Leaf problems, need help! Pics!

Running 2x 10 gallon bubble buckets, start of week 2 flower. 2x600w lights. Have had a few grows through this box and this if the first time I have seen this type of damage.

I seem to have a few different leaf problems this round. Has me a little worried.

I first started noticing the new growth was a lot lighter and almost yellow looking. Tops of the plants are clawing inward also. Figured the plants needed more oxygen so I added another air stone to each reservoir. They seemed to perk up a bit but they still have a droopy/wrinkled look.

Consistant damage throughout the plants, has me pretty worried.

I was think the bucket size may have something to do with it, but there is still a lot of room for roots. I am going to get them bigger buckets by Friday.


The on these is consistent with other leaves on most of the plants. Seems to be yellowing along with it.



See the yellow discoloring in the leaves above?

Above seems to be the plant with the most curling of leaves.

Above is a shot of each bucket. The plant on the left in the first pic I think is just N deficiency, because its yellowing seemed to start at the bottom. I could be wrong though.

Above is different affected leaves.

It seems even after this long I still don't have shit figured out. Every harvest I seem to come across a totally different problem than the last. And the more I search for answers the more possibilities I come up with and I don't want to treat the wrong illness.

Any input greatly appreciated! Educated guesses are alright also!

Roots healthy or slimy? Water source and ppm? Nutrient regime and ppm? Ph levels? Scoped both sides of leaves? Light source?

Healthy roots. RO Water. Not sure ppms. Might be my ph it is a little high, close to 6. The damage seems to be on the tops of the leaves only. Light source is 3.5 feet above plants. 600w inline above each bucket. I had them closer to the light but I lowered them after I added the airstones because I read it could be from heat stress/low oxygen in water.

You're adding back cal/mag to your RO water? If so that leaves nutrients to examine. What are you feeding them and at what ppm? What is the medium in your buckets? Sure looks like something is locking your nutes out...

Does this help you at all? Sorry, too wet behind the ears to offer an opinion. G/l!

What can I do to add cal/mag back to my water? I haven't had to before...

I am not sure the ppms, I use a light nutrient schedule and haven't really had to worry about it until this grow. I use heavy 16 A&B.

Should I run straight water to flush them out or would this just make the situation worse?

You can go to a grow store and purchase some cal/mag to add to your RO water or do an amazon search for it. I'd also recommend you get a TDS/EC meter and start recording your nute levels. Essential for hydro to know and chart your ppm so stuff like this can be figured out a little more easily, or avoided.
