OK so here is the rundown

Average Soil PH: 6.5-6.7
Average temps/ Humidity Morning 70F 63%
Afternoon 85-95F 52%
Evening 63F 65%
Medium: 50/50 mix of FF ocean Forest and Happy Frog with added pearlite
Light Schedule: Outdoors/San Diego, CA
Nutes/Food - 1/4 strength Thrive Alive B1 Green 1time per week foiler feed.
Water: Reverse Osmosis Drinking Water twice a week
Pesticides used: Ortho EcoSense Insecticidal Soap once a week

Ok so thats the main info now for the problem. I have 4 plants outdoors 24/7. Begining of this week started noticing Rusty Brown Spots on Edges of Leaves on lower branches and the upper branches are clawing. The plants are in 5 gal grow bags. The plants are all on their 5th week from seed. All four are bagseed so pheno;s unknown but, One seems to be doing just fine so, I am pretty sure it is not enviro. I was thinking a K def. What do you guys think.

do you have a good mag glass (one you may use to inspect trichs?) take a look at those leaves with it and find out if you can confirm any insect infestation. iam not positive but that looks a lot more like chewing than a deficiency.

The first 3 look like spider mites. The third appears to be a deficiency of some sort (I dont know them all of the top of my head but i think it is P). Is the problem on the lower leaves or upper leaves? If it starts on the lower leaves then it is a mobile nutrient. IF on the tope leaves then immobile nutrient.

It started on the bottom and moved to the top. There are two spiders on my plants and both are common garden spiders, they have small webs and eat everything. Those white speckles are old from before I started the insectiside and have not grown at all. I hope this tea brings em back it was a pain to get eveything set up for it.

the brown spots are not getting any worse now after a soil drench of my compost tea but, The curling is getting worse any ideas, they were watered on Sunday and will water again when they dry. Is it to much water or too much heat?

"Potassium deficiency (K).
Older leaves are initially chlorotic but soon develop dark necrotic lesions (dead tissue). First apparent on the tips and margins of the leaves. Stem and branches may become weak and easily broken, the plant may also stretch. The plant will become susceptible to disease and toxicity. In addition to appearing to look like iron deficiency, the tips of the leaves curl and the edges burn and die.
Potassium - Too much sodium (Na) displaces K, causing a K deficiency. Sources of high salinity are: baking soda (sodium bicarbonate "pH-up"), too much manure, and the use of water-softening filters (which should not be used). If the problem is Na, flush the soil. K can get locked up from too much Ca or ammonium nitrogen, and possibly cold weather."

you have leaf spot fungus my friend very hard to get rid of and there is nute burn you dont need to be adding nutes at this stage just plain tap water not osmosis water just tap water thats left stood for 24 hours it has nutriants in it even direct tap water is ok there is no evidance to suggest that chlorine has any effect on cannabis plants

are you spraying them after the sun goes down with plain water this will help any bug problems

stop giving them nutes and the osmosis water keep it simple and you will see mother nature does not rain osmosis water there is enough nutes in the soil to keep them in veg for months

good luck m8

You need to add calmag or something organic that is similar. They look hungry and very stretchy. The damage from the mag/cal deficiency will not heal but they should live. I use ro water too and add the full recommended dose of magical to every watering. The ro system removes bad stuff but it removes some of the good too. Good luck.

thanks guys I was originally thinking K problems but the problem still persists after my organic tea which contains fish emulsion. Im pretty sure its not a fungus, the temps are to high and the humidity to low. I am going to allow to dry then, water with my tea again. This time the tea will have brewed for a few days so It shoud work better. I also use the tea as a foiler drench as it wards off disease(a lot of good it doing me so far though)

This is a true statement. Commercial greenhouses put as much as 8-20 ppm chlorine into there recirculating hydroponics systems. This said, you are growing organic. While chlorine may not have any effect on the plants themselves, the bacteria colony that breaks down your organic fertilizers will be greatly depleted after only putting in trace amounts of chlorine.

I don't know what is happening to your plants.
