Hey there. Im growing outdoors in pots with peat/compost/perlite. One of my plants has been gaining brown markings that is even present as spots on the newest of growth. What can I do to get in front of it? I should add it feels like it started light and moved to darker. Can get better pics if needed. PH of water is between 6.5-6.8

no need for calmag outdoor... even with very soft water, except maybe during budding stage
calcium deficiency make rust spots on middle leaves .. mag decolorations between veins
post a photo of the whole plant, 1 leave or 2 means nothing

Gotcha. Only using biobizz (Biogrow) at 70% strength have worked up from 25%. Has been getting warm up to 80 or 83 degrees. I’ll look into calmag as I have PH test kits on the way.

do not worry bottom leafs eventually its gonna fall of


İts ok 83 F. maybe the ph range is not in place. maybe thats why she is feel deficiency. ph is very important. let us now what it is. if you mix nuts. you need to know order.

silicon
cal mag
micro
grow
bloom
bloom booster
humic asıt and teas
wetting agent
add ph down or up (do not adding directly to the solution, adulterate it with water)

No need for cal/mag outdoors? WTH? Depends on strain. I use cal/mag a lot. I also dust dolomite lime in my peat moss.

If you have no other source for cal/mag, salt based will save your plants. They do make organic cal/mag, it is much more expensive.

Plants look good there not lacking any thing. Don’t over do it. Keep an eye on ph and fluctuate it between the recommended range for your medium Different nutrients get taken up at different ph levels the lower the ph the more nitro your roots will send and usually there’s good mix of nitrogen in soils bit higher You’ll use a mix of all the Nutes (your mid range ph). Sun Outdoors also will make your plant use Nutes a lot faster then led spectrum lights. Also dries quicker.. so on so forth.
