Water Schedule:



Currently watering about 4 Litres (approx 1 gallon) every 2 days



PH 6.4



Using a 3 Part fertilizer. Flora Micro, Grow and Bloom. Following the schedule from their site. I didn't start feeding them until 6 week into veg. Never showed any signs of deficiencies until then. Started off with 1/4 Strength and worked up to a full strength. Had to back off due to run off being over 2000 ppm. Using 1/2 Strength now.



A little back ground:



I have never grown cannabis before so this is all new to me. If my terminology or lack of knowledge is unclear, go easy on me!

I’ve been reading non stop since I was gifted a bunch of seeds. 5 of them are random strain that are unknown and 2 seeds are Jack Herer.

When I first started, I had them on a shelf under 6 x T8 5000k 32 watt Bulbs. Eventually upgraded to a 4’ x 4’ x 6.5’ tent along with an 8” fan and carbon filter. A week later upgraded to 2 x 600 watt led lights.



Flipped the lights at the end of week 8 (Dec 16th) to 12/12 and they are just about done their first week of flowering. I am pretty sure that 3 of the 7 plants are males.



I will post my progress pic’s up to the current date and keep updating weekly or as things drastically change. Any and all advice/criticism is welcome!!!!

Week 1 - 5 Unknown Seeds Sprouted!

 

[RuleAndrews]

Week 2 - Added some reflective material to the back...

 

[RuleAndrews]

Week 3 - More Growth

 

[RuleAndrews]

Week 4 - They seedlings out grew their pots. Put them in 10 Liter pots. 60% Soil 40% Perlite. Also added some gravel to the bottom of the pots so the soil didn't drain out. I also added two more T8's.

 

[RuleAndrews]

Week 5 - The two Jack Herer Seeds have sprouted and added to the garden. 7 Plants Total!

 

[RuleAndrews]

Week 6 - Upgraded to the tent and exhaust vent! Still running T8's. Also started with 1/4 strength ferts.

 

[RuleAndrews]

Week 7 - Upgraded to 2 x 600 watt led lighting. 1/2 Strength ferts.

 

[RuleAndrews]

Week 8 - Jack Herer's have been moved into 10 Liter pots as well. First half of the week 1/2 Strength Ferts, second half of week full strength.

 

[RuleAndrews]

Week 9 Current Week - Lights have been flipped to 12/12. Had to back off to 1/2 strength ferts. Run off was over 2000 ppm. Got it down to 1200 after flushing with 1/2 strength.

 

[RuleAndrews]

3 of the 7 look like males...

Thoughts?

Welcome Andrew, yep but 3 out of 7 isn't bad.

Welcome to 420 RA! Girls look good, getting ready to flip in a couple weeks my self.

Had to back off due to run off being over 2000 ppm. Using 1/2 Strength now.

I commend you in doing just about everything right so far... this is going to go very well for you and congratulations since it is your first time!

I did see a problem in what you posted though and I don't want you to hurt your plants that you have done so well with so far.
Please check your assumption quoted above... based on this you could now be starving your plants just at the point in the grow when they need more nutrition than ever.
There are a lot of people out there talking about runoff. I understand how easy it is to be taken in by all the BS being put out there on multiple forums day after day about this. Runoff is just that, runoff. Your water percolates through the now well used soil, and drags along with it any debris, broken down organics, salts and left over nutrients, into the runoff. It's pH and its ppm are mostly useless information.
Of course it has a high ppm. Of course it has a different pH as the water you apply. As the soil continues to break down the organics, these numbers will change even more.
This number now has very little to do with usage or not of the nutes... when the soil was new, maybe.

I've advised growers not to check runoff numbers because it just causes you to start chasing ghosts that are not there. If your ph and ppm are in range going in then you're golden.

 

[Emilya Green]

Its like analyzing your bath water to tell if you got clean...

 

[Pennywise]

I haven't checked runoff in coco for 2 years now.

Thank you for the reply! This makes so much sense...I was questioning this my self, but there is so much info saying different things.

Shortly after I started backing off with the nutes, I started seeing some changes with some of the plants.
I'll attach some pic's.

 

[RuleAndrews]

Thanks for the replies and sharing some knowledge!!!

These plants are magnesium hogs, and those are signs of the deficiency starting up. Get some calmag+, soon. A foliar spray every couple of days of epsom salt can help while waiting for the supplement to work.
