First grow ever

Day 28 Epsilon f1 measured 40cm, Siberian haze 38cm Both doubled in size in one week. Temperature went up to 28deg C today so I opened up the vent holes in the tent to control the climate I think I wil relocate the tent to a cooler space so the vent can suck in some cooler air so the climate wil be more controllable. Other then that noting worth mentioning Day 30 Seems like the ladies are more thirsty then I thought, they let the leaves hang a little bit, So I took some action and gave them some extra water Day 32 They seem to appreciate it coz they look happier then a few days ago 😅 I’m glad it didn’t affect the growth I measured them today and epsilon f1 is 48cm, Siberian haze measured 50cm By the color of the hairs I must say they are 2 good looking blondes 😝 I did notice some yellow spots on some of the leaves, not quite sure if I should be worried about that Someone knows what this could be and how to fix it?
