Take whole plant pics, veg and flower stages are very different.Just noticed this today, mainly towards the bottom leaves but sort of all over. Is this fungal or disease oriented? I do not see any pest either, I checked the bottom sides of the leaves. This is the plant in flower, the veg plant does not have anything like this.

Doesn't look bad, what week of flower?This is the flowering plant.
3 weeks Friday, just wanted to make sure it wasn't something I could fix or a sign of deficiency or pest.Doesn't look bad, what week of flower?
That is an advancing phosphorus deficiency. I stand by my prior advice. She looks hungry. Three weeks into flower, her needs for p and k are going way up. That tip burn isn’t actually tip burn. You would have a little crispy tips. That yellowing on the tips is a sign of potassium deficiency also. Handle it however you like. Growing without enough p and k generally isn’t fatal. It will definitely trash your leaves though and affect flower development.Just noticed this today, mainly towards the bottom leaves but sort of all over. Is this fungal or disease oriented?

So, back to the PK spike ? What's the best way to keep it organic but get her fed?That is an advancing phosphorus deficiency. I stand by my prior advice. She looks hungry.

Yea that's too early to fade, she is hungry I would agree. Calcium too your light be turned up too high. Turn the light down or up their food. To do it organically use a compost tea and top dress then you will be set.That is an advancing phosphorus deficiency. I stand by my prior advice. She looks hungry.

My light is at 24" at 30%, it's a 200w vivosun.Yea that's too early to fade, she is hungry I would agree. Calcium too your light be turned up too high. Turn the light down or up their food. To do it organically use a compost tea and top dress then you will be set.
That's probably fine light wise and the suggestion above worksMy light is at 24" at 30%, it's a 200w vivosun.

Would you recommend waiting until I get some pk in her before ramping up to 75%? Headed to the Hydro store now. Everything else online would be another week before I could get it and I know she's hungry now.for this stage in flower i think you can start giving 75% power, bud will soon start to swell and this is when you want the most light
I backed it down because I had it at 50% but the smaller leaves at the top of the stalk start to twist and tips started yellowing.i don't know at all if it would change much waiting or not.

Vitamin B1 Debunked
The truth is that although research and experimentation throughout the 20th century has revealed that various auxins combined with B1 may help to stimulate root growth, Vitamin B1 on its own does not. This illustrates a classic case of correlation not equating to causation. In fact, one experiment showed that just plain water worked better for stimulating root growth than water combined with B1.
The reason that this myth perpetuated for so many years is that in those original experiments dating back to the 1930s, Vitamin B1 did help to stimulate plant growth in a controlled lab environment; however, these results failed to produce similar results in the real world. Lastly, it’s helpful to understand that under ideal conditions, healthy soil containing certain strains of bacteria and fungi naturally produce Vitamin B1 without the need to supplement with “fortified” fertilizer supplements.
Moral of the story? Don’t be duped by the marketing hype, and skip the B1 fertilizers that claim to ““prevent transplant shock” and “stimulate new root growth”
and this:
Vitamin B-1, aka thiamine, does not reduce transplant shock or stimulate new root growth on plants outside the laboratory
Healthy plants will synthesize their own thiamine supply
Healthy soils contain beneficial microbes that synthesize thiamine as well
So, I visited the local hydro shop and ended up getting some Gaia Green Bloom. I am also considering getting some cal/mag but the shop didn't have anything I really liked or knew much about. I have seen Mr. Canuck use it and his grows always look beautiful. The only thing I heard that I didn't like was it takes about 2 weeks to see the results from the amendments. Not sure if that's a great thing or not because the plants are autos but what do I know? It says it last for 4 weeks but I see people using more often than every 4 weeks. Plus, I can only assume that in the next 4 weeks my plant should be close to harvest.View attachment 2104065
Best bet for au nateral
Some Epsom salt and gypsum will work as well as CalMag. Spread a tablespoon of each on the soil and water.I am also considering getting some cal/mag but the shop didn't have anything I really liked or knew much about.
