Help plant 8 weeks into flowering has crispy browning leaves....

Hey,
My main issue is the plant in the first picture which is showing signs of some sort of nutrient burn or something. I really would appreciate some help on pin pointing the problem. I am usings Fox farm ocean forest soil which i mixed sith a few parts dolomatic lime during middle veg when transplanted. I used the fox farm nutrient line big bloom, tiger bloom, grow big, open sesame, beastie blooms, and cha ching. I realized last two grows I did that the Open sesame, beastie blooms, and cha ching were to strong for the plants at recommended dosing and so i only use like a 16th of a teaspoons per gallon. For the last week i have been watering with distilled water cut with my home water which has 180-220ppm. I started adding epsom salts at 1-2 tsp per gallon at like 6 weeks into flowering due to unhealthy looking plants especially the tall plant. I read that water with a ppm 180-220 has a lot of calcium and lacks magnesium? So also added some dolomatic lime to the top inches of the soil about 4 tsp per pot. I felt my soil must of been out of magnesium, but i may have been wrong and over dosed them? I also watered like two watering with just plain distilled water then read its bad for the plants since it contains no trace minerals. Take a look at the pictures, all of these plants seem to be odd. The tall one has a lot of nice THC, but droops green leaves. The other two show leaves that are getting brown dots on them and are turning yellow/brown/crispy. The one plant has large buds with lots of hairs, but the calyxes are very small and so there is like no THC as far as i can see with my pocket microscope. I also used Thrive Alive B1-red and GH Diamond Nectar during veg and 2-3 weeks into flowering. I would water every day and every other waterings with nutrients.

I got a Hortilux 400w HPS and like 18 CFL daylight spectrums around the plants. I got this stuff called Omniflect on the walls, apparently its better than Mylar. I have a like 250-400 CFM can fan. The temp is around low 70 degrees Fahrenheit on the floor, but ranges from 77-93 degrees F the closer you get to the HPS reflector. So i use a small fan to blow towards the tops of the plants to lower the temp to 78-83 Degrees F. Its pretty hard to tell if maybe some spots get hotter than others. I position the fan differently some days since it doesnt oscilate. And honeslty the expensive can fan doesn't seem to do much more than a 16$ can fan at the hardware store. The fan blows through the HPS hood into ducting that goes to an attic.


This is my 3rd grow from bag seed, next grow im using stuff i ordered from the attitude seed bank. Anyway Right now I have 3 girls, all are larger than I was going for due to the supper cropping type bends i put into the plants. They are only in 1 and a half gallon pots. There cant really be a bug problem as i used Mosquito dunks in a bowl of water and anything that drinks from it dies. Also i watered the top few inches of soil with mosquito dunk water during veg (Mosquito dunks are a compressed poison powder put in water used to kill larvae). I also dont really see many critters flying around. I had a buddy take care of my plants while i was in Europe for 2 weeks during weeks 4-6 of flowering. My buddy is a little slow and may have overdosed some of my plants i also had 6 then and discovered immediately when i got home 3 were hermaphrodites and harvested them. Actually toking on one now its not bad if u get the seeds and nannas out. Probably gonna make bubble outta it.

Ill name the pictures or something so you know whats what when you respond.
Please let me know if you think it is a nutrient problem or maybe even the light is to close? Though they weren't showing signs of heat stress for a while even when they touches the HPS hood.

Gonna have more pictures in a half hour, the camera battery died, recharging now hehe.

Please help

Thanks everyone.

Couldnt figure out how to edit my post on this site, anyway here are some more pictures. My dang camera battery isnt done charging so i just used my phone. They are kinda bad b/c the HPS messes with the phones camera.

One and a half gallon pots seem awfully small. If plants are in to small of pots they can get rootbound and simply can't get the water they need. I had a plants get so rootbound I had had to water it three times a day to stop it from drying out. When you water them does the water immediately run through the pot and out the bottom? If so they may not be able to absorb the water and nutrients because their is no place for the water in the pot.

Here are some more pictures of the damaged plant. Please someone post a reply.

Yes i realized they are probably root bound, but it is to late to transplant in my opinion. Its strange the tall one was draining water immediately when i got home from Europe. Now its holding water and the one with the crunchy leaves is draining water and it was holding its water pretty well just 3 days ago. Also the one with little to no THC holds its water fine and its also showing similiar symptoms just not as drastic yet and has 2x the canopy of the one thats really drying out. The top few inches of the soil seem moist. At most i have to water once a day or every other day. And i just started watering the tall one and no THC one once a day b/c the top inch of soil was dry. The most sickly one was still moist. Dang its so hard to tell what this is. I hope my PH test kit will help. And yes I wish they were in 5 gallon buckets i bet this wouldnt of happened. I read that the root system should be atleast the size of the cannopy, and even in a 5 gallon bucket my canopy is way bigger. Hopefully next time i wont veg for 8 weeks and super crop snap twist the plants as much so they stay more petite.

Think i could like squeeze the pots to loosen up the root balls? I heard garden nurseries do it, but they are ussually hardier plants.

Thanks for the reply.

umm...dude. Its time to harvest pretty soon here. Looks like with this strain your leaves are dying and then getting crispy due to the heat in your room.

Crispy can happen...but, your buds look fine. I would harvest now....Just my opinion! :thumbsup:

If being rootbound is the problem you could place the pots in buckets and fill em up with water and let them soak for a while and then let them drain. Be care ful about standing water and humidity. Humidity that is to high can lead to bud rot. I check to see how dry a plant is by lifting the pot and checking the weight and water accordingly. It works for me but I've had practice at that.

BTW, never have someone watch your shit when you are out of town. Simply do not go out of town during flower time. Your plants did get burned...but, some of this is due to heat with the normal nitrogen die off in your leaves.

In the future use the form please. I had to add that otherwise I would not be totally helpful to the rules! :D

Thanks and will do. Im gonna try to wait it out a few days before i harvest i think. If it gets any worst ill have to i guess.

good day:)

id chop ASAP as the dead leaves will attract mold to those buds man.


i chop now!



peace and love
