First Grow - Point out my faults plz :)

Day 64 - DD starting to get cloudy trichomes now. Buds slowed in growth I believe as deficiencies showed unfortunately, believe the deficiency has progressed slightly but it’s not been long since I changed the nutes to what’s detailed above, it should stop around a day or two from now maximum. Maybe sooner with coco and frequent fertigation - SAH trichomes not popped yet, looking good otherwise - CC got some slightly lighter newer growth in areas with more trichomes coming by the day - Got rid of grow nutes for both CC and SAH and boosted bloom to 8ml/5L of tap water ppm 50 and reduced calmag to 2ml/5L. This should decrease Nitrogen much further and bloom notes have plenty magnesium in them to sustain the loss. Micro has 6% Ca so I’ve been wondering if I even need the calmag? Just use it because everyone does - DD is also heavier than the other two when I water them, so she is now drinking less. Saw a couple of amber trichomes dotted about on top but maybe 10% cloudy. At least a week or two left, lower buds need some time, maybe a split harvest?? Day 66 - I’m positive the deficiency has stopped now, will up bloom soon to make sure plenty is given! - SAH leaves have started to become darker with a blue tint like the other two, maybe due to some bloom deficiency but it’s been happening for a while so the change of notes I’ve given it should help her out! Day 67 - Small brown spots appeared on CC upper leaves, I’m wondering if it’s too much P or K? Reduced CC nutes to 2.5ml micro, 5ml bloom and 3ml calmag. ppm is around 350 now and I could see some tip burn so this should sort it! Might just need barely any due to her height! - DD deficiencies have definitely stopped progressing, just gotta keep her right till harvest! Some foxtailing going on on on the buds I think, will get close ups soon. Maybe from high temps, tent canopy has been hot last few days but that’s sorted now - SAH got trichomes coming in slowly. Still worried about the twisted growth. It’s pretty smooth and rubbery feeling but buds are growing fine so I don’t know, no other signs. Some lower leaves have yellowed from what I assume is lack of light Day 68 - Still watching CC, the nute change should be coming into effect now. Her buds have started popping through the pistols as they swell and they have pretty colours of purple and orange. Won’t get much bud from her bud they’re looking tasty! Should be around 20g yield I guess - SAH growing well, buds are growing quickly with more pistols by the day - DD buds are fairly dense feeling but not huge. Not dense colas either but nothing to complain about for what will be my first harvest! The heats have been higher than I want in the tent which could be what’s inducing slight foxtailing on buds now. Nothing to worry about too much, can’t do much about it as the growth in the tent is quite dense. Got a 5 inch exhaust and fan but there’s just too many plants Day 70 - All good today, nothing to say
