Gorilla Glue (Fastbuds)+ Quantum Boards

WEEK 8 Day 50 - The plants got dry quicker than normal. I forgot to compensate for the new dehumidifier in the grow-room. When I checked today a test pots was only 5.02kg in weight. They were watered with 3.3L each of 75% strength nutrient, with a double strength CalMag additive. The PPM was 950, the PH was 6.9 and the runoff across all the pots was 550-650 ppm. The water was 24c. I noticed what I believe is calcium and magnesium deficiency across the plants, so I did the same strength feed as 3 days ago, but this time increased the CalMag to the maximum manufacturer recommended dose of 1ML/L (I was using max 0.375ml) prior to this. This additive has 2% Mag and 6% Cal. I also bumped the PH up to 6.9 to ensure maximum magnesium absorption. Up until now all my feeds have been between 5.9 and 6.2, and I read the Mag really needs 6.4 and above. If this fixes things then I might start varying the PH of my feeds to ensure the plants get all the micronutrients. I might also start foliar sprays of Cal/Mag. After watering the test pot weighing in at 7.7kg so it took on 2.7kg of weight approx. The fans seem to be working well. I rearranged them to both be on back poles, and for their oscillation to follow that of a pair of windscreen wipers, this ensures all of the plants get direct air movement and circulation. The Dehumidifier is obviously working, and really helping the plants get larger amounts of water/nutirent. The wilt issue is still noticeable but has generally been decreasing since the nutrient build-up/flush events. So I put the wilt down to simply being stressed plants taking time to recover. Overall the growth rates have accelerated massively, and the leaf colours have continued to deepen and the wilt has continued to lessen, and is really only showing during the light cycle on one plant now. I hope this higher PH, higher magnesium/calcium feed will go some way to accelerating their recovery as well. The bud sites continue to thicken up and the plants are looking better every day. I am very happy with the current environment, and the progress of the plants since their difficulties. I also defoliated today, I removed enough fan leaves from each plant to allow the stem and branches of each plant to be seen, so I aimed mainly at any leaves growing inward, and any fan leaves that showed bud that was below it. This has opened up all the limbs to more light and more air circulation. I expect a 3 day watering cycle from here on in, so next watering day will likely be day 15. I might move to 100% strength for that feed if they don't show any overfeeding signs before then. The next feed will likely be at PH 6.5 to allow magnesium absorption. After that I think I might alternate PH 6.1 and PH 6.5 feeds if not implement regular foliar cal/mag feeds. Day 51 - The plants seem to have responded really well to the CalMag Boost and higher PH feed. They haven't shown any further wilting since then, and they seem to all be deepening in colour and their leaves are all standing out without the limp bend I've become so familiar with. I defoliated the remaining plants today, and all the bud sites are now visible and getting light. I am very happy with the current state of the tent and the recovery/progress of the plants now. They seem to be doing well. The humidity is fairly constant during the light cycle at 60-65% and the air temp is hovering around 25-27c and I'm happy with both of these metrics. Day 52 - Plants continue to deepen in their green colour and have shown almost no wilting since the last feed. I'm really happy with the condition improvement. Day 53 - Fed the plants with another 75% strength feed (except CMX at 100%). Started adding silica supplement. Solution details: PH: 6.3 PPM: 1050 Temp: 24c. Run off PPM: 650-800. Volume per plant: 3.5L Run off per plant: 750ml. The PPM of the run off has been increasing by around 200ppm per feed since the plants were flushed. So it seems they aren't consuming all that they are being given. To avoid a build-up and lock-out I will feed at 50% on the next watering. Day 54 - The plants continue to move into flowering and deepen in their colour. They have shown almost no wilting this week. Day 55 - The plants continue to thicken their flowers and to grow more foliage. They are probably due for another light defoliation any day now. There is a definite sweet smell to the tent now. Day 56 - The plants continue to grow well. They could do with a watering today, but I don't have time so it will happen tomorrow right after lights on.
