Hydro SCROG RDWC CO2 600W Mars Hydro

26-09-2021: 3rd week of veg-stage. Great. Will the be the last week or am I going to let them grow another week. I am switching to 12/12 as soon as the containers are not visible anymore. Then I also put the light on 100% power (75 right now). I sprayed the leaves with Hy-Pro Spraymix. Also topped the Runtz Muffin to slow her down a bit. Ladies almost touching the SCROG-net so probably next week starting to SCROG. I like that period on soil. Had no succes on hydro jet so I am curious how this will go. 27-09-2021: Ok.. The growth is good now, it's nice to see how they get a boost as soon as the roots hit the water. 5 cm in 1 night is really no exception. In the meantime, the first Gelato has just tapped it, so topped it right away. Now in doubt... The EC is at 1.1 and as you can see in the diagram below, the EC decreases slightly over a period of 3 days and the PH increases slightly. In fact, this indicates that the EC set is now almost perfect. (In a perfect situation the values ​​remain the same and only the water level drops). So I can go up slightly with the EC and the system is set up in such a way that as soon as the clock turns the EC goes to 1.4. However, I still assume that I am 3 weeks of pre-growth (that is now 11 days) and that means that the EC is still on the low side for 11 days. A low EC ensures faster growth is my experience so far (and is also confirmed by what I read about it). Now I can choose 2 options... continue to grow for a few more days on the low EC and then a little earlier to 12 hours or increase the EC slightly for stronger roots and trunks and then complete the 11 days. The danger of the latter is that they continue to grow quickly and that I will soon have a much too full net (after all, they generally want to grow considerably after the switch). Tough decision. Lighting basically the same story. Now running at 75% and I see nice wide plants with big leaves. Under the TSL, the plants are much more even than under the SP3000. You can see very well that the SP3000 actually hangs above the front row of ladies and that the light does not radiate to the back row. The TSL suffers significantly less from this. I could solve this by hanging the SP3000 a little higher for more spread, but the purpose of this test is to compare. What do you think? increase both lamps to 45 cm and then at 100% or just continue? The danger of raising is that they will stretch more and I don't want that because my net has a fixed height and that has proven to be fine in the past for an even scrog (see also Jack Herer round). I have to say that I can't wait for the ladies to hang full in the net. Daily tying is a very therapeutic activity for me, as is photographing the buds as they begin to take shape. Then I ask for advice on the following... I ordered Green Sensation this week with the idea of ​​adding it from the 4th week of flowering. My nutrition computer can only work on the basis of proportions (in this case 5ml/L hydor A/B and 1ml/L green sensation). However, the bottle advises to dose green sensation first and then adjust the EC. My computer won't do this. I therefore wonder whether I will not dose too little Green Sensation. How could I solve this? (daily manual dosing is not an option because of the recirculating system). 28-09-2021: Refreshed the water, Sunday/monday switching to 12/12. Irrigation turned off for rest of the round so I hope for the little lady that she survives that. Bond First Lady under the net so scrogging is starting now 😬 29-09-2021: Today I snapped the Red Hot Cookies (the only one😢) so moved the little purple Haze in her place. Besides that I decided that it is time for 12/12 so I switch the light scheme 3 days earlier. Hoping that an tiger EC will strengthen them a bit.
