It doesn't matter if they run "clear", you need their EC to be close to the water you'r putting in.

If it is over 30°C outside it would require more than a fan to cool it below 30°C inside - you'll need an air conditioner. I wouldn't grow most strains constantly over 28°C.

You should get around 0.2-0.4 (strain dependent) mS (mili Siemense, a measure of EC, electric conductivity) of magnesium and calcium in your water. I wouldn't add excessive sulfur as it kills fungi in the medium. Maybe not at first but it occumulates. I would def. not reuse the medium for long...

Sea of green with high yielding plants. Aiming for a pound of A+ grade weed out of a 600W is a much more interesting challenge if you ask me ;-)

What's your medium, nutes and strains?

Yep. It just burns a certain part. It will not be as effective but it's usually only a small portion that gets the bleaching.

Yes. Added a picture of a 7 gal fabric pot grow. I used quite a large variety of pots by now... Currently use 7 gal and 20 gal fabric pots (and a lot of plastic pots).

It's a heavy sativa, I would expect a long flowering time on this one. There is absolutely no way of guessing the strain by the picture.

I wouldn't move the plant until the root ball can lift most of the soil while transplanting. And after that stage there's no sense in trashing a perfectly good pot.

What are your max and min humidity levels?

Congratulations! Are they indoor or outdoor grown?

I use powdered humics and compost teas. Highest quality I found, and also one of the cheapest.

That's a cannabis plant. Soon it should show sex - check if it is a male (trash) or female (keep and love).

I would transplant once the plant requires a watering more frequent than once every 3 days. The final size will depend on how long you vegitate your plant.

33% peat, 33% highest grade possible compost, 33% perlite or another aeration agent. Add a cup of pelleted horse manure or half a cup of all purpose high grade guano per 50L of mix to cut your fertilizer needs at least by 50%.

It is not, but did you soil mix had any? If not, you plants should fade roughly 7 days after a serious flushing of the medium to remove any nutrient leftovers. The Ionic liquid fertilizers are fast release fertilizers.

The C99 stock from female seeds is a F2 of an already highly unstable genetics, one would expect quite a few oddities to show in the progeny. Such yellowing might occure do to other reasons but finding the culprint would require a picture of the whole plant and a bit more details on the grow and...

The humic acids are good food for microbes that come from the kelp. You can get the microbes from other sources though

If you have slow release nutrients in your medium you simply can not flush it and the plant will not fade until the fertilizer runs out In soil less medium 4-5 days are usually enough to see some fading.

You will need a vent and ducting at the matching diameter. Fix the ducting in place with zip ties and cover them with a good duct tape. To cool an adjust-a-wing you can fix a small clip fan on the reflector itself to blow the heat away from the bulb. It doesn't cool the room as good, but with...
