Help! Lower fan leaves drying out slowly at the tips and edges. Doesn't look like nitrogen deficiency to me, but please prove me wrong!10 days ago the lower set of leaves started drying out (they get brown not yellow). They don't receive light, but now it's already started showing on the third set of leaves. Does it look like nitrogen deficiency or can it be something else? Just gave it full strength nutes.5y ago

Deficiencies? Brown spots, yellowing and purple stemsWhat is this deficiency or maybe toxicity and whats the solution? She is fed with biobizz chart instructions but with every other watering. She is big so I'm guessing I should water with nutes every time? She showed this first week into flowering.5y ago

Brown rust spots on oldest leavesBrown rust spots on oldest biggest leaves with curling inward - the rest of the flower is fine, just some occasional small yellow spots. No sign of pests. Maintaining pH ~6.5 but have soft water. Suspect cal/mag deficiency or nitrogen toxicity. Thoughts?9mo ago

Cal-mag issue that won't go awayI keep getting a cal-mag deficiency. I have been using 1ml per liter of water - 4ml roughly per gallon. It is only 1 plant, the same which has had the same cal-mag issue since early veg.
I include cal-mag every watering and nutrient feed day.

Calcium deficiency?I recently bought Calimagic for my calcium fix. Prior to this week I have been using tap water for calcium. Is 2mL/gallon of calimagic too little? Noticed some leaf damage I believe to be calcium deficiency.
Does she need more calmag?
Thanks for your help all!Week 8
