This is my first grow. I feel the box is too hot sitting at 27/28 degrees and min is at 23-24 (when lights are off) Should i add an extra intake fan or do i need to upgrade my exhaust fan to remove heat? The leaves on the green crack turn upwards. while the heavy hitter is looking nice (to me ) can someone advise what to do here? Is this just the heat? I am using Terra Professional soil which i will change to terra coco on my next grow. Ive only done 1 shot of nutrients so far and that was a week ago. Planning to do another on Sunday for each plant. UPDATE: Hi all, thanks for commenting and the advice. Ive written a little update / summary answers to all comments below. I will upload further photos of my grow box. and yes it is a minish grow box (is a full size fridge) but here are its contents. - 1x 6" exhaust fan - 330 M3/Hr - 45dba (this fan is too loud so im going to replace, up for recomendations) - 2x80mm 240v intake fans - 52.8m3/hr EA - 35dba - 1x6" carbon filter - 2x6" clip fans (internal fans) - 2x80mm pc fans (internal fans) - 1x 300watt LED light ( 2 internal fans) 1) my humidity is actually 70% i was wrong writing 50%. does this mean the heat is the main issue for the leaves curling? the light is at 40cm so i didn't really want to lift it anymore. 2) I will start to water the plants in the morning as that is when the lights are off. i will continue watering 500ml-1l every 2-3days depending on the soil dryness on top and the weight of the container. 3) i have just used about 3.5ml of terra veg nut and 1l of water yesterday per plant. is this once a week ok or should this change? 4) any advice on altering PH ? i feel I cant get the technique right. i use ph down anyone have recomendations on how much PH down to use per 1l? my water i use is pearu pure water thanks again! is reassuring some aspects are good.

Yes leaves are curling up from too much heat. Spraying with the light on could worsen the condition creating more heat on the leaf surface so stop that. If you spray when the light on you need to add a surfactant like gentle soap otherwise just do it before lights on or just as it goes off. Can’t really see the setup much as you only have a few pics. I can see it’s a micro grow. I’ve done a few micros in the past. Heat was always an issues especially when I lived. If you could get yourself a 4” RVK fan and some tubing you could put it on the outside of the box. My guess is that this will help dramatically. In reply to your watering. You should try and water the whole medium I soil especially canna professional which is great IMO don’t water with too much run off and keep your nutes 1/2 strenght till the 6th week of use in the soil. Then do a flush and go to 2/3 or full strength as most of the nutrients will be spent in the soil. At this stage your watering seems to be on point. Wait for the soil to dry lift the pot it will seem light then water it. I will follow along as I like a good micro grow!

Yo yo Bro inMyOpinion: Ur grow temp perfect for day time grow but wen it comes to nite time in ur flowering exspecaily u need to have control over ur room : Add exstra fans inside ,upgrade the exhaust start by what u knew must happen. I would get em on sum WormJuice/batGauna or a Good fish Mix like BioBizZ.👊
