First grow advice

[Xeper13]

Hi, this is my first grow and I was wondering if everything was ok and if anyone had pointers for my grow, also one plant has developed what looks like a deficiency.
3 Autoflowers - sweet seeds Bruce banner/ free seed gelato/ free guerilla glue

Coco coir, following Dr coco. 3 gallon pots, water once to three times a day usually to runoff using general hydroponics with just calmag as a supplement. Tent is a 36" x 20" with 2 bloomspect 100 watt leds. Lst'd

The middle one kinda stopped flowering for a week after I defoliated because she was in the middle so I could have more space, she did however grow taller and grow all the greenery back. The right one has developed what looks like a deficiency, I'm guessing calmag but mainly on her main cola leaves. Any advice would be welcome.

Watering 1 to 3x/day to runoff? Are the pots really dry and lightweight in a day? The plants look good, have you looked at the leaf issues identifier on the main GWE site for the R plant? What's your pH? you might need to elevate that pot to keep your canopy even. You've got a full tent going on there. When were they born and how long have they been flowering?

Thanks for responding pug...ya I water at least once a day and check runoff ec as on this website..https://www.cocoforcannabis.com/. It's day 46, ph is 5.7 to 6.3 at a 1540 ec. Your idea of elevating the small one sounds great, I'm going to definitely try that!
