thank you going to post pics.... but im going to try giving them straight RO water for the next few days.... Anyone think i should try giving the plants a half ass flush with maybe just a gallon or so to each plant?.....

have a few plants where the a few leafs are turning yellow at the tips and also curling up on the edges..... think it might be a deficiency but not sure, they are about 2 weeks into flowering ....Help needed!

Thank you. That's an absolutely fantastic idea. I'll look into getting an air purifier for the area. :)

Update: Day 2 after my first post. There doesn't seem to be any mold yet. I'm keeping humidity below 50% and I haven't watered. I'll be watering with 3/4 of a gallon between 12 plants.

Alright, I'll let them dry out. What should the humidity be at? I thought 60% was a good range for beginning of the bloom cycle. Since the discovery of mold, I've brought the humidity down to 50%.

Update: It turns out there was mold growing on the bottom holes of all but 2 or 3 of the plants. All the visible mold has been removed. Fan is on high and circulating lots of air.

85% soil, 15% perlite-like rocks

Watering is done 3 hours into the 12h-light cycle. This is a bad deal :(

If you put your girls in larger pots the humidity will stay higher.

well first off they have long outgrown those 20 oz cups.. You need to get them into much larger pots, probably 4 or 5 gallon would be best right now. But your roots are all interconnected in the cup nd probably need help being broken up during the transplant process. Your cups are the reason why...

So i transplanted my girls into their 5 gallon buckets today and the move didnt go so well; lost some roots and was not as easy as i thought. Will the lose of roots cause much damage to the plants, or do they just need time to repair and if so what is the best way for them to repair? maybe just...

I have seen that a lot of people are curious as what to use as water for their plants so this is my suggestion. RO is nice but does not have anything in it can be good and bad. My suggestion is to try using half RO water and half tap water just so you have a few minerals in the water. Try...

I would try to get my hands on RO h20, and try to relieve stress from the environment this should help

https://www.rollitup.org/view.php?pg=faq , look here it seems to me there is a nutrient problem, try getting a nutrient that has enzymic reactions to help with the efficiency of the plant.

decided to get cal mag plus..... the reason i determined for this deficiency was using RO water. Have decided to start using some tap since it has iron in it normally. thanks

I currently have 5 plants that appear to have an iron deficiency. Diagnosed because the top leaves are turning slighly yellow and the bottom ones are fine and green. How do i fix this problem ?, is there something simple to add or make that will solve this? any help is good help:joint:
