what do you think is wrong with my plant?

have a room with about 25 flowering . im on the 2nd day of the fourth week right now. only two plants are lookin weird this is one of them the other is very similar but lighter in color. the pics are all one plant. my room stays from 75-85 and is usually round 55-68 % its hard to control. im usin ebb n flow for this set up. i dont understand cuz all the others look healthy

well lookin through the plant problem baseline thread i would say looks like a nitrogen toxicity or deficiency. now i thought you want less of this in flowering. and if my plant is deficiant or goten toxic is it possible for the rockwool to cause the plant to go into a lockout i thought this was generaly more prone to soil.

what can i do to fix this if thats what it is? add more N? which i guess since im using gh nutes i would add more micro to my solution??

No no dont add N, they're overdoseing on it already! What is your medium? Just rockwool? Ohhhh ebb and flow...howd i miss that ? lol Yeah just relax on the N and make sure your PH is str8 mate.

some of those leaves look toasted

yea i did have some toastin problems a few weeks ago. i had never used a 1000 before . had no idea they were soo dam hot. but i do got it at a level to where the tops are stayin green. but these tops are just dam weird. the rest of that plant looks great. the other three tops that is. these two look like crap...? i ono. im gunna water them more cuz i was readin n thought maybe that could be it.

more advice the better tho cuz i still dont no. my ph is always very consistent when i make it always settling between 6.0 n 6.1 , is that ok?

Im waterin when the lights come on and before they go off now. I must say im not seein anything improve. May be gettin worse.

1 of my plants is looking very to yours and I'm curious how your plant is doing?

i have plants that look just like this and they are only 4 weeks old, not sure what to do, and i am using ufo lights so it cant be heat, have you found out what it is yet?
