Will my plants make it to harvest?

I won't get into all the details 'cause I did that in a previous thread, "My poor seedlings." My plants are on day 68 from seed. I watered them today, and I'm wondering if they are getting enough food? I'm using earth juice grow, catalyst, bloom, microblast, and meta-k. I'm using bloom and meta-k every other watering so I don't overfeed. According to the bottles I'm feeding at medium strength. I aerate my solution for at least 24 hours and I pH at 5.8. I'm only having to water once a week. My water is about 210 TDS out of the tap and after adding in my nutrients the TDS is still less than 500 ppm. Is my nutrient solution strong enough at this point in growth? Here are some pictures of my plants today. The last picture was taken five days ago.

I have seen much worse. what I would do if they were mine. I would switch nutrients right now. a steady nutrient like a 10/10/10 will work perfect . and all the ugly brown leafs need to come off . they will survive if you switch nutrients .

Showing early signs of nute burn, water well and miss a nute turn, or go for the flush to my blog:https://www.rollitup.org/blogs/blog32237-flush-baby-flush.html

That^^

As a loose rule feed with nutes 3-4 times followed by PH balanced H20 feed. Repeat.

I had been struggling with a nutrient deficiency because of my pH being too high. My run off water was 6.5 today, down from 6.7. I just fed nutes today so next time I will use straight pH'd H20. I'm growing in Promix HP, so what nutrients would you guys recommend for soilless medium? Thanks for your help.

I doubt you have a nutrition problem due to PH. Your plants look burned, not deficient. I've seen the same thing in Pro Mix before..

What nutes are you using?

I'm using earth juice nutes. I have put these poor plants through hell. Fortunately the seeds were freebees. Oh, they have only been in these 3 gallon pots for three weeks. I checked one of them the other day and the roots are just starting to show at the bottom of the root ball.

Ok, gonna flush flush flush and see what happens. Thanks Vos and all.

68 days and that small.

Im tossing pythium due to overwatering and weak lighting out there as two possible factors.

Hey mate. Why are you pHing @ 5.8?
I thought soil needed about 6.5 pH'd water. (Depends though, where your soil's pH is at.)

Cheers!

I flushed one plant this morning and I'm leaving the rest alone for now. They are green and seem happy. I'll see what the next few days brings. Yea, I really stressed these plants out since germination by moving way too fast. I started in peat pellets, then to beer cups, then 3 gallon pots, then back to beer cups, and finally back to the 3 gallon pots. Until now, they have spent all their energy recovering from grower abuse, instead of growing a strong root base. Then I topped them to boot. So, the lack of substantial growth is understandable. They have been in the 3 gallon pots for just over three weeks. This has definitely been a learning experience, and I'll move a lot slower next grow that is for sure.

Oh, I'm growing in Promix HP which is soilless. My plants are approximately 18" under a 600 watt hortlux blue mh bulb. The bulb is supposed to be used all the way through flowering. I have wondered if I should have just got an hps bulb. I don't think it's the bulb, I think it's me. lol I'm determined to get something out of these plants, even if it's only a gram a plant. I wanted to say something else, but I'm stoned and forgot. It may be old age too.

need more perlite!

Think my plants are going to do ok. Not expecting to yeild a ton of weed, but I can't complain too much being my first grow. The plant directly behind the humidity monitor is the one I flushed. I have a bit of nute burn on them, so I'm going to feed with straight ph'd water next time. Maybe add a bit of cal-mag?

Well, my first grow turned out to be a disaster. I emptied the pots of the two smallest plants and they both appeared to be suffering from pythium (root rot). So, I decided to cut my loses and start over.

It's my opinion that you don't have burn but deficiency.....most likely nitrogen. Stop chasing the perfect PH as that's not your problem. I feed right from the tap with PH of 8.1 and have no problems (although I use soil). A buddy of mine uses the promix and feeds with Jack's Classic 20-20-20 in veg and 10-30-20 in flower and has amazing plants......and he feeds daily (1/2 tspn per gal).

Yea, I made a number of mistakes. I stressed the seedlings out by transplanting too soon. I had nutrient lockout. The seedlings had stretched, so I trimmed the lower leaves and buried the tall stems when I transplanted them. Then, I topped all the plants while they were still trying to recover from being transplanted. The promix would take a week to dry out because of no of no root structure, so the roots didn't get the oxygen they needed. I could keep going but you get the picture. Just disappointed 'cause my ex gave me the seeds and I know it would have been some good smoke.

I've got two nirvana northern light seeds in a wet paper towel right now. I'm growing them in FFOF and I've got some Jack's Classic and Bloom coming. Try not to make the same mistakes again.
