Blattspitzen Braun langsameres Wachstum

Ich bin da eher bei Kong und dem Licht. Gegen den Kaliummangel sprechen die trockenen und aufgerollten Blattspitzen. Diese verbrannten Blattränder sind eigentlich typisch für viel zu viel Licht.

agree with kong.. and it doesn't look like internode length is super short, so less likely light-related and more likely K-related. start trackign either ppms calculated from guaranteed analysis labels or weighted average of the percents of each nutrient element relative to individual dose/total dose. added e.g 6 total mL added... 2mL from a 15--0-0 with no N elsewhere added would be 5% N not 15%. (15 x 2mL/6mL) .. and if other pructs used with N have to take the adjusted percent and add to the 5% here etc etc... weighted average relative to dose added. ml/L and brand-specific instructions are esoteric information. Not apples to apples for anyone reading it. PPMs or weighted average allos you to communicate with others in similar tearms -- apples to apples, regarldess of brands or products used. There is technically some room for variation even at similar PPMS, but small differences due to sources of the nutrients. This infor is also comparmentalized to each context of soil vs soilless(or hydro). soil needs different amounts due to how those nutrients need to be broken down by microbes.. need a lot more N in that context than soilless, for example, because it's not plant ready out of the bag. Anyway, focus on the ratios.. adjusting them based on observing the plant. this will shorten the learning curve and find a good formula that works on 95% of plants much faster. EC of overall concentraion is likely between 1.3-1.5EC. Environments vary, so total concentraion will vary much more than ratios of "good" formulas.
