Ye ive done a fair bit but loads to learn(Northwood ,Richardrysift learnt alot from their threads and many others),the other guys are rite tho there are a few bugs in there but i havent found any on the plants, jst in the soil. The straw has kinda moulded into the top soil, its actually hard to remove it,I was checking for those bugs and had to rip the straw from the soil just a small section to have a look.
 
If you have been trying to grow organic, and increasing your good bacteria. wouldn't you have just been killing it anyway if using chlorinated tap water?
chlorinated waters job is to kill all bacteria, good or bad.

unless you have a reverse osmosis filter or using rain water you have been wasting your time.

Chlorine is an essential trace element for plants. Unless your specific tap water in your municipality is highly chlorinated like pool water (like way over 2.0 mg/L) it likely doesn't impact the bacteria in your soil much, and will definitely not sterilize it. This video is rather interesting:

collected rainwater or if there isnt enough rain, I have an old hot water cylinder that is filled with tap water and sits outside with a lid on it.

also use it on the vege patch,seems ok

Dammit Northwood. I was all ready to reply to this and you said it all. Op your grow looks great. Keep it up. I defoliate my plants around this time. Cut off the really big fan leaves.

Great to see that you solved the issues with the burnt leaf tips! The new growth looks great. I think you can definitely look forward to a nice harvest on this one. :weed:
thanks mate,your help has been what i needed to get these going,its only the first cycle so will see what happens. if they struggle and are small hopefully the nxt cycle will be better. still reading and learning and making mistakes but its all fun interesting.

i always thought chlorine in water will kill them too(bacteria).this video kinda says otherwise.very interesting.

Ratshit guys ive got some sort of bug on my ladies, I reckon its spider mite. start of week 3 flower.

I've taken a few damaged leaves and clean them up a bit.

I've sprayed with soapy water and a little bit of neem and seaweed at different days. Ill stop the neem tho as ive been advised. Will have to wait and see.

By the looks of that leaf, it could very well be spider mites. Have you seen them? I'd scope underneath some of the leaves in affected areas for a positive ID to confirm what you're battling. The worst thing with spider mites is that they often multiply unseen, then it's like overnight that your grow becomes infested with webbing everywhere. You mentioned no webs, so either you're in the early stages or they aren't spider mites.

The soap will hurt their ability to breath properly, and although it likely won't kill them, it will at least help keep their numbers under control. Forceful spraying of all the undersides of the leaves will knock them off too as well as raise the humidity (which they don't like). Keep lots of air blowing around in the tent as well, and try keep your temps under 30 C. Spider mites thrive in still, hot dry air. If the species of spider mite wasn't introduced by another cannabis plant and instead tracked indoors from outside, it's likely something that isn't adapted to cannabis and might be easier to manage. Sometimes even by fixing environmental parameters you can manage to control them if that's the case.

If they start to get worse, you may have to take more drastic action such as alcohol (ISO) and water mixture spray. Keep in mind this will hurt the leaves to some extent, so only do that as a last resort. Got any ladybugs available? There are other predatory mites you can buy for them as well, but a friend of mine who tried it found they weren't very effective. Anything is worth a try though when it comes to predators. Just find out what's available or what you can catch in your area.
