Hi Buddy. Does the plant you are growing have purple in it's name? Then you can expect that it will have some purple on it's leaves. Your plants look fine and the leaves look fine. there is no browning or wilting or dry spots. Yes, you can expect this from a plant with purple in it's name. Hope it makes big buds for you. Chuck.

What's going on with my clones? Do not have much information to add. VPD is not terribly off, DLI around 25.What's going on with these clones? Not sure what it could be. They could possibly be rootbound. They should have been transplanted a few weeks ago but I did not have the space.

Why is the new growth turning purple?Is a night time temp of 15degrees the cause? I can't keep it up without making it too hot, or could this just be a phosphorus def.? I fed her well yesterday and yet to see any difference, as far as I can see this isn't typical for the strain

So closing week 7 now and my 4AM are showing signs of deficiencies again. I watered(with nutes) ph'd around 7 past few times and the runoff has still been ~5.9, indicating acidic soil(nute lockout)?At this point, you think it's best I just flush with plain tap water(ph ~7.7)?

The insides of a small number of future bud sites are showing some strange purple discoloration. My initial thought was that this could somehow be mold however under the microscope it is very purple. Any ideas or suggestions would be greatly appreciated. (see images week 11)

Should I harvest early? Light stress, leaves browned and dried out, buds are all amber pistils So this plant has been suffering from light stress for the past two weeks or so. I have removed all the dry and brown leaves. The buds still seem fine-ish. Should I just give her the chop early and save what I can? She's been flowering for some 6 weeks.
