Your temps are too low. Plant looks waaaaaay over-nuted or/and over-watered.
having a meter in your medium is not how you ph. you have to adjust the feed/water. all the soil things do is measure the results of what you've been pouring on the plants. (actually, those things are a waste of money.) if you can't/don't adjust the ph of your feeds/watering, then it makes no difference what those meters read. if you don't eliminate ph as a problem, then there's no way, in most cases, to tell what's really wrong.
well I think I'm going to flush her good and just quit with the nutes for the rest of her flowering.... it's the beginning of week 8 of flower starting wednesday... this plant, since it's a reveg, plus the stress from all the shit I've put it through, I'm letting it go at least 12 weeks, maybe longer if it still doesn't look done... I have another plant in the room that's in much better shape, however it's much smaller (1gal pot), and not re-vegged. I think it's a different strain too. they are both bagseed from some good mids I had. this is only my second grow, so I didn't want to waste money on good seeds until I had a few grows under my belt. so next run I'm thinking one white widow x big bud and one skunk #1.
i like using a meter/ph pen, there are a few different ways to go, and price ranges. you also need something to adjust the ph up/down. i use pro-tekt, for up. once you have the ph under control, you'll have a much better idea of what issues you need to address...
Half a gallon in one shot is way too much water for that size plant. Your drenching it. Try 3 cups of water twice a day. Its like asking you to drink a gallon of water in 5 minutes to keep you hydrated for the next 3 days...not healthy to you...why would it be healthy for the plant. Plants in nature get small drabs from morning and evening dew and what little they find with the tap root. Not a torrent every 3 days and drought.
Take a look at his leaves. See the cupping and curling under? The plant is trying to stop transpiration because it's having problems taking up water through the root zone. That is usually an indicator of salt build up in the media.
That's crazy. With a healthy root system and good planting medium my plants in 3 gallon pots can drink almost a complete gallon of water or nutrient solution with minimal runoff. a 1/2 gallon isn't to much by any means.
are you using the meter you stick down in the soil to take these measurements? or are you doing it by pHing the feed/water and then testing runoff?
