hey guys. i just fed these plants 3 days ago. they looked fine before i watered. I'm at 23 days w them. 2 ww autos 2 n.l autos and 1 n.l blue auto. fed 1/8 strength g.h flora nutes with 1tsp cal/mag per their feeding doses but at 1/8 strength. got them in 70% coir 30%perlite in 5gal. air pots. up till their last watering i was only watering a circle around each plant every 2 days when they dried. last watering/ feeding i soaked them with 10-15% runoff. 24/0 lights w/ king plus1200w and viparspectra 600w leds 20in. away. temps at 78 rh 40%. i just added a 1/8th tsp kelp and 1/8 tsp powdered gypsum into the top in. of soil yesterday. gonna water today w/ just phed water w cal/ mag. any ideas what the issues are. everything I've read seems to point at boron deficiency but last watering i did get some water on the leaves. could this be water burn? new growth seems to be coming in light green also. and some light yellow patches on some of the lowers leaves. any help is appreciated!

sorry posted the same pic 4 times but they all look the same anyway. 1st time doing pics. sorry for quality. my phone bites! also i find the growth isn't where it should be compared to other grows on here. very bushy.

I can't tell much... not that I'm an expert or anything the Dr's are gonna want pictures in normal light though

 

[steve bossie]

yeah. thought of that after posting. ill take some more and post them.

heres some white light pics. also use well water phd to 5.5-6. was using distilled then went to well water for this last water/ feeding. almost think i need more nitrogen but id figure to check with you guys 1st. they were much more green before this last watering.

Bugs?

 

[Potus]

Is that not holes in that one leaf?

 

[steve bossie]

no bugs and thats some dirt that splashed on that leaf. no holes. pics from my phone suck but I'm getting discoloring along the veins of the leaves. color has lightened since last watering. new growth is coming in light and growth has slowed. maybe need more n? any other plant , id think it needed more but i figured id post on here to make sure.

-- what size tent Steve? That's a lot of saturation going on in there,...might be a bit too close as well ; I do see some edge curl, and the light color, further hints at light intensity issues (LED can be tricky for this, the symptoms aren't quite ther same as with HID); feeds seem light and pot size for coco is too big.. this is one of the big advantages coco has over other soilless mediums, you can get monsters from smaller shoes because of coco's unique properties. Our best coco-nuts here go 1-3 gal max,... problem with the oversize pots, the dry-out time is long, and nutes get sucked up fats in the root zone, so feeds aren't getting in at the usual mild but constant levels,... Also, the actual in-pot pH should be taken too, just to be sure it's not too far off and causing some kind of nute lockout,... easiest and best toool for this is a quality pH probe.. the Accurate 8 is a decent model for the $! Otherwise, it's the PITA and, when done wrong, crude estimation technique of using the run-off method... here's a link to an improved method- https://www.autoflower.org/threads/...-for-run-off-testing-and-ph-estimation.41733/

i did move the lights last week about 4in. closer they're at 20in. now. ill try moving them back up. they're in a 4'by5' by 7' tent. up till this watering i was just doing a circle of water around each plant when they felt dry. should i go back to this until they fill out the pot? pot size is actually 4gal,. don't know why they advertise 5. they are incredibly bushy and dense. is that caused by the lights being close? i just ordered a in soil ph tester from amazon. don't know what brand. i have barely fed these girls also. only thing i gave full strength was cal/ mag because of what i read about growing in coir. thanks for the info. ill make some changes and let you know how it goes. happy growing sir!
