Auto Strawberry Gum & Power Plant XL Aut

After butchering them last week with having the light too low, giving them nutrients too soon and making up for it by adding unbalanced RO water my plants, they now look like this. They will pull through but are quiet stunted. Thanks to the people on this site I could quickly diagnose the things I did wrong and correct them right away. Big thanks to the people who answered my questions! Now the light is at 70cm (around 30 inches) from the plant since Tuesday. They have grown a lot since then. For the last 2 days I've started to add nutrients back into the RO water and balanced it around 5.8 to 5.9. Earlier this week I just went with bottled mineral water with a ph around 5.8. Ive given them a little bit more light this week due to the fact the night cycle was getting a little too close to 10°C (50F). Now I have a small heating in the room with the tent so I can try to keep the temperature around 15-16C. Next week I will try to return to the 18/6 cycle. Outside temperatures are going up so I should be fine. I hope all these plants pull through and become big and strong over the next couple of weeks.
