Hi all, I'm not quite sure why my 1 plant particularly is showing hard signs of deficiencies. See picture.
What has changed over the last few weeks?
- plants went into flowering (today is day 44 from seed)
- amended the soil with Dr earth all purpose & flower girl on 2/14 and again on 3/8 (deficiencies were already apparent on 3/8)
- very slowly increased light wattage (turned back down to ~165 watts to keep humidity higher
- RH between 55%-65%
- fed twice with 3ml of General Hydroponics Cal-Mag in the last 3 weeks.
I read in a post on here that too much light coupled with too little humidity can make the plants transpire more, and in turn use less of the available nutrients. I turned down the light output and turned up the RH due to this info.
Another train of thought is that too much nitrogen can lock out phosphorus and other nutrients. I had a pretty decent nitrogen toxicity around week 3 from seed.
Please help me take these babies over the finish line, I've never been able to keep plants all green throughout flowering
