+5 strains

I am a first time weed grower but few years of chili growing experience and I don't want to be cocky or arrogant but just want to give friendly advice. So I'm growing the same stuff in drip feed/ebb & flow combination system and its funny to see that you are struggling with deficiencies while I'm having toxicities with same strain and both hydro grows. Check my diary 'cos I have been documenting my pH and EC pretty good and you can adjust yours with those and maybe this could help you with your grow. What I see from the pics, I think you need more nitrogen (maybe 150-200ppm overall) and you could add epsom salt 1 tsp/l by foliar feeding every "dusk" or "dawn". My experience with epsom salt (Magnesium sufate or MgSO4) have been really good and I have been giving it to my girls once a day with fulvic acid and this really helps with the yellowing of the growing parts. Also the cupping of the leaves is the same I have so I think your heat:humidity ratio is off in your tent for this strain, maybe add humidity or lower the heat ( Wet towel to bucket does the trick for humidity). Mammoth P gives you plenty of phosphorus for your grow as long as you don't add it yourself too much. With Mammoth P you can have bioponic system and you don't have to add so much of the base nutrients but you need to provide food (Simple sugars for example, dextrose, fructose, xylose, molasses etc.) for the bacteria so they can transfer the food to nutrients.
TL:DR Raise your EC to ~2.0 with more nitrogen and maybe epsom salt and give simple carbohydrates to bacteria and let the bioponics do their magic. Also coco coir will suck Mg and Ca out of your water so you need to add it more than usually.
