomatoes perfectly i think. ps the indoor only had about 4 weeks veg!

My plants have been thriving just fine but I went into flowering so I decided to go with (Growtek) Monster bloom which was recommended by a buddy. The plants were strong as heck until i threw this stuff in the mix. I'm doing complete Hydro, I flushed this nute out and started with new water but still after 2-3 days of waiting for it to fix itself it still has these round dots all over the leaves and some of them are withering and Dying. Can you look at the pics and help me diagnose this problem I would be more than appreciative.

Hello, I'm a first time grower, I have a very small operation just for personal use. I have planted 3 seeds, and I'm having problems with one of them (maybe). I'm using an aeroponics system, so all 3 seeds share the same water. But one seed is grey, fuzzy, but still growing, and has not hurt the other two. When i first saw the fuzz i immediately thought of mold, but i don't want to throw out a perfectly good seed if that's not the case. I have used small amouts of nutrients (1/4 the recommended amount for seedlings). Any information or ideas would be greatly appreciated!
 
This is my first time growing. I planted 4 seeds 1 1/2 month ago and they seemed to be doing okay. On 1 plant I noticed it was getting eaten by bugs so I put this herbiside on it and it seemed to have gotteb better. A couple days after that we had unreal downpoor of rain approx 15-20 mm. So I figured I should hold off watering them for a week. I checked the plant yesterday and noticed the majority of its leafs were gone except the top one and it was sagging a little (it had a slug on it I don't know if that effected the sagging). I did water it a little when I checked up on it. Ill post a pic but its hard to see. I'm wondering if there's anything I can do to save it?

heres a site I found useful- www.1stmarijuanagrowerspage.com. Also for those who like to read, the indoor/outdoor medical growers bible by Jorge Cervantes is packed full of info. I recommend to any first time grower to get a copy,expensive at $29.95, but worth every penny.
