I think my babies are sick

[Canigrow ceo]

So recently I’ve been noticing yellow spots on my plants , some of the edges are turning yellow and curling downward and upward... I’ve done some LST to them and topped them as well now they are about 17 inches tall and starting to become more bushier after defoliating the plants.... I’ve started noticing yellow spots on the leaves and they were curling some upward some inward some downward.... I’m using MG organic potting soil.... and now I think I’m giving my babies nute burns or maybe have a lock out idk I’ve flushed them all for the are in second month of veg’n. And even my newer seedlings are starting to reach and produce these crazy yellow is spots on my leaves... please help!!!! After flushing my ph is still alkaline do I need to feed? Or use PH up or something? I want my babies to be healthy cuz I want to clone them... as far as strain I couldn’t tell exactly what they are cuz I’ve been collecting seeds that I’ve gotten from the stuff that I would smoke and decided to keep the seeds. Now I decide to do my first organic grow and I need help....!!!!!!! Plz how do I cure or are they sick?? Is it leaf septoria ???? I can provide more pictures even a video if need be....

First, with organic grows, pH is generally not an issue. Plants get their nutrients from the soil, not chelated chemicals put into the soil. Which takes us to the question...what are you feeding them, how much and how often? And because organic grows get their nutrients from the soil, you really cannot flush them. You are basically just really overwatering them when you try to flush an organic grow. However, if everything about your grow is not organic, it is not organic. The use of any chemical fertilizers can kill any good microbes you have going in your soil.

Now a word about bagseed. Virtually all the seeds you find in a bag of quality weed are going to be a result of the plant selfing. This creates seeds that are far more likely to hermy, genetically predisposed to hermying. Any little stress can cause them to develop pollens sacs and pollinate your entire crop. Sometimes these nanners are hidden and you don't even see them--you just end up with a crop totally seeded with worthless seeds. And keep in mind that even if it did get pollinated in the old fashioned way that you only know 1/2 of the genetics. Those plants could have been pollinated with ditch weed with 0% THC. It is going to take 4+ months to finish a crop. It sucks to get to the end of that and have a fully seeded inferior harvest. It certainly is worth it to pay $50 or so for known quality genetics.

I try to stay away from anything MG. Part of it is that they (and Scott's) are in bed with Monsanto, a company that is poisoning the earth and killing people just so they can get richer. The other is that cannabis just doesn't seem to do well with their products (but mostly the first thing).

You "defoliaged" your plants!?! Why!?!

Tell us about your lighting. I think they need a lot more light. Also, do you have any ventilation for your space? Do your containers have drainage holes?

Well I would disagree with a couple things you wrote THG. Yes salt based nutes are chelated for the plants to uptake immediately, but microbes , mycorrhizal fungi in particular convert the organic nute into a chelated form so the plants can uptake them. Organic soil grows are not necessarily ph balanced. When there is microbial activity the ph can and does fluctuate. It is when an organic soil is balanced that the ph is stable. Flushing an organic soil can be useful when the soil is unbalanced. It is like a reset button and the microbes will start recolonizing very quickly with the right environmental conditions.

Water pharming with a live res. -- Organic or not ? -- PH fluctuates ?---- Yes!--- Different nutes Absorb at different PH--

After you flush them, do you feed them right away?
They look hungry.
They need light. Lots more light.
They look overwatered. Mycos in the soil still need oxygen to work their magic, don't drown them.
A plant will happily suck itself dry on a 1-3 day cycle in a correctly sized pot. If you aren't getting fairly dry between watering, your roots and the beneficials helping them are drowning.

More light. Ample supply of pH balanced fertilizer solution (organic or not, when in doubt, balance your ph) given sparingly since your pots are too big for your plants and therefore they are sitting in wet stagnant soil. If your room is cold, even worse.

This looks like cold/wet/hungry/need more light to me.

Also never trim leaves unless you have to as part of a last ditch effort to remove a diseased or bug infested part of the plant. They will drop when the plant wants to drop them.

Also I think you may have thrips. Leaf damage is a clue. Check for tiny gnat looking things flying around, and tinier golden' splinters 'on the upper leaf surfaces. Which would make sense in a cool damp soil environment.

After having to deal with Leaf Spot (Sephora) last Summer it does not look like these plants have it.

Good drainage is important. If your soil stays wet it will cause problems which can make the leaves on your plants look like they have other issues.
