So I'm trying to discern whether I have continued to over water or if I am suffering from nutrient lockout due to ph.
I have test strips, but here's the thing: Instructions say to dunk for 2 seconds. When I do that the ph reads at or above 7 but lower than 7.5 ... however if I allow the strip to soak in the water for a minute or two and swish it around a bit the reading is closer to 8 which would cause problems, yes?
Plant symptoms:
After repotting they take off, even after 2-3 waterings they are looking good, but oddly, the plants repotted first are stunting again, showing a tinge of yellow, and some purpling of the veins. Also 2 cumaris are showing yellowing with some brown spotting on the older leaves. It's these cumaris that make me think it may be lockout due to ph because they show the brown spots which indicate a deficiancy from my readings here: http://www.hydroponics.net/learn/deficiency_by_element.asp and looking at the cannabis leaf photo kicking around that shows examples of all the different issues..
Frustrating!
Watering regiment: is now ONLY if leaves are drooping and even then I only put a small amount of water into the bottom of the cup for them to soak up. Oscillating fan is on the plants as long as the lights are on and is quite strong.
Question: If a ph issue, what is the best way to lower it? I've read sulfur but I have no clue where to buy that and would think there must be an easier home remedy.
PH strips at 2seconds 20seconds and 90seconds soak:
Veins:
Brown spotting over/under:
Thanks again to everyone for helping me sort out my first grow from seed.
