Hi @Simsalabim! Sunlight activates photosynthesis and the more sun the plant gets the more nutients it will require. Basically, your plant is consuming loads of nutrients due to sunlight and pre-flowering stretch. She needs more Nitrogen and probably some other elements such as Magnesium, Zinc, Copper... You can increase BioGrow up to 2.5ml/L and add a teaspoon of epsom salts in your solution, this should help her for the next week, but be warned she will soon ask for P and K while entering the flowering stage. Nutrient uptake is probably slow because of the lack of container so you can also consider foliar feeding, this should prevent the deficiencies to spread, but avoid spraying anything once the preflowers are out. Hope this will help, keep us up-to-date and happy growing ๐

When I Google deficiencies / toxicity I can compare some phosphorous deficiencies to your leaves and find out that the symptoms are the same so I would say phosphorus (P) deficiency with the rust part on your leaves , what you called brown blotches. The 2nd deficiency you have is a potassium one (k) as you can see some of your leaves have the edges that are starting to turn brown which is the 1st step then rust spot appears and a discoloration happens. 3rd observation : if the soil is still moist but the leaves are really droopy then it is an over watering issue , the symptoms of an under watering are the same but with a dry soil. 4th on the Bs#18 I can see the lower leaves yellowing which mean you have a nitrogen deficiency. To finish my answer I give you a link to a deficiency / excess chart ( in the comment section) that will allow you to find your issue or at least compare the external diagnosis you get from the Community ๐โ๏ธ๐ผ

Leaf tips turning yellow or brownIs it normal for leaf tips to start turning a different color? I thought maybe it was nutrient burn so I flushed it a few days ago.
Iโm a total noob with growing so Iโm not sure if theyโre supposed to get better after a flush.

Calcium excess, which led to potassium deficiency? Or just light burn? Or both? What's wrong with my girl? Please, help.I've been giving her BioBizz in accordance with the schedule, including CalMag. Using tap water (250-300 ppm). So my only guess is calcium excess, which led to potassium deficiency.
However, only the main cola is affected now. So I also suspect light burn.
What's your opinion?

LightingI have a question, on one of my sprouts it appears to have slight discoloration in the tips it looks almost white. It has been like that sense the seed shell came off. The others coming up look just fine but wanted to make sure it was not getting burned by the lights?
