Day 22: Humidity is dropping to 50% at times under the metal halide but I’m not too worried as I want to start dropping it coming into flower. Plant look far better under the more natural looking light. Whacked it up to 600w for the first 6 hours of lights on today. Not a mark in sight on any of the leaves and the new growth is starting to push up from the bottom. I’m hoping that by the end of the week the plant will have reached the netting that I put up when they where seedlings. If not I will lower it to their height for the start of the pre flower so I can spread them out as much as possible. Noticing massive growth on the lower parts of the plants the metal halide is doing it job nicely. I have tucked the new fan leaves under the old ones to reveal the nodes and I’m start to bend the stem clockwise round the pot. All the leaves looking really healthy and the new nodes, growth is becoming rapid with major changes every time I check the plants and they’re far easier to feed than photos due to requiring less nutrient.
Day 23: Added a .25 of natures candy to the nutrient mix. Usually I would charge my coco with worm castings and feed nature candy the whole way through but my local hydro shop didn’t have any of the stuff I use in stvock when I was mixing the medium for this. 🤦♂️🏻 The main reason I’m doing it in veg with no microbiology in the medium is so the Dyno Myco I top dressed and mixed in at the top has something to feed on if it works. I know that using Dyno Myco as a top dress isn’t ideal but I couldn’t get my hands on it until about a week or 2 after these girls where started. Also threw an air stone that I had lying around from an old dwc set up into the reservoir to oxygenate the water a bit.. don’t know if it will have much effect in a drip system though? If anything it’ll help with mixing.
Day 24: Added a new timer to the drip system and have set it to run for a second watering schedule so the plants will now be watered twice a day. First time being just as the lights come on and second time is 30 mins before lights off. Due to needing more water I have replaced my 10L reservoir with a 30L one. The new nodes and lower growth are exploding. On one of the plant the stem has split in the centre slightly and I’m not sure if this happened while I bent it today or overtime while it’s been getting pulled down already 😅 I’ll keep and eye on it and be a little more gentle with this one for the next week. I’ve already noticed that she was the slowest grower so hopefully it doesn’t slow her down. The other two are really growing well, not much bigger than the slow girl but they are showing better reaction to the LST. I’d say by this time next week they’ll be twice the size 💪💪
Day 25: The plants are really growing , which is getting me excited to hang the HPS. At the beginning I will be using my Omega 600w HPS with super lumens with an air cooled tube, for the pre flower and mid flower. Then when i move the photoperiods from that room I will need the ballast back for my flowering room. At this point i will hand my 250w jmaster blaster HPS and hang my LED beside it. Equaling around 500 watts with UV for the last weeks and the ripening period.
Day 26: Stuck another fan in the room to boost circulation. There isn’t a single bit of the room where you can’t feel a breeze. Because of the extra air flow I’ve lowered the light to 40cm above the top of the plants. The lower nodes are starting to develop more and push their way through. Continued with LST, plants main stems are really strong and can tell they have deep roots.
Day 27: I have noticed that the plants are beginning to show their pistols so I have decided to mix up the pre flower feed (.5 of full Remo range, will be logged in next weeks diary and not next week as what I have logged is what I fed the majority of the week) and flush it through the medium so it can start getting ready to stretch over the next couple weeks. Re bent the tops down, the lower growth have finally nearly match the height of the main node. While bending the plant at the back of the room I accidentally snapped a leaf off from the top node, hopefully this doesn’t cause to much stress. Over the next week I will continue the training and will begin to lower the net and start scrogging.
Day 28: Has been a pleasure vegging these auto flowers and they have reacted brilliantly to the LST. First time implementing drip irrigation and I’ll definitely do it again though some equipment upgrades are required as due to what I’ve been using I have had to manual control the pumps at times. Today I stuck a couple of plastic boxes with holes drilled into the lids to catch the water from the irrigation runoff. Changed the time of the irrigation to as the lights come on, and then 3 hours before they switch off. The plants sitting on the boxes are now level with the net so as they stretch i will pull them through and spread them accords the net. Due to them becoming level with the net I will lay off the LST. End of week 4 and no signs of any stress or burn, they are all thriving in they’re environment. I will re hang the LED tomorrow and hang it above the photos and move these to one side and stick my HPS above them. The spectrum of the HPS will help the plants stretch more during the pre flower stage.
