Not sure why but she is showing either magnesium, calcium, or potassium deficiency. Do you agree? My PH is 6.3 this water, and was 6 the last sprinkle I gave her.

Nutrient Help possibly needed
For my first grow I have kept things fairly simple. I had issues with my soil PH which stopped nutrient uptake but seems to have now resolved that for the most part. Are there any other nutes that are recommended to help bud production or am I ok with what I have now? Thanks

Leaves burn
Hi! Is this nutes burn? Damage is on the upper/middle part of the canopy on very few leaves, but many more have black tips. I’m puzzled because during veg I was feeding the plant higher ppm than now and never had a problem!

Help needed - harvest time?
Hi, I'm now in week 12 and I feel that after the flush my 2 vertigo stopped developing. They also have a lot of leaves with some mag issues. Not all the pistols are amber (70%). Also, the trichomes are not all cloudy. I'm not sure but I think I don't see changes anymore.
