Marks on leaves

Autogrowzstarted grow question 6y ago

What are these marks? Soil grow. It’s on some of the leaves 3-5 inches down from top. Ph is correct after adding food to water. But soil ph is low. How can I fix this and what is it? Thanks.

The mark's are likely ph related. To raise use a little dolmitic lime at a time, until your runoff comes out where you like. Can get at most garden centers. Cheers

My plant was "overwatered a bit" and as a result, it got a whole bunch of brown leaves. However, the buds look pretty good. There are now, especially some sugar leaves, that have a mix of brown, green, and a slight bluish tint. I'm kind of worried that they

It looks like my plant is dieing! Plants turning brown after intense watering period Did I drown my plant? Stress it? I gave a lot of water in a short duration of time, and now 7 days later she is looking terrible! Read my diary on week 17 for more info!

Too much light or other deficiency Too much light or some other deficiency? I’ve been having some issues with yellowing leaves and some other issues with browning and wilting/curling which I thought was initially nutrient lock but what I noticed is all four plants were not stunted and continued to grow normally.

Response to Weezy Hi @Weezy90, the left ones are indeed the Purple Punch. So straight water now for the last week/2 weeks? The one on the right is the NL and is 2 weeks behind the PP's so I'll lower the nutes on that one. Thanks

Phosphorus def in veg?Phosphorus deficiency in wk 4 of veg? I noticed a few small discolored blotches on lower leaves 2 days ago and today it is a lot worse! Use flora trio, and 2 other plants in this run are under same conditions with same nutes. Could this be a pH issue? PH has been consistently ~6.

So in the last 3 pics from Day 22...am I seeing a calcium deficiency? She gets tap water, which I was hoping has sufficient calcium. But now I'm thinking I might need some Cal/Mag. Is she hungry for calcium?
