DWC Brown spots - PH EC fine maybe Lockout?

Overall concentration may be where you want it, but obviously there is an issue with nutritional balance if you have symptoms. So, it's not really 'fine' if you see symptoms Looks low on Ca or possibly high on P which could lock it out. Hihg p would also have light green new growth and maybe some more damage around margins (serated tips), so there should be visible signs to eliminate one or the other. in flower i'd shoot for PPM calculated from guaranteed analysis not a conversion from some cheap TDS probe. There is a big difference. One is gauranteed to be accurate and one is merely correlated. For flower phase N 80-100 P 40-60 K 180+ Ca 100+ Mg 75ish S 100+ This would be lwo end of feeding concentration.. if you fed well in vege, you often don't need as high of concentration going forward. For vege, i'd up the N to 120-130 ppm and everything else mostly stays the same. Your tap water may require a few adjustments, but otherwise the ratios of nutrients is good and overall concentration will depend on numerous local variables. This isn't 'my' formula. It's one that is used by several professional Ag fertilizer makers. it's a far superior formula to most marijuana brands. very few adjustments will be needed, and if they are they will be slow moving, easily identifiable symptoms with easy diagnosis and then never see again in future as you dial in formula. growbuddy? hydrobuddy? one of these free apps can take gauranteed analysis labels and tell you dose for target ppms. it's a very useful function.

Hallo, die Nähstoffe brauchen ein wenig bis sie ankommen. Sieht mir nach "Extrudat-Vergiftung" aus. Wasserwechsel war gut!
