Indoor autoflowers in coco with dr earth

[redxber]

greetings fellow growers

old dog, new medical grower had a couple semi successful photo period grows but recently found auto flowers and coco first auto run was my most successful yet though made several mistakes, some unknowingly until I found home here and started reading
current grow in early flower and wanted to share my grow.
2-9
6 seedlings
5 white lsd
1 granddaddy purp
msnl seed bank
coco buffered with cal/mag w/ worm castings and dr earth all purpose, veg, and flower girl dry amendments following youtube growers Mr Canuck and Stealth Grows and using 3 gallon fabric pots
first auto grow was done with ratios similar to Mr Canuck used with the two part dry feet mixed into the coco only using the all purpose and flower girl this second grow added the veg dry feet following Stealth Grows 3 part usage
mixed into the coco/worm castings and perlite for each 3 gallon was
3 tlbs all purpose
5 tlbs veg
4 tlbs flower girl
my first top dressing @ 4 weeks from seedling used
4 tlbs all purpose
4 tlbs veg
4 tlbs flower girl
last top dressing which will be early flowering 3 weeks later will be
5 veg
7 flower girl

all watering has been done with tap water run through 2 boogie brew filters to filter out chlorine, chloramine and other stuff. I am using the boogie blue basic as a pre filter and then through the boogie brew classic.
the filtered water is ph’ed to around 6.5 with 1 tsp cal/mag

3-2
time for top dressing
4 tlbs of veg
4 tlbs of all purpose
4 tlbs of flower girl
also doing a little LST

 

[redxber]

Nice recovery from the LST
keeping humidity around 75% with a humidifier and humidistat controller

3-8
another round of LST
Strange bleached spot on 1 leaf. As of current no other issue like that on any of the 6 plants.

3-14
roots are growing out of the 3 gallon fabric pots

 

[redxber]

Some more LST
I never topped these autos and only defoliation that has been done has been a few fan leaves near the soil level to aid in watering and the newer suckers that are trying to branch off

3-19
7th inning stretch into flowering
going to back down the amount I am using the cal/mag to ph my water and go back to mostly using the ph down
will do last top dressing this weekend with
5 tlb veg and 7 tlb flower girl
will also defoliate any fan leaves covering my flowering sites and considering putting my other hps fixture up in my 2nd 4x4 that currently has seedlings under mars hydro SP250’s and spreading out the plants to 3 plants in each they are cramped with all 6 in one 4x4
Thinking of adding some of the organic general organic bloom booster to the watering as a boost
removed the humidifier because having no problem holding at 50% humidity in fact have had to turn the fan/filter up a bit because I am watering 2 times a day and it was keeping the humidity around 60-62%

today I did a final bit of LST and my only major defoliation. Up till now I have probably taken around a hand full of leaves and sucker branching total off of the 6 plants. This round took any new branching, immature branching and large fan leaves that are covering the flowering sites. I also split up the plants and now have 3 in each tent under 600w each with the ballast setting turned up to “super lumen” setting.
in the plant pics you can see a 4 foot led tube used for size reference. All but one of the plants are running about 3 foot tall in 3 gallon fabric pots that are around 12 inches tall. The 6the plant seems to be a pattern with the MSNL white LSD auto seeds and was a runt the third up to about 2.5 feet in the flowering stretch. If there is any stretch left they will even out the canopy due to the LST they went through.
top dressing was done with 5 tlbs of dr earth vegetable and 7 tlbs of flower girl per plant.

I have identified a nutrient deficiency in my plants. A brother and I were talking and I was seeing some fading lower leaves earlier in flower then last time. We talked over the possibility of an N or K deficiency.

happen to see a video by youtube personality Lex Blazer in my feed on potassium deficiencies an one also on N deficiencies. I posted the potassium link below
N deficiencies usually happen in the vegetative stage and cause purple/red color on the stems. I am in the 2-3 week of flower and no purple/red.

the lower leaves are Fading to yellow
seems to be mobile
its in early flower
tips of upper leaves seem to be experiencing leaf tip burn
issue is from adding too much cal/mag during veg stage and it has created too salty of soil causing the plant to heat up and burn and locking out the potassium in the medium.
Flushing and compost tea was recommended
i did not flush with the organic dry amendments and top dressing as I would flush out my nutrients so next several waterings was done with plain PH’ed water
I had a sample of boogie brews tea that came with my water filters so I brewed 1 cup into 5 gallons of water for 24 hours and used this, ph’ed correctly, to water with tonight and will apply a Foliar spray in the morning
