I'd agree with this, 40 days won't be enough to finish.

That looks to me like a slight calcium deficiency along with a potassium def. Both need to be corrected quickly, but the potassium will get really bad if you don't act fast.
I'd drain and clean your reservoir and mix a new batch of solution including cal/mag, and make sure your pH is on point.

It really depends on what's causing it, you could have too much of one element that's locking out K, or it could be pH related, or you may just be running your nutrients too light. It's hard to say without knowing all the details. You could try giving them a quick foliar feed with a bloom formula and add some cal/mag, it won't hurt them.

Actually, I would lower that down to around 800ppm and gradually work up to about 1100 during peak flower. How long ago did you mix that batch?

Is that an aero or a dwc that they're in? What size net pot is that? If that's a small pot, those roots should be much larger by now. Gotta run, I'll check back later.

Its an Ebb and Flow man, / Flood and Drain . 6in wide pots about 4in deep.
Water turns on 6x a day. 3 hours apart. Fills for 5 minutes (Fills to top) and drains.
Going to lift up the lights and do a foliage spray with some bloom and water. Will post any update. When I get out of work, the lights will be off, so I won't update until tomorrow.

Well, I'm still here, have't made it out the door yet sooo...
I'm certainly no expert on ebb n flow, maybe someone else could chime in here, but it seems to me that you would want to fill up that tote with hydroton so the roots have a place to go. With it only getting water every two hours, I don't know if the roots will continue to shoot down into the res. If it were aero, you wouldn't need any additional medium, but I think you'd be much better off if you filled that with hydroton. Someone feel free to correct me if you know otherwise.

I have always seen the roots hanging in Ebb and Flow, and its only been 26 days. You could very well be right, Im just not sure. Should I use a teaspoon of Tiger Bloom to about a liter of water and spray under the leaves? You think that might help?
Its
2-8-4
I also have to work soon, would like to do something before leaving.

Honestly, I wouldn't do that with Tiger Bloom. It's pretty hot stuff. I'm walking out the door now, so I can't get detailed but I'll come back later.

Alright, well, I used grow big, its 3-2-6 , since we need K , figured it would be the best one for now. Used half of a teaspoon with a liter of warm water. Just barely mist all the leaves and brought up the HPS so it wouldn't burn. Hope it helps.. At least not make anything worse.

dude your roots are stunted at 1-2 weeks they should be 2-3x's longer ( check youtube) than that in any set up and your heading into flower. nutrient deficiencys can cause this which one im not sure but more than likely the roots arent getting the right air /nute ratio. and im willing to bet that they are too wet for too long...... but thats just an educated guess based on my own fuck ups

We are going to cut out 2 watering times. It is worth a shot, from the start we were wondering how much to water them.

I agree with wolverine. If you're in a dwc those roots should be much bigger. Have u been trimming the root? And even if that was a 5 inch net pot, the roots should still be bursting out
