Soil Supreme is a unique blend of sphagnum peat,"Peat Moss- is an organic product derived from the slow decomposition of sphagnum moss which accumulates in bogs. The moss decomposes slowly under water. It is harvested by draining the peat bogs and collecting the material by various means. It is the most common ingredient found in North American potting mix formulations. Peat moss has no nutrient value and is acidic."


ya you should feed, can i ask how old your plants are

when did you transplant last

what nutrients are you using currently

i only used magne cal last 2 waterings because i thought this was a cal/mag def but now im thinking lockout due to the low ph run off? DSCF0295.jpgDSCF0297.jpgDSCF0302.jpg

Sounds like a "soilless" mix to me. Soilless mediums are really a pseudo hydro and you should be running your nutes at the ph range of ph 5.8-6.2 to make phosphorus available. This is more important in flower and you can run mid 6s in veg just fine but you really need to keep it in the 5.8-6.2 sweet spot for good production in bloom.

I would also consider going into a gallon, 3.8L pot as well.

I didn't read anything about there being organic compost in that soil.

"Soil Supreme is a unique blend of sphagnum peat, Fytocell foam and our very own OrganicGrowth Stimulant."


Whatever their organic growth stimulant is I can't imagine it being compost.

If your runnoff is that low than your fertilizers are PHing it anyways. Personally from the pics it looks like Calcium deficiency to me as well.

this is on the link
"Plant Magic soil would be classed as a ‘light-mix’ soil as it blended with a level of ORGANIC growth stimulant containing Humic and Fulvic acids to get your plants off to a flying start.The ORGANIC growth stimulant and well aerated structure facilitate a healthy root-zone environment for beneficial fungi and micro-organisms to thrive."

don't go worrying about the ph 'run off' mate. it's what goes in you want to know about.

looks to me like potassium and magnesium but i'd love someone else's opinion as i'm in the same soil

thats the forums for you lol. someone who has had the exact same problem is who you need to chime in.

i had some plagron worm humus left over from previous grows and i added around 5-10 % into one of my 4 pots just to see if there is any difference, the other 3 have just PM soil.

the soil is only for your plants to get off to a good start as you know mate, it's still up to you to provide the essential elements and micro's especially for when you're well into flowering.

what i ment was see if you get any signs of deficiency's, not flowering yet but they all have pre flowers so should be in flower soon, i think i have been under feeding them and this has caused the deficiency's and slow growth next feeding gona up the dose, lights of atm back on at 9 ill take some photos then if i remember, mine exploded when they were young aswell but they are auto's and recently they have slowed
