Guava Runtz Auto closet grow

Timza Day 7: After sprouting they streched quite a bit, so I decided to top up the soil in the pots. I'm using just a regular household humidifier to control the climate and a small usb fan to strengthen those small stems. Slowly bringing up the watering volume and I've been giving them root juice to develop new roots and calmag to prevent deficiencies. Water 500ml Ph 6,2 Temp 26c RH 65-70% VPD 1.16 DLI 16 PPFD 300 Cycle 18/6h Light distance 50cm

Timza Day 14 I'm actually quite impressed with these. Great vigor/growth rate and very tight internodal spacing, just how I like it with autos. Secondary branches already starting to form, which is also great. I bought a pair of cheap moisture meters to monitor soil. Less of a guessing game from now on. I've been carefully handwatering them with plain PH'd water mostly around the edges of the pots and trying to avoid overwatering. So far the soil has not been fully saturated yet. Gave a small boost with 25% dose of Advanced Nutrients Sensi Bloom A&B on day 10. Water 500ml Ph 6,2 Temp 26c RH 65% VPD 1.16 DLI 25 PPFD 360 Cycle 18/6h Light distance 45cm

Timza Day 21 Absolute madness. These plants exploded after giving them 1 liter bottom watering on day 15. Very impressive growth/vigor compared to autoflowers I've usually grown. Fan leaves are massive, looking 100% healthy and side branches are developing nicely. Also preflower pistils are visible now. Gave them second feed on day 18: top watering with 40% dose of Sensi bloom A&B about 450ppm. They're now almost 20cm tall, so I need to adjust light distance and intensity for the upcoming week. Water 1000ml Ph 6,2 Temp 26c RH 65% VPD 1.16 DLI 32 PPFD 480 Cycle 18/6h Light distance 40cm

Timza Day 28 Wow. They just keep going and plants now completely fill the grow space. Watered 3 times this week and watering volume has gone up to 1,5 liters. 50/50 top and bottom feed each time. I also had to raise the light intensity and height several times. Nutrient dosage is now up to 75% so about 750ppm. Some leaves are showing a slight clawing, but I'm not too worried, because there's no burnt tips. Stems and side branches are healthy green with no visible reds, which indicates that phosphorus level is in right range. I'm guessing they're already in preflower stretch, because height has doubled. Tips of the branches are now growing in zig-zag pattern, so I know the plants are going to flower soon. Water 1500ml Ph 6,2 Temp 26c RH 65% VPD 1.2 DLI 30-45 PPFD 500-750 Cycle 18/6h Light distance 30cm

Timza Day 35 Stretch week. Plants have grown significantly in height and I'm soon running out of vertical space. Really liking the even structure of this strain. Some of the top leaves have slight signs of light stress (serrated edges), but I'm not too worried about it and prefer to deliver proper amount of light through canopy and I can see lots of bud sites forming. Continuing to water top & bottom and nutrient dosage is now up to 100% of recommended, so about 1050ppm. No nute burn on leaf tips yet. First time seeing the roots grow through the fabric pot. Top dressed with fresh worm castings halfway through the week to keep the soil active. Leaf color has been a bit on the darker side and a but bit dull greyish and some lower leaves are showing early signs of phosphorous deficiency. I've been looking into this problem online and came into conclusion that is actually magnesium deficiency, because it is central element of chlorophyll molecules and also phosphorous carrier inside the plants. Even though I've been giving Calmag, but today I decided to add epsom salts (2,5 grams to 3 liters) to plain water and see how things develop. Water 1500ml Ph 6,3 Temp 26C RH 60% VPD 1.3 DLI 45 PPFD 900 Cycle 18/6h Light distance 25cm
