Cool grow Steve! What made you go with Miracle Grow, over - say, Dyna Gro or Jacks? Same price point so I'm curious.

 

[steve870]

I got it on clearance at 2,30$ cad per 2kg bucket. It should last me years as i bought around 10 buckets lol

Everything is going alright, small signs of a calcium/ magnesium deficiency. I suspect my coco coir wasn't as buffered as it was advertised, will be applying a foliar treatment from now on until the situation is corrected. Those leaves are going to be huge though

 

[steve870]

grow rate is increasing, it is much faster and vigorous than my previous soil grow.

ok it seems like what i though to be a mag deficiency is actually a iron deficiency. Probably too high Phosphorus. I will be adding a tad bit of chelated iron to my water. Also planning to foliar spray it
i will be scroging too just installed the net

 

[steve870]

switched to a 400w MH light. Increased water consumption

 

[steve870]

Starting to fill the net

What made you go with iron deficiency over mag?
I'm a noob. The iron deficient plants look a lot different to me.

Problem: A cannabis iron deficiency causes bright yellow leaves on new growth. This deficiency is usually caused by problems with pH.

[steve870]

because i am giving already alot of calmag and foliar spraying too and it didn't correct the issue. Once i added chelated iron the deficiency was corrected

Starting to have difficulty controlling some plants, i will soon have to flower. Maybe in a week. It is going very well

Clean of them large fan leaves, let light and air get in there. I would top some more and place new tops in their own net holes when full then flip.

 

[steve870]

the net is already full on one side. The other side is getting there!

 

[steve870]

switched to 12/12 with a 600w hps bulb

 

[steve870]

 

[steve870]

cleared up some of those lower leaves, stretching phase

 

[steve870]

switched to water recirculation with bloom nutes, will be away for a week

 

[steve870]

[steve870]

leaving them for a week, defoliated some more

 

[steve870]
