Started 1st grow ever in August. Using Fox Farm Ocean Forest/perlite mix. Through 3 weeks plus, everything was perfection and grace.
Foolishly added nutes at 3 weeks (Botanicare Pro grow 3-2-4) in a very weakened state (33%strength)
Got some minor tip burn and flushed at 4 weeks (in 6" azalea pots, have to flush at some point anyway)
2 days after flush, 7" - 8"+ plants had dry pots, so nuted again at 50% strength using same stuff (Botanicare Pro Grow 3-2-4)
NOW...things begin to get complicated...A day after nutes, 3 days after flush...
I get rust spots, some yellowing of leaves, some brown spots, necrotic spots,
and basically all kinds of defects that all can be matched up with numerous nutrient deficiencies in pictures here and on several other websites...
I had a pH problem...and only a lousy cheap soil meter that lied...
Within a few days, I had liquid pH tester and a professional grade soil pH tester shipped in...(with 5 plants at 4 weeks+, I had to try something!)
pH's were off in all 5 pots...multiple tests revealed a pH average of 5.5 to 6.1 in all the pots. My tap water runs 8.5ish. My brand of spring water runs 7.5ish. Distilled water out of the bottle fresh is 6.7ish. when I mix nute solution into ANY water, it drops the solution DOWN in pH. I have also used sparingly a CalMagMolasses additive (free sample) and Botanicare Liquid Karma (free sample)...both of them also drop pH...
I have since stabilized pH's and have kept them between 6.2 and 6.9 in the pots. I also potted up to 2 gallon pots in an effort to keep the pH more stable for a longer period of time...(maybe a rookie mistake?)...
So where I stand right now is...
I have 5 plants, over 5 weeks old...stable pH (for the moment)...
They are 10" tall and growing...they still aren't perfect, still have some damaged leaves from the previous problem (I pruned many of the really bad ones off)...
I also used baking soda twice as a pH stabilizer and now wonder about that...
Although 85% of the plant looks perfect, all I can focus on are the bad spots.
Thinking I should flush again with stable pH water (distilled 6.7ish)...
then let them dry and see what happens...
What can I expect from here if I keep pH balanced? How do I avoid further nute lockout problems. Once they have a few bad spots, will I pay a price later? In a way...I'd like to get them into 12/12 cycle and get this 1st grow under my belt and move on...but do I need more stability first?
Thanks, P.
