Black Cream Micro Soil

Day 36 - gave a feed/watering with Biotabs nutes. They recommend 20ml Orgatrex and 1ml Bactrex in 500ml water, once. I did a half mix, and put the same amount into 1.2L so it's not too much for the little plant. Watered this in slowly and got a little bit of run off, which the fabric pot soon sucked back up. Looking nice anyway. Day 37 - noticed some discolouration on some lower fan leaves. not sure what to make of it, doesn't look like typical lower leaves dying off as the plant grows. not too concerned yet, but I will keep an eye on it. Day 40 - gave a nice big drink, about 1.5L of water with alg-a-mic at 3ml/L. Also did some defoliation/removal of lower bud sites. As this is quite a small plant, and vertical growth seems to have stopped, it seemed a good idea to nip off the buds that will underdevelop with the aim of promoting growth at the top bud sites instead. Went fairly heavy (in my opinion) on it, hopefully she won't get too stressed. Likely the final time she'll see the snips until harvest. The buds are developing nicely. Lil sis showing some signs of the light being too much for her, moved her lower down in the tent to let her recover. She may be toast though, seedlings are so delicate. If she doesn't look better in a few days I'll start another. Maybe in a slightly larger pot. Day 41 - looking nice today. some lower leaves starting to lose colour and die off. Day 42 - another week wrapped up! The buds are looking great. some weird discolouration still developing - if anyone has any idea what this is likely the result of please let me know. I am thinking possible calcium deficiency or else maybe a disease like rust. Unclear, but I'll ask in the grow questions section and maybe someone can shed some light. I can easily add some CalMag to next watering if it is cal related. Baby plant looking... ok. Still growing. We will see what happens. The plan for next week is to continue as is. I will continue to water with plain water, and maybe another Orgatrex/Bactrex mix towards the end of next week. I will likely utilise some PK 13/14 at some stage - never used the stuff so not sure on how to best approach it. Overall I am pleased with the growth of the plant this week. The buds really smell like hash. At the moment the light is at ~675 umol, giving me a DLI of ~48.6 running on 20/4. This is about as much light as I'm comfortable subjecting this plant too. It will stay at this level for the next two weeks (ish) and then begin to turn back down for the ripening stage. I'll keep an eye for any signs of heat stress in the interim. Thanks for reading!
