So some of my plants had an iron deficiency, so as a precaution I gave my plants a light watering with CalMag (2 tsp / gallon) when they were due for watering.
That was yesterday. This was an in between watering, I feed every 3 days (they are under 2 600 watt hps lights air cooled, climate is 75 day 70 night, humidity hovers at 50%).
I'm using Botanicare Pro Gro, Pro Bloom, CalMag, along with General Organic Diamond Black and BioBud. They are 3 days into flowering (12/12) after vegging for 1.5 months and they are on week 1 of flowering. I was away and had a caretaker taking care of them, so rather than have him water them again when they were due I just fed them cause it had been 2 days, and they were ready to be switched.
Apparently this was a mistake? Can anyone help? The leaves are turning yellow, starting at the top, and beginning at the stem of the plant out to the tips. The veins remain green. Very obviously iron deficiency in my opinion.
Some of the plants have some yellowing leaves at the bottom with a couple brown spots on them, look like they are dying. But the majority of the plants look beautiful.
Also worth noting, I just did a double dose of 1:10 skim milk spraying before the lights go off, once nightly for the last 2 days. This was for a little PM issue, which I regret to even have to mention cause my grow room is fairely dialed in.
Any help on correcting the Iron deficiency occurring on day 3 of flowering after switching feeds? Thanks
