Would love if anyone could help

View attachment 2794418View attachment 2794481Hey everyone I have a few feminized sannies seeds: Kolossus in early veg and the new growth seems to be doing well but older leaves are wilting and dying off. I kinda feel like it's nitrogen def. but would like more opinions before I go adding things to it. The roots receive the nutrients (lucas formula) via misters and am us r.o. water. Temp is a bit warm but everything else seems to check out. If you need better picks please let me know, and chime in if you have any ideas please
ps sorry for all the scattered pics

hydro ? water to hot over 70 f ? looks like stem rot to me in the beginning stages. its trying to get water and no luck, are the roots correct looking white ? my advice is if you are hydro and over 70 and cant get temp lower, throw it into soil,

any warm temps in hydro you will get fungi . root rot, molds, fucked plants, if you check the water it looks good now and in as little as 2 hours the damn plant is dead , happened to me in a cloner,

Yeah hydro water is above 70f do you think I could lower the temp enough to save it?

Yep, , , , GET THOSE WATER TEMPS DOWN!!!
You still have a chance, But remember that ANY hydro in the summer not just should but MUST not go over 70 deg F. For longer then like 4 - 8 hrs as root damage WILL happen fast in many breeds. Yeah some can take the heat and silica and Co2 can help heat tolerance, , , but, don't count on that to carry you through!

An air temp of 70 is prime,,, but in Hydro, , ,root temps can be critical. In DWC you can help make things better by doing a daily top off of 30% nute add back.....If you do 10ml of nute "x" to make a full strength solution, then make "add back" solution at 3ml and so on for all your nutes and supplements! Keep feeding back till the TOTAL amount of the "feed back" is the same as the amount of a full "starting" tank (as in aero) or bucket. Then dump and refill with fresh , full strength nute solution.
Supplement your room cooling if you can to stay around 70.
Put frozen bottles of water into your tank to help cool down during high heat times.....helpful but not a solution! (root shock from cold can happen if "tank" is small)

During the summer I only run soil grows to avoid this whole problem...I mainly run organic soil grows. But do run DWC and soil org/synth durring the colder months to achive specific goals.

Good Luck

Thank you all very much, I really appreciate the help. Ill keep this updated to see if I can keep em living lol thanks again
