Beginning of week 8. Deficiency? Nute lockout? Normal for this stage of its life?

First of all, don't believe the hype the seed banks give you about how long a strain takes to harvest from seed.... they just want to sell seeds and will give the best case scenario.... Second, you've got a calcium deficiency at the very least but your diary doesn't give me any information on what nutes you're providing... the pH looks good so it's not that that's causing the deficiency - it could be you're giving too much nitrogen and this has locked the calcium out... or, since there's no nute info, maybe you're not giving her anything at all in which case I'd tell you to get some calmag into her along with a PK booster (I see signs of other deficiencies coming up).... Good luck.
