please advise..29 days into flowering

ok here are some pics im in day 29 of flowering,thes are white rhino,noticed that some foliage is getting brown spots,,then after a few days are yellow,with some sort of blak burn,there are some pics posted,,i was foliar feeding as soon as lights cam on,,but ive stoped,im using earth juice,bcuzz bud booster,and fish emulsions,,it started at center of plant and is going up from what i can tell,is this normal at this stage of flowering,they are in 5 gallon pots,,water when they feel light,,using 2 400 hps,they are about 10 inches above tops,got intake vent, oscilating fan ,and exhaust ,fan

i think that there is a slight overfert(nitrogen) and a little heat stressed,never mist when their flowering, they may get burned when the light's go on, or get moldy,raise the lamp's a couple of more inche's,12" distance above the top's is ok,go easy with the nute's,you really dont need any nitrogen when they are budding(or very small amount only)youll be alright....bonbon

it may be too much magnesium, i dont think the nitrogen is playing a role, and 12 inches away from the plants is way too far, especially with 400 watts. My advice is back off the nutrients, and flush it for a couple of days till it gets better. Also, your plants may be too small for that 5 gal bucket, so make sure to give them little amounts. what seed co. did you get your white rhino from, if the leaves start getting yellow and crusty, give the plants a straight shot of pure N.

these are couple of informative page's, http://www.overgrow.com/growfaq/1111 http://www.cannabisculture.com/articles/2428.html ....bonbon

are u using an enclosed reflector, along with the direct exhaust blower? cause if so you can put the light even closer, but nothing less than 8 inches. My 1000 watt hps is about 10 inches from the top of my plants, and i have never had any sort of burn form the intense light or heat, but my reflector is encased, and i have a blower specifically for the light. Along with fans pushing the heat away from the plants. But if you dont have an enclosed reflector, it would be best if you kept it 10 to 12 inches away.

if its your bigger leafs then its totally normal man, its apart of the growth process. Well if they are dieing super fast then somthing is wrong. But if its a slow process (about 1 leaf a week or so) then I belive to be natrual.

Sorry but I wrote more to it and couldnt edit it :(

But if its a slow process (about 1 leaf a week or so) then I belive to be natrual. But I wouldnt discount nute burn either becuase that does look like mag. over nute problem. Also yeah dont mist, the water droplets acts as a magnifying glass and will burn your plant. Not to mention the plant wont gain anything from the water like that, it is now using all the stored energy and nutes from the leaves (hence the normal process).

And yeah dont use hardley any nitrogen, but use high phosphate. Go with 10-60-10 and that should work fine.

I have seen this before many times and i have looked into it. Never mist your plants. I have found from research that THC production in a cannabis plant is for two reasons. the first reason for THC or resin is to capture pollen from a male cannabis plant and the second reason is to prevent the plant from drying out or dehydrating. If 2 and 2 are put together 4= the less moisture in the grow space, the more THC produced from the plant. i personally have only grown indoors 2 times and Never once misted my plants and the results were a great heavy stone because of the extra THC produced from the plants. I may be wrong and it was just good genetics but i highly doubt it. sorry if i sound like a know-it-all prick. P.S. Your white rhino looks GREAT. keep up the kick-ass work. :D
