D 120. Fed. Spec A is doing alright. She has started to show deficiencies again. I think there may be a ph problem with the soil. Spec B is still very beautiful and healthy looking. She has also started to show deficiencies through the middle. Spec C is very beautiful and healthy. She isn't showing signs like the others. After testing the soil all 3 were very low on the ph side of things. D 121. Watered. Added baking soda and dolomitic lime to soil. Will add some calcium carbonate to try and bring it back in range. Spec A is doing alright still, when I watered her I drenched her good. Hoping a good flush will raise the ph and get some of the base additives down lower. Showing signs of flower now. Spec B is doing good. Flushed soil. Starting to show signs of flower. Still very healthy looking. Only inner leaves that aren't getting much light have been affected so far, not too worried about them. Spec C is still looking the best, starting to flower now. Very big and beautiful. Tons of huge tops. I will continue to flush for the next couple days. Hopefully I can get it under control. I think it is partly due to how close together they are and the duration of nutrients so far. Will cut back to 1.5 ml/l, during flower time and on water days I will give them a good flush. About 8 weeks to go. Hoping its salvageable at this point. I am going to switch their feeding schedule also to try and help cut down on nutrient buildup. F.W.W.F.W.W.D. Nutrients will be added at 2.5ml/g, for the first couple feedings. Then up to 5ml/g starting next week. D 122. Watered. Spec A is hanging in there. Still doing good. She was flooded today. Spec B is still doing good but is starting to to show a bit more. Also flooded her good. Spec C still healthy and beautiful. Not really showing much signs. Flooded her as well. D 123. Watered. Added calcium carbonate to soil and water. Hoping that helps bring ph back up. Spec A is doing alright. Deficiencies have started to slow by the looks of it. Not loosing as many interior leaves. Spec B looks pretty good. Her symptoms have seemed to have slowed down a little. Not seeing as many yellowing leaves. Spec C has not really been affected as much as A and B. She has not slowed down and is still gaining height. She under went same soil conditioning as A and B. D 124. Fed. Switched to bloom nutes. 2.5 ml/g. Ph of solution was 7.3. I usually lower it but since its rather low under the soil, it may help counteract the acidic ph problem. Spec A doesn't look too bad. I'm hoping to see an improvement over the next couple days. Spec B was still looking pretty good a few yellow leaves through the middle. Hoping to see some signs of improvement over next couple days. Spec C is just a beast of a plant now. She doesn't seem to be bothered with low soil ph. I just hope she doesn't get affected like A and B. D 125. Watered. Foliar sprayed with velokelp and magnifical. Been leaving the yellow leaves on in hopes to slow the spread. Spec A is still holding on. She continues to bud so hopefully it can be corrected and produce some nice buds. Spec B is doing good, very green still. Think problem may have slowed. Left leaves on that have been affected. Spec C is still great. She is huge, not been affected much. Beautiful. D 126. Watered. Thought I may have had soil ph problem under control but its not looking good. Spec A is slowly cannibalizing herself. She has a lot of mass to her still and the tops haven't been affected yet. So maybe she will produce something but the soil is being very difficult and at this point I'm not too sure if she's gonna pull through. Spec B is starting to cannibalize herself now. She still looks very healthy and huge but it looks like its slowly spreading. Spec C has now started showing signs through the middle. She is a monster of a plant though. This has been a stressful week. I've tried everything I can to correct the soil ph. They are all way to big to try and transplant. At this point I'm just stumped. I don't know if maybe they are not getting enough water for the size of them. They all get 4 litres of water but the surrounding soil in the area is made up of mostly clay and it hasn't rained in weeks, so its really dry in the yard. Spec A is well over 7 feet tall I'm hoping that the overall mass of the plant will help keep her alive until I can figure out a solution. Spec B and C are well over 9 feet at the tallest point. FML.
