Spots on leaves
HappySkunkstarted grow question 6y ago
Could this be the beginning of a Phosphorus deficiency? Or something else? It’s not really found on my oldest branches, but more my newer ones.

I would say that's a slight calcium defeciency, just add some cal mag to the feed.

LSTGood day!
I have a question for experienced growers who've used LST.
The stem usually branches out to 2 branches, one of which is just one big leaf and the other branch has nodes & other branches.
Do you put the branch with the big leaf below the rest, above or prune it?
Thx!Leaves. Other

How dark is too dark?Are these looking too green? I’m not seeing any N-tox clawing but they are pretty dark, growth is pretty vigorous and steady though so I don’t know. They are in a pretty rich organic medium.Leaves. Other

Can anyone help sort out the issue I'm seeing on the lower leaves? I think I'm either between nutrient burn or potassium deficiency? I did up the nutrients a bit this week when I saw yellowing, but also have had high runoff pH the whole grow. Though haven't seen any other issues.Week 13

Manchas en las hojasHola amigos! Estoy teniendo algunos problemas en las hojas y aunque creo que con Calmag se solucionarán me gustaría oir vuestras opiniones. He notado también que algunas puntas de las hojas se curvan hacia abajo, ¿cuánto creen que me está afectando la temperatura de entre 27-30º?Week 6

Root rot? How to fix mid flowerWhat is this and how do I fix it! I am mid flower, plant is not drinking as much as usual, there are several "bleached" spots that I haven't been able to account for-- my guess is root rot despite plant otherwise seeming ok.
How do I fix this midflower with home items?Leaves. Other

Suspected Calcium Def?Think this might be the start of a calcium deficiency. Only on two of the older leaves and in similar spots on the leaves. These leaves may have also had some water on them after the last watering. Tried to remove it as best I could. Any thoughts?Week 4
