Not TMV likely temp induced Ph deficency
MarijuanaMiyagistarted grow question 3 years ago
I just checked my min max gauge and it dipped below 15 in the shed lastnight and I think it may be phosphorus deficency due to temperature drop. I haven't seen it manifest like that but it sure seems like it. Bring it in at night now seeing as temps plummted.

Yeah, low temps will quickly turn your plant different colors -- dark purple / red etc. Will look like fall... for same reasons.
it is related to how it impacts nutrients, but you want to fix the environment as opposed to changing nute mix. 18C is borderline... some strains may still turn at this temp too. Once it starts going, it doesn't take many nights to speed up.
good idea bringing it in... will be a hassle of course... late in flower can just live with it if you want. Usually get soem pretty pictures t the least, lol.
The advertised bloom periods are almost always a fib. plus, about a week give or take just based on personal preferences. (about comment from diary) Definitely experiment with different points of harvest window. use trichome coloration as guide. Get a 30-60x jewler's loupe or currency checker etc... build up familiarity.

Too late for another trimming ?Show I do another trimming ? Most of the big upper leaves started having trychromes at their base so I am not sure if I should trim again at this stage.
Currently in the 7/8th week. I already trimmed twice during vegetation and beggining of flowering.

Bad appearancethe leaves seem a little clear, strange, I don't know if because they are new, but before they look darker, the amount of nutrients seemed good to me before, but I increased the N to see if that corrects it, I would like more accurate views. I have another genetic using the same

The leaves are large and big but sooo thin! Burntips and little holes.Does anyone know what could it be?
Got a tipburn in one leaf and 2 others with extremely little holes, but didn't see any bugs or look-a-likes in my grow.
Is it normal to the leaves be so thin? It's my first indoor don't know if indoor plants used to be like this.

Spots on leaves after spraying with Plagron Vita RaceOn the 4th of March during lights ON I sprayed my plants with distilled water with Vita Race (3ml/L). I noticed that after it dried up there are some weird spots on the leaves that were left behind (see picture). Any idea if that can lead to problems later?😅

Potassium deficiency?Needing some help. I have this going on in my flower tent. They are in week 6 of flower. Of the 4, I have only one showing this bad. She seems to be locked out on me as well. Could this be a potassium deficiency? Seems to only effect upper fan leaves.
