2x2x4 First time grow

We have reached day 28 and she is progressing well. On day 24 I noticed a split in the main stem where I supercropped her.About a half inch split,so I tapped her up and gave her some more Lst. Much happier with how her shape looks now. Really opened up the bud sites. Also showed her sex this week and we have pistils growing each day. Also increased the light to 100%,went up 1 notch each day,and she responded well each time so I kept increasing it. Other invironment changes were decreased humidity a little and reduced light cycle to 18/6. Temps here increased this week and I struggled to keep the temp in the range I wanted. Day 22 1-15 light 80% Tent 78 humidity set at 62%-54% Light defol Removed most Lst Day 23 1-16 increased light Intensity to 85% Tent 78 humidity set at 62%-54% Watered 1.5 liters Light defol White pistils appeared Day 24 1-17 increased light Intensity to 90% Tent 78 humidity set at 62%-54% Noticed split in stem,put tape on it Resumed Lst Day 25 1-18 increased light Intensity to 100% Tent 78 humidity set at 62%-54% Light defol,4 leaves Lst adjustments Day 26 1-19 light 100% Tent 78 humidity set at 62%-54% Watered 1.5 liters Day 27 1-20 light 100% Changed light back to 18/6 because of high temps Tent 78 humidity set at 62%-54% Defol some bottom fan leaves not getting light Day 28 1-21 light 100% Tent 78 humidity set at 62%-54% Happy growing everyone
