Leaf damage? Dtw coco

Ok was in a hurry but got a better pic. Learning to act early and this means something for sure.

So the bigger plants are a week potted earlier and thus is rootbound to point that its giving me drip issues. Its really because the pots are too full of coco but just a note I dont this the others have the same root system density.

Took a closer look at the other clones I dont see this burning. Just the very tips which I heard is the perfect balance of pushing it good but not too far.

About to test runoff if its higher than there ya go.

Inflow 1.8ec, runoff 2.3ec I need to lower it about .3ec I originally thought and turned out to be about right. What yall think? Lowering to 1.5ec or should I do 1.3ec? I think 1.5.

Edit See Im starting to figuring it out! Dtw coco is pretty easy only a few boxes to check to dignose issues. To where even I can start to figure it out.

Theres members that discurage checking runoff but I had to last couple times to figure it out. Now do you think they were overfed from the start that maybe I was just few points too high?

Out of anxiousness not waiting to see if 1.5ec is enough? Or was it good, because they looked great and still do aside from two clones which are bigger. A week older. The rest dont have this but could be catching it soon enough.

Health check. Same conditions. Week 8 just started. Chop at wk 9 or 10. 11 would be least likely but possible. Flipped the mother prematurely so ive been mentally preparing for 10 wks.

Some spots on few leaves on right plant the left one. only has one or two like that. A bit progression of tip burn and some more on side ridges. Not sure if its from being too late to drop ec or still need to. 1.5ec.

Hows it looking? Whats it from? Am I doing alright still?

Quick question do white larf buds ever ripe? I grown two plants now to the very end even the first nugs on the plant next to the ground no white hairs. Fully expressed. Was well lit in that area.

What about if its dark there and white/yellowed larf? Is it like foxtails that they can go longer than typical if less optimal down there?

I had foxtail once made an auto go over 20 wks, the larf area just kept going too. But then two plants one auto that was well done.

Is that the true end or is it done if it is done down to the areas youd normally prune off? I avoided any stress due to seeds last time.

Im on week 8 the mother ran to week 11 but possibly half week over ripe and may of been half week longer to switch due to premature so I thought week 9.

Looks like 10 weeks is the harvest but wondered could the mentioned question effect harvest date?

If it goes to week 11 idk how it would change from the mother from seed considering it for sure took longer to bud and left to ripe over a week passed all orange hairs.

The tops are all done all the way to where its shaded im literally just waiting on the little bit rest there is and the larf area. Like 80% done.

Shoot, those spots are coming faster now several leaves each. About to check runoff. Love the fact I got 3 other clones in slightly different enviorment and they do not have any spots like this. Helps diagnose seems like.

Fed 8x a day every 3 hrs. PH 6.0 but sometimes gets to 6.5. Try let it drift but using color test drops its tough Im just now getting good at just keeping it at 6.0.

8x a day if I feed even an hr early it overfills out the top thus indicating dry back. It soaks the drip half the run time then puddles and rises to the tip of pot.

Feed early it puddles instantly and over fills. Had I not overfill the pots I may of not noticed I needed 8x a day vs 6x. 6x could be too much dryback which killed my plant once, never again.

Lights too strong? No bugs. 75F - 80F day 60-65F night 45-55rh. 600-900ppfd mars hydro ts1000 24” or so away whatever got it to say 900ppfd tops 600ppfd lowest bud sights in top of canopy thats pretty flat.

The plants in dimmer lighting dont have those spots but theyre smaller plants and couple weeks younger. 1.5ec with .5ec being tap ever since I thought I was over feeding at 1.8ec.

The spotted plants the worst one is 1.55ec and a random plant of the three 2x2 plants is 1.58ec so theyre hungry, no? Would like to hear from the community.

Edit I weighed it through I think Ill go up one point and check runoff at chop to see how they respond. May of dropped ec lower than I needed like I suspected.

Kinda acting on any sign of change when by the time I see it it could be from the action before the last one that caused it.

Just gonna go through this again and again and act slower, having grossly underfed plants fixed and flipped within three weeks or less is unlikely. Over shot it probably by one or two points. .1ec that is.

Progressing. 2-3wks max until chop. Its about to look worse than the mom and I messed a lot of stuff up. I babied these and this is unfolding quick. The other half of garden is ok no spots like these.

Going to up ec 1.5 to 1.6 and really might not figure it out in time. Welp still a pretty good run.
