Hehe.. well I admit I'm a newbie. The plants are small for their age and I'm not positive that isn't because of the ph problem as well. Most of them are about 5" tall.. :wtf: Pics this time...

A brief background is I germinated the seeds, placed the seedlings in the miracle grow gardening soil, and started watering them 1-2 times a week - didn't check water ph. At the time I didn't realize how important ph is.. about 2 weeks in I thought I would feed them (not realizing that the soil already has some food in it) so I mix some Sensi A and Sensi B (food solution) and give them each a watering.

Shortly thereafter I started to notice the leaves on the bottom turning yellow. Now up to this point I had been watering with tap water and feeding with food mixed in tap. (My tap tested to have a ph of 8..ouch) So I started trying to figure it out, but kept thinking it was an N def problem..which didn't make any sense because I had been feeding it N. So like an idiot I gave the plants a little more N. Then I thought it might be a ph nutrient lockout...something I had read about.

So I start testing my soil and realize its ph is super high, about this point some of the plants start to show what I think is chemical burn (crisp dead spots on tip/edges of some leaves).. so I start trying to get the soil down with a ph down solution designed for hydoponics. I make a big batch of about ph 5 (didnt know about the shock thing yet) water and rinse it through, lowering the ph a little...and then a couple days later I rinsed with ph 6.4 water again. The water that was coming out was still a little high (6.8ish water, 7.2ish soil?), so I'm probably going to flush again.

And then I started seeing these yellow spots between the veins...ideas? If you've read all that and have any input.. Thanks :weedpoke:
