I dont know why Leg OG growing slowly? Today is day 14 for WW und Leg OG and 13 for Critical. White Widow growing so fast. I think she is easy to grow and perfect for SCROG or LST. WITH the next watering I will start to use Sensi Grow A + B.
3 different types seeds. LEG OG is too small and I will use LST, because I want all of them to be in one level and when they have the same level start with the Flowering.
Who can help me with the problem with the leafs? I give them the same EC 3.6,7 same PH5.9 - 6.0, but before a week i make watering with EC 4.3.Can be this watering a problem? By WW and Critical havent a problem.
little tacoing and rust spots...
EC of 3's and 4's? really? this is too high if true.. probably lockout. But, i'd expect to see a bunch of coinciding symptoms if this were true. I guess if it's every 3rd irrigation it's protentially okay? would need more info to rule that out (rhetorical) -- you have that info so if you feed that much more often, it is a possibility.
The rust spots on their own are likely Calcium related. BUT, if EC is really that high, lockout is possible.. high p or k coud cause this but you'd also see other issues on the plant concurrently.
Manganese toxicity is another possiblity of the rust spots. Check labels of what you provide.. if something is high in this, you don'tneed much... talking millimoles per liter.. 1/100th to 1/1000th of the primary nute concentration levels. ('millimole' is 10^-3 of a mole so "6.023*10^20" instead of 10^23 .. numbers so large it's hard to fathom)
the "taco" curling can be from heat or light in most cases.
