1st grow - Grandmommy Purple - *Now DWC*

11/20 - 11/26 Week 11 (entering week 3 after cutting transplant) 11/20 - Had to do it. I topped Sawtooth. Hopefully the shoots will grow tall and strong like plant B. At this point I am convinced this branch had 'fasciation' as the stem was flat or like flat shaped. I'm really looking forward to see what Sawtooth does. Now I need to figure out how to slow down plant B so the others can catch up. I think I will have to start training it soon. I'm going to try not to touch the others for a little while longer. Oh also... after some research on DLI and ppfd I cranked up the light to 50% which is 300ppfd / 16DLI. Plants seem to like that but I thought they liked it before so who knows... I'll keep it here for a week. Reservoir change is due for tomorrow. I think I will hold off until 11/22 because I ordered some things to help with draining and filling the reservoirs. No harm in waiting. I have been checking the PH and PPM but not as frequently. The ph was 5.9 all yesterday and it's at 6.0 today. I'll probably adjust down later tonight or in the morning before lights out. Otherwise, everything should be fine for now. When I change the res, I will probably use the same mix of nutes, even the epsom salt since nothing adverse seemed to have happened and the plants all look really good. =========================================================================================================== UPDATE: 11/26 - After the topping of Sawtooth, it recovered very well and the side shoots have easily taken over and the plant is gaining height. Similarly, Plant B, the tallest plant, is responding very well to the LST performed on it on 11/24 to reduce it's height and keep its top level with the other plant's tops. Plant C and D were both topped as well when they got to a good point for it. Both of those plants are recovering well to the topping. I will start training plant C and D soon. I do plan on cleaning up some of the inner/under growth of the plants soon. I have already done this on plant D today and I like how it came out. I want to observe and see how this affects growth for a few days before doing it to the other plants. But they are in need of some thinning out. I ran into issues with the net/mesh bag I got as the roots were easily able to grow through them. So I looked around for a better stitched bag... So instead of paint strainer bags I found honey straining bags and the micron weave on them is much smaller and tighter. It reminds me of rosin press bags. I thought this would solve the problem with the roots but it doesn't. The damned little roots are able to force through and it's a small small micron... Whatever. I have a plan to deal with this. I still like these honey bags better and will keep using them as they stop 90% of the roots. So I will just put something in the bottom of the buckets to keep the bags of the bottom and away from the draining holes. Then I will pull the slack tight on the bags to hammock them over the bottom. The honey bags are shaped much better then the paint strainer bags and work better for this. I may keep looking for smaller micron'd bags or a different kind of solution for this. I mean I have seen roots grow through cloth so I don't think I can 100% stop them. At the moment, I am putting more mental energy into figuring out how to eliminate the 4 reservoir system and make it 1 res for the 4 buckets that drain out of the tent... I have some ideas but I have to start designing.. As for environment changes and reservoir nute info I have made some adjustments. For the res refilling, I waited until 11/22 to do the res change as I ordered some things that I used and were delivered on 11/22. The tap water was 8.1ph and 134ppm. I added 50ml of ph down to get ph of 5.5. I cut out the cal-mag and went full part A. I also tried to keep the ppm down and ended at 534ppm for the res. I think this next res change I will try and up it a little bit. I have also reduced the time between flooding to 2 hours. So every too hours the plants are flooded and drained. 2 mins to flood 5 or less mins to drain. Lastly, as of today, I raised the light up to 70% which puts my ppfd/dli at 350/22 or something. I'm going off memory. Either way I pushed up the light intensity. The light is so high above the plants... I think before I raise the power on the light I will lower the light height cause its like 3ft above them... But it's fine like this for now. Updated the nutrients to reflect what was added for this weeks res. Next res change will probably be on monday. This will be only 6 days but I want to get back on track and also up the nutes as I think the plants want that. Also it looks like I was inputting the epsom salt stuff wrong before?? This makes more sense. I put in 5 teaspoons into 20 gallons and that's .25 teaspoon per gallon. That makes sense cause I should have been adding tablespoons I think. Originally I read 1 TABLESPOON per 5 liters. I am using 20 gallon res, so that's 75 liters. 75/5=15 tablespoons. and 15 tablespoons = 45 teaspoons. I mean... that sounds like a lot. hmm mathematically this works out to 2.25 teaspoons per gallon which is 19% of the total amount of nutes. I think I'll just keep the 3% boost for now and not have any issues about putting in 5-15 teaspoons next res... Did I mention I have no idea what I'm doing? Hah. I feel like I'm making it up as I go. Last thing, I have been pretty lazy about the ph. I caught it on 11/24 at 6.4 across all the reservoirs. I ph downed them to 5.7, 5.7, 5.6, and 5.3. Then today they were at 6.1, 6.0, 6.0, and 5.9. So I ph downed to 5.4, 5.5, 5.7, and 5.4. I say this because I noticed some yellowed/singed tips on new growth in pictures. The ph jumped up fast after res change. I'll keep this in mind next time.
