Nitrogen overdose?

week for 4 of flower little preflowers showed but all the pistil coming out or dark brown with very little to no trichomes.. I am using 4x4 tent 1000w light 3 gal pot soil using roots organic full line and following there master feeding schedule, please help its has stunted there bud growth tremendously there are about 3-4 plants of the 15 that are fine there little prebuds are alot bigger with big long white pistils and alot more trichomes... And to add i have been cutting my own clones no males here

thats not a nitrogen def. Nitrogen def will turn the leaves a really dark green and the ends start to claw.

it looks like your plants actually NEED a little nitrogen.

what is your ph like? yea it doesnt look like nitrogen tox to me either. what kind of soil are u useing you didnt mention and i think i know why

sorry it took so long to get back was at work...i wasn't thinking im lacking nitrogen i was wondering if it could be from to much nitrogen also i was thinking maybe heat i keep my room temp around 70-80 the best i can but on some of these hot days it hard to keep down but it has hit 95 a few times but if it was heat i would think they all would be the same but there's 3-4 that are fine an look untouched but anyways i also keep my humidity between 35-45%. and i am using a roots organic soil and readygro mix, i pH check the water every time using the color changing drop thing and adjust up or down to roughly 6-6.5 the best i can match the colors hopefully im not color blind haha my water is usually water from the dehumidifier or rain water i try not to use tap water if i do i like to boil it and i mix my water and nutrients in a 5 gal bucket that has a pump on the bottom for water flow an mixing and another pump that bring the water from the bottom to the top for a good mix and so i can stick the watering container under it lol and then i have two air pump to aerate it. i really haven't watered them with just straight water till i saw the brown and curling leafs they have been feed nutrient solution since day one of 12-12 here is a some more pics hope fully this helps figure it out

2 issues here , 1- too hot must be under 80 ,get cooltubes next grow, will more than double your weight. 2- Pots too small causing yellowing from root system and moisture stress.

if its heat why aren't they all brown, is kinda why i wasn't thinking heat so much that and i have had it hit 90+ last summer and this never happened, oh and i dont have a cooltube but i do have a air cooled hood, i have a a 6in 400cfm fan sucking air out of the room thru a carbon filter a 4in 300cfm pushing filtered air in and a can fan about 150-200 cfm to cool the light, i switched to the three gall about 3 runs ago cause i had 5 gal. but they got to tall for my room and cause i couldnt get the pots to dry out good enough this three gallon and mixed dirt have been working well for me last run was great

Agree and no add ons from me.

They look like they need N, P, K, Ca, Mg, possibly S, Fe and Zn. They look starved. I don't see a resounding endorsement of that nute line (either that, or its implementation) in this example. cn

they defiantly are not starved they get watered a nutrient solution everyday and each run i am adding more and more nutrients till i see them burn which is what i thought this was
