EasyBud RQS MarsTS1000

Day 36 from seed: 36-->40 cm, 390 PPFD, 25.6 DLI. Leaves were praying with the first light. She started stretching again with high speed, about 2-3 cm overnight! I guess this is the result of switching to 18/6 from 20/4. I wonder what I will see in the end of the day. She's very tall already. I hope the flowering starts soon, otherwise I will be out of vertical space when the stretching is over. Busy checking lots of grow questions about slow preflowering autos. Many growers say flipping to 12/12 can work well, and the harvest quality is even better in the end. Four lateral branches are almost the same height as the main stem. I still see new preflowers on each internode, but they just coming in pairs, not packed. That makes me think I've got wrong seed with supressed autoflowering gene. Thinking hard about flipping to 12/12 if no flowering sites appear on day 38. One grower pointed that the plant has dark green color on the bottom, I agree. I think I was giving too much nutes with each watering without giving plain water even once since week 2. It's slightly intoxicated with Nitrogen indeed. Next watering with no nutes, only CalMag. In the evening about +1 cm height. No changes in the way it grows. Still a pair of new leaves with a pair of pistils every few days. Was almost going to flip it to 12/12 tonight, but changed my mind. Gonna wait few more days and see. Day 37: 40-41 cm, 400 PPFD, 26 DLI. Almost no stretching during last 24 hours. Cut off the damaged blades from the fan leaves affected by CalMag deficiency. Checked the soil moisture by finger, a bit dry, also weighted the pot by hand, it became very light, almost 2-3 kg less. Watered in the evening 500 ml pH 6.7 with no runoff to avoid wilting as happened last time. Calculated the previous ratio: 12,5-7,5-22. Changed the ratio of the solution to 6-5.25-11 in order to force her to use some Nitrogen that she's storing in those dark-green leaves near the bottom. Applied 0.5 ml/l Micro, Grow, 1.5 ml/l Bloom, 1.5 ml/l CalMag, 0,75 ml/l Voodoo Juice. Will continue watering on day 38. Will definitely flip the light to 12/12 on day 40 if no signs of flowering appear on day 39. Really weird pheno. Day 38: 41-->44 cm, 400 PPFD, 26 DLI. She was a little bit sad in the morning, asking for water. Today I decided to give 6-5.25-11 and increased runoff. 5 L of solution pH 6.6(6.5). Runoff 20% with pH 6.5(6.4). Stretching continues, new leaves, new branches, new pistils, but they're now asymmetrical. I'm not sure if it's a sign of flowering coming soon, or it's just the sign of plant becoming mature. Luckily I have some grow space. The pot is standing on a rack about 30 from the floor. She's asking for more light, but I need to fix the issue with low Mg and high Ca in solution. T.A. CalMag has only 3,9% of Ca and 0,7% Mg. 1,5 ml/l CalMag brings 58,5 ppm of Ca, 9,9 ppm of Mg, and 15 ppm of N. I'm trying to find the best feeding bloom recipe for her using the available nutes. Attached the photo of different variants, any feedback will be highly appreciated! Day 39: 44-->48 cm, 430 PPFD, 28 DLI. Huge stretching continues. More asymmetrical new growth can be seen. More pistils. Some signs of flowering eventually. Waiting for the end of this week to see the difference. Fingers crossed. Day 40: 48-->51 cm, 450 PPFD, 29 DLI. Installed additional 120mm fan for better circulation. Gradually increasing light intensity. Will add Epsom Salt with next feeding to compensate the lack of Sulphur and Magnesium in the new recipe. I cut the grow component to get the NPK ratio with higher P. Day 41: 51-->55 cm, 460 PPFD, 29.8 DLI. Today I clearly see the beginning of flowering. It's so revealing after few weeks of waiting! The seed from RQS is good. My doubts are gone. 😇 Luckily I didn't flip to 12/12. Current schedule of 18/6 seems just perfect. The only thing I can't understand is why she's sooo big! She will be at least 1 m in the end, while I didn't allow unnecessary stretching. Well, at least it's an auto and flowers are on the way. Applied a new feeding recipe with Epsom salt in it. Should've add 5 ml of concentrate, but added 8 ml by mistake. Good that it was not too strong and it will only give extra 10-15 ppm of Mg and S to the solution. According to my calculations 1,45g of Epsom salt per 5 liters add 28 ppm of Mg and 37 ppm of S. The suggested amount of 1-2 teaspoons per gallon gives too much ppm into solution, I don't wanna risk. Runoff about 25% today. First 400 ml went out quickly with pH not far from solution: 6,3 drain, 6,7 solution. But as I continued watering slowly, pH of runoff changed significantly to 6,2 or even 6. That's interesting. Seems I didn't allow it to flush thoroughly last time by watering too fast. I hope PH Perfect part will do it's job till the next watering. By the way, the finger method of checking soil moisture doesn't work completely in my case. Fabric pot dries evenly from all sides and when just two cm of the surface seems to be dry it means the plant is already too thirsty. Weighting the pot by hands is much more informative. She is sucking water like a pump now, about 1,3 liters per day. Day 42: 55-->59 cm, 490 PPFD, 31.8 DLI. She's good. I'm almost out of space in the closet. Will have to remove the shelf soon and put the pot on the floor. That's extra 30 cm. Recalculated the recipe again, next time I give her 11,5-10,5-20 (NPK as N, P2O5, K2O): about 115 ppm N, 45,15 ppm P, 166 ppm K. Water consumption increased. Watering every 3 days now. Some problems with humidity above 70% during the day due to the weather.
