smalltimestarted grow question 4y ago

Is this dark bluish tint to the leaves an issue? It is only on the the main stalk, She otherwise seems very happy.

I would say to add a little more cal-mag and keep your grow at the same rate or slightly less than previous feed. The coco unless buffered with cal-mag will battle the plant for it resulting in the upper yellowing. The extreme darkening of the leaf almost blue looking is a nitrogen excess. happy growing!

N or P deficiency?Need help to understand if this is P or N deficiency. It's on the lowest fan leaves, one is more pronounced than the other, and it's mostly on one side. Stems and veins look like they're giving hints of P def but from what I searched leaves look like it could be N def.

Discoloration and Spots I'm still not sure if this is a deficiency or some sort of burn. It's definitely spreading a bit more, and I'm unsure if there's time left to address it in the grow. Video of full plant in week.

Yellow and purple leaves I stopped feeding beginning of the week because I had yellow tops on one of my buds. I think it is causing yellow leaves. Does that sound correct? Also I am seeing sort of a purple colouring on some of the leaves. Is that okay?

Is it time to flush? , could I benefit fade from flushing at just the right timing?When a plant genetic says 8 weeks. Does this mean 8 weeks and chop. Or 8 weeks and flush. I'm still confused as this is only my 2nd grow. reason I ask is I'm experiencing a lot of fade. Ihave kept my ppms very steady. So I'm sure it's not deficiancy creating this at week 6

Hi Growers, my tent has recently hit some low temps at about 15 degrees lights off, I have now improved the temps by a few degrees to about 17 at lights off. Purple is showing on my stems probably caused by cold but purple also showing on the back of leaves? Should I worry?

Two problems in a week. I diagnosed the first one based on similar grow questions (: maybe not right )First three photos appeared a week ago, I decided that it is calcium and took a more reliable Ph meter, maybe not right, but no new spots appeared. Second problem at the end of the week, 3 days after defoliation 2 large lower leaves and 2 leaves inside. 30 hours after watering.

Only one plant has these very purple stems. It’s almost every large fan leaf. I’ve read that it’s a nutrient buildup or something? I don’t PH my water which I know is bad but any guesses on what is going on?
