I have 2 white widows from seed.

can anyone identify problems.

ppm at 1600 with botanicare nutes from stink buds recipe

i had the temperature gauge at the floor and when i raised it to top mid of plants i realized its much hotter there

temp went in to the 90's now everyday i have to leave room open but damage is done. will i still get a decent yield? i have no ventelation cause i had a co2 tank thats is now empty but i leave room open and have fan blowing into the room now temp is at 80-84 at top of plants instead of 88-95.. im think i stunted them

plants went into flower room on 3/13

now its 4/18

agreed with the nute burn look...and now that you got the temps down a bit.as long as they are watered fine.ur good.
id trim that dead stuff off tho..the green looks healthy yet..they'll grow yet..

you dont think it has anytihng to do with the temp... nutes seem to be low compared to stinkbuds formula. he runs it at 2000. i run it form 1300 - 1600 just in case.. one time ppm went to 2000 but i added water and it dropped fast so it wasnt much over 2000ppm it has been creeping up to 1600 from 1300 in about 1 week ph is 5.8

but also since room is open to cool it down my rh has dropped to 28 percent even with a cool mist cause my air is getting blown out.

when i leave room closed rh is about 45-60

hmm 2 ppl saying nute burn.. what should i do.. stinkbuds thread says that blueberry can only handle nutes up to 1700 and ak47 can handle up to 3000 without signs of problems. so he averages 2000 ppm for all his strains and im a nice amount under that. seems wierd to be the nutes as im using exact same stuff he is using and have measured everything when mixing nutes.

just to make sure you guys know.. i had my termometer closer to the plants and it was about 95 for like a week or more b4 i knew.. so i put a 400 cfm fan to blow air into the room with door open so i is now about 78-85 when i do that... also checked the rh and its at 27 percent with room open.. closed is about 50

anyone else think it can be the heat instead of nutes?? they were at 95 for almost a week and kept crisping the leaves till i opened room.. now it seems to stay the same

thats the most definite answer so far... hope my lower nute level helps it out.

gonna try to cut as much brown/dried leaves tomorrow

Nah man, looks like a humidity problem!! Have u got fresh air coming in & the expelled air vented out?
Humidity should be constantly between 45-50%, if it's lower your plants dry out. U should have negative pressure in your grow area, meaning your exhaust fan should more powerful than the intake supplying fresh air.
Anyway here's a thread you can read & mabey it will help. Good luck brobongsmilie

yeah.. i have opened the room to let a strong ass almost dewalt fan.. blow into it so it can cool down.. temps dropped form 95 down to 80-83

humidity was about 45 without a coolmist humidifier with room closed and 65 with the coolmist with room closed

humidity is now at 27 percent with coolmist and the strong fan. can only have one or the other now =( lower heat or better humidity.

Looks like nute burn to me. Most plants can tolerate high PPM levels but this must be done very slowly by gradually increasing the PPM over time. I have had room temps in excess of what you have and I have never had that problem.

its def nute burn bro... heat prob didnt help though but def most of damage is nute burn... and quick question y would u risk contaminating your flower room wit hermies.. i like to roll the dice but intentionally risking pollinating your room is a little nuts

ok thanks.. what im guessing is that i went up in nutes maybe too fast, or non calibrated meter.. and also not enough humidity and too high temps causing all the top to burn like that
