Aloha From Hawaii

[Hapaguy]

Aloha everyone! Long time reader, first time commenter. I've been an outdoor grower off and on since around 1980 here in Hawaii and decided to try my hand at indoor growing during the short season. I bought an AC Infinity 5x5 with AC Infinity EVO8 5x5 light. I'm growing in soil (a mix of Hawaiian soil, Fox Farms Ocean Forest, and vermiculite) for the first run since that's what I am familiar with but I also bought the Growace Aircube system which I will be trying out later after I get the hang of growing in a tent under a light. I have my light set to static height (all the way up) and using a light meter to check ppfd which I adjust on the EVO8. For my first run I am growing 4 Cherry Limeaid from ILGM which I am also growing for the first time. For nutes I am using Fox Farms Trio (Grow Big, Big Bloom, and Tiger Bloom) and Cal Mag. I ran 18/6 for veg (ppfd of ~ 600) without any problems and I've been running the tent around 82 degrees and try to keep the humidity down between 60-65% which is difficult in Hawaii. Then when I switched to 12/12 for flower, 3 of the plants started getting weird symptoms like wrinkly leaves and burnt looking pistils on the early flower (see pics). I checked ppfd and the tops were at 650 so I dialed it down to 550. I also turned off all the fans because I saw some comments regarding windburn. I open the tent during the day now to minimize temperature swings because another commenter said temp swings can cause that problem. Anyone have the symptoms in the pictures and have a cure? Could it be genetics, or a disease? Any help would be greatly appreciated! MAHALO for reading!

Temp swings and low temp cause lettuce leaf toughening. I have some this run because I didn't have good heat at first. It made a cool color fade effect with N salt burn because of it, theoretically cost a little weight. Otherwise, if you fix the conditions it still makes the ATP.

Nice work!

Thank you so much for your input. Gotta be temp swings then because I live in Hawaii and we don't really have low temp. It did reach 62° the other morning but that's unusual and not the norm. Usually in the winter the average low is around 68° in Honolulu. In the tent it was still like 68° when it was 62° outside. Because it's warm during the day here, the temp in the tent is usually in the low 70's. During the day the temp in the tent can reach over 87° so I put a portable AC unit in there but it's not very sensitive because when I set the AC unit to 78° it swings wildly from 74° to 86° so I stopped using the AC unit. Now I just open the tent all day and zip it up when the light turns off. Hopefully this helps and the buds can form normally.
Mahalo again for your input. It's greatly appreciated!

Mine corrected and are happy now. They just look like you should be reaching for amendments lol.

The yellowing is actually a "color tattoo" kinda. The only symptom is the edge burn but again... nitro-salt killed it. buds are stacked and bracts haven't even swelled nor has a hair turned.

NICE! What strain is that?
