Possible lack of water/nute. Advice? (PicS)

[JediSmoker]

Need advice please.

I am using ebb and flow system, 400W MH, PH 5.6, H202, Nutes "as directed". I flood every 5 hours, (4x a day) untill fill, then drain (takes 4 mins)

It seemed the same thing happened a couple weeks ago when I was at 1/2 nutes. I then cleaned the rez, went full nutes and they perked up some. The last week or so they have gotten worse ... I cleaned/refilled the rez yesterday with no improvement.

Any advice would be great, really dont want to lose them.

id say you need to flood about every 2 hours when lights on, once when lights off.. extend the watering time to about 10 mins at least.

you dont have burnt tips really so its not a fert problem, and if your ph consistantly stays in the mid 5s then you should be good there too. thats why im leaning towards a watering problem.

what nutes are you using and do you have any idea of ppms?

I am using BluMoon veg solution, and no I have not yet invested in a PPM meter yet so I dont actually know. According to the directions I should be at 1400-1500PPM.

The leaves are a solid green, I have seen burnt plants before and my plants look nothing like it. The leaves look "rigid" and the new sprouts on top are curling slightly.

Yesterday I upped the watering to 6x a day (every 3 hours) for 15 min. each time to make sure the roots get pleanty of water and nutes. I think this morning they are already looking a little better. I will provide more feedback/pics when I see a change for the better or worse.

Thanks for the help, so far this site rocks.

What are u growing in? I use rockwool in a ebb & flow and never had to flood more than 3 times a day during flowering but im only 4 weeks in on that system.

Thanks for the reply.

I started out in 1" rockwool from seed, and when the roots started poking through I planted them in 6" net baskets with clay pellets.

I believe the plants are not using the rockwool anymore because the roots are now poking out the bottom of the basket. With that, I believe they are not moist enough only being watered 4x a day for 4 mins each.

Even now they look "healthy" and green, just "lazy" and rigid with slight curling.

you need to go get a ppm meter because first, if you were at 1500ppms i would think you would be burning the hell out of your plants. get a ppm meter for sure, you can get a tds pen for like 20 bux. they look pretty good tho just droopy. are you sure the roots are getting submerged? also i have never heard of those nutes but i would reccomend getting some that are mainstream and are used a lot for cannabis... GH, canna, PBP, bontanicare, advanced, etc.. might be a little more suited for your application
