Picture 1164.jpgPicture 1172.jpgPicture 1170.jpgPicture 1173.jpgPicture 1167.jpgThis is my second year growing outdoors.I have five white rhinos and three sweet tooth. A few weeks ago i started to see my leaves get very yellow with brown spots through them. I grow in a soil less mix and used jacks 20-20-20 for vegetative and jacks blossom booster for flowering 10-30-20. The plants are in there third week of flowering now. After seeing this get continualy worse i did a ph test which was fine and checked the nitrogen and phosphorus and the nitrogen was real low and phosporus was a little low. i bought some blood meal 12-0-0 to fix the nitrogen it was that low and i also got some superthrive and mollasses. I applied that to them three days ago and i checked them today almost half the leaves on all the plants are getting yellow with these brown almost burnt looking spots but worse of all today i realized it is starting to go right into the buds i can't figure this problem out i have tried practicaly everything these last few weeks but nothing seems to work. The pics that i'm posting are from a week and a half ago they are alot worse now i have been picking the leaves off not sure if i should be doing that or not. The pic in the bottom left is something new i haven't seen that before there not brown spots like the leaf is burnt or something idk hopefully this will give you guys enough to help me out thanks

I not sure bugs or mold. I'm probably wrong. Just trying to rule out...Don't pick off leaves that still have green.

I had a hideous mold just before harvest on first grow.
 
pick of all those yellow leaves cause the plant is using its energy up trying to fix the yellow leaves so it can get sunlight, but you want it to use its energy up on budding. hope this helps
 
Looks like it could be a nutrient deficiency to me, you have a lot of yellowing going on.


On the other hand if you've made sure they are getting the right amount of food maybe they aren't getting the right amount of water?
 
Looks like the soil is no good for growin may be to acidic locking out nutes. Water it with some bat gauno tea and next time dig a big hole and put some good composted soil, bat gauno,bone meal,and dolmitelime in it. Are those pine trees layin there? Soil around pine trees is no good.

well its a soiless mix predominately perlite and peat moss. Its all dug out and filled with that mix. I know now i should have put some wormcastings and bat guano mixed in for added nutrients but i never did. So are the pine trees still a big deal if i did that? I grew four plants last year and they came out beautiful there i just don't get this hope i can get this figured out i have a bad feeling my hard work and time is gonna go down the drain and my plants r gonna die.I will post a rescent pic of it going to the bud soon. Thanks alot to everyone that has given me some insight hopefully with your help i can save them. I appreciate it guys.
 
Well it rained hard here the last two days but this problem has been going on for some time now its just getting worse and worse and now going to the buds.Not sure if me adding the blood meal and superthrive with water then getting all the rain the last couple days could have made the problem worse with getting so much water at once. But i know that is not what caused the problem just wish i knew how to fix this.

Peat moss has no nutes and has a ph of 4.5. and pine tree soil is also acidic thats why i'm thinking its bad soil and last year did you use the same mix?
 
NITROGEN DEFICIENCY!!! Buy the horticulture bible, great asset, buut im positive its a nuit deficiency
 
This is a little clipping i took because it was going up to the bud you can see right next to the bud looks like its burnt or something all brown the leaf right under that has two brown spots on it. If anyone has ideas of what this is please let me know. Also you think i should clip the leaves and buds that are showing signs of this or leave it and try to fix it.Just dont wanna leave it and have that be the reason its spreading if its a disease or something these plants got me lost.Picture 1158.jpgPicture 1159.jpg
 
You think the spots and everything are just from a nitrogen deficiency? I havent heard of an n deficiency causing that. I tested everything a few days ago ph was around 7 the nitrogen was very low so i bought some blood meal and put that down but i think it takes some time to kick inbecause i checked n level again and no change i also put super thrive and mollases down.
 
ph is 7. I"m sorry to be a newb but what is ppm? My nutrient schedule i used jacks 20-20-20 and my plants grew great through vegetative i was more then happy with them right before flowering they gradualy started doing this i went to jacks blossom booster 10-30-20 but only used it once so far because the problem was getting so bad after that wasn't sure if that was why they got so much worse so quickly. So i have only used that once. I normaly only give them nutes once a week and a nice dose of water. I got desperate realized how bad my nitrogen level was got some blood meal and put some superthrive and mollasses on it just hoping that somehow i would see an improvement but there just getting worse i'll listen to anything at this point just wanna save them

No actually i didn't use a soilless mix last year you think that could be the problem? I use regular potting soil last year. But like i said in the vegetative stage the plants grew way faster then last year in the soiless. Another thing is i had one rhino in an organic soil and that plant looks the best by far was the smallest plant in the beginning so i changed the soil to try the organic and now is the most healthy out of the bunch but even that one is starting to get it to slowly but surely so idk if thats what the problem is.
 
So with the added pics what do you guys think? Also can anyone tell me the fastest way i can raise the nitrogen level dramaticaly obviously the blood meal was a stupid idea.

You could try a bat gauno tea mixed with worm castings which is high in N.

First prob should go to the store n grab some spring water at least. It should have a much better ph than what you're using. I had some spotting and browning like that with some leaves dying completely. I use FF Happy Frog Soil with a bit of extra perlite and I had only been using plain water until then tho so I started giving it some of my jacks 20-20-20 and it's developed lots of new growth, all of which is nice and green. All the growth that was damaged hasn't repaired itself and I read up that it wont ever fix itself. You gotta be patient after you give it nutes. You won't see the effects until like a week. Just give it a watering until you have like 20-30% runoff with 1/2 teaspoon/gallon. Jack's has a lot of nutes in it. Read the side. It has magnesium, calcium, iron, nitrogen, phosphate, and plenty more. It gives the plant a little of everything. Be careful on how much you throw into the soil. Keep it simple with a base soil like fox farms and let the plant tell you when it needs nutes.
