Hey all, first time grower here! Gonna try to take you on a quick summary of my grow so far so you know where I'm at and give an idea of what I'm thinking. Hopefully this helps.
Medium: 100% Fox Farm Happy Frog
pH: Tap water tested at 8, watered the pots and tested runoff and it was at 6.5, so I felt good about not doing anything else for a while. From my learning and research, my understanding was don't worry about pH with soil until there's a problem.
Lights: 20/4 schedule, 250w Migro Aray 4. These were an issue at the start because I was trying to go through my smart controller but that caused a flicker that I didn't notice or correct until about day 3-5 after sprout. a couple of the bunch looked to be stretching, eventually got lights in a decent place. We are now at day 20-22, lights are at 60% and sitting 14in from the top of the highest plant. I do not have a par meter or other light tester but I don't believe light to be an issue here, though it was at first.
Seeds: Mephisto Genetics - these are all autoflowers. There are four in the bunch, but the two with the problems are Gold Glue (yellowing leaves) and 3wok OG (brown spots on leaves). Planted on 4/30 and all sprouted within a week
Started grow using the method outlined here: https://www.growweedeasy.com/easiest...-seeds-in-soil
At first I did not have the pots elevated with much air flow to the bottom, and I know this caused some difficulty with overwatering. I lost one obviously stunted plant already, so now I'm very paranoid about overwatering, but I think the rest are in decent shape. At this point, I am roughly following the watering schedule described here, though also watering slightly less because I am using 3gal pots instead of 5gal: https://www.growweedeasy.com/how-to-...g-in-a-big-pot
Last watering was on 5/21 (day 17/18), 3 cups of water to everyone, with nutes.
This is where I think I messed up:
Nutes: I gave 1/4 strength FF Grow Big at day 12 (5/15) to 3wok OG and Gold Glue, since these were starting to enter vegetative state (I read a lot about "when does vegetative stage start" and landed on "when 5 and 7 pronged leaves start showing up." I'm starting to think my confidence in all this was misplaced and I went way too early. So, watering every 3 or 4 days, these plants got watered on 5/15 (~1.5 cups), 5/18 (~2 cups), and 5/21 (3 cups) with 1/4 strength Grow Big.
ALSO, in the days following starting to give them nutes, I realized my humidity was probably too high (kept around 75-80 RH since the grow start since I read 75-80 was good for seedlings, but should be dropped as time goes on.) So, on 5/20, I got a dehumidifier and the humidity dropped to 55-60 RH within the day and has stayed around there since. Not sure if this is pertinent info, but a big shift in environment just days before these issues started showing up seems like a potential cause.
My plan of attack:
First of all, I'm asking everywhere I can think of for help. I have ordered FF Cultivation Nation pH Down (I didn't know if I could get just any pH Down, so I thought it safe to buy FF, was this unnecessary?). From my internet research, I'm thinking that if I drop the pH of my tap water to an acceptable 6.5, and then water the plants, this should help flush and reset and clear things up. From my limited knowledge, I know that a lot of things can be fixed with Cal Mag, which I have also ordered and will have on standby. Would it be a good idea to add Cal Mag in when I attempt to flush, or just flush with pH'd water?
OR OR, am I going about this all wrong? Is there some better way to fix this or diagnose this?
Any help would be appreciated. And if there is any additional information I can give, please let me know.
Thanks in advance everyone <3
