Nute Burn or Heat Stress? With picture

Hey all,

These girls are about 2 1/2 weeks along. I have had trouble finding pictures of nute burn or heat stress on plants this size. Just hoping to get a little input from someone with more experience than I. Pictures are crap, I apologize. There are two girls in the same res, the other has a VERY small amout of light coloring on two leaf tips. This one is light green at the tips as you can see and has a tiny amount of brown starting in the same area. I fed them quarter strength nutrient solution about 5 days ago, temps are high in the tent (with the heat wave it is hitting 88F or so daily. (It vents into the room, as I am in an apt and cant vent out a window)


Any and all help is appreciated. If it's nute burn I want to make sure to get the res changed and rectify the problem ASAP. Thanks.

the end of tips issue is usually too much nutes.

Slight nute burn. Flush and dial the nute back a bit. 88 degrees isnt too bad. Im in hawaii and temps here r in that range. My girls do just fine. However higher co2 levels allow plant to acclimate to higher temps easier. Tropics have a higher co2 level naturally. Dnt kno where u from but normally u dont want temp's over 90 or so.

it actually dont look bad. but yeah yellow tips are usually too much N. in hydro though keep your ph 5.8-6.2. try your best to keep water temps 70-75F. room temps try not to go over 85 unless your running co2
