Problem with plants in the 3rd week of vegetation.I'm posting again because I accidentally marked it as resolved. I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.

At what stage do leaves get darker ? This is confusing I overwatered them at the beginning of veg and then I fed them with 0.7 ec nutes max, EC would go up if I gave more. I've had tips burning probably from light too close. I find that leaves are pretty dark but it may be because of the strains. When leaves do get darker in flo ?

Black marks on leaves of a slow grower.Noticed there's black markings on the edges of the leaves on our slowest growing plant. My initial thought was water droplets sitting on it before it had fully broken out or could it be something else?

First time DWC, day 70, 3 weeks in flower. Nasty rusty spots appear on lower leaves. Is this CalMag or else? Please help understand and fix, thank you :)I'm using TA Tripart, current EC is 1.6 - ph 5.5-6.5. Everything was smooth until week 10. Two weeks ago I started adding Plagron Power Buds and Green Sensation. Yesterday added CalMag to see if it helps, but it doesnt seem to... She drinks a lot, ph mostly goes down, EC static
