im pretty sure this is a mg deficiency bu want to throw up pics just to make sure. the clones have been in the croutons for almost a week and hardly any signs of new growth, the ppm is about 725-750 and i have been adjusting the ph daily to 5.5 but by the next day it is up to about 6.3 again. the leaves are getting more and more pale and splotchy. They are vegging under a 1000watt mh about 36" above the tops of the plants. the only other thing i could think of is the swing in my PH from day to day. please just take a look at the pics and let me know what you think and what the solution is to cure

Yeah. Clones have plenty of roots coming out of them before I transplant. There should be plenty of n in their mix but that's also what I was thinking it looks like N. light stress could be it they went from under floors to under a 1000 watt MH. temp is generally about 79 in the room and humidity is 45%. I saved 1 cut if each of those strains and planted in roots organic soil for mothers and they are looking way better than the vegging ones in my main room

here is a pic from this morning of the veg room and it seems the condition is worsening. leaves are getting really pale and darker spots mixed in. also here is a pic of the cuts that are in soil for my mothers.. they all look greatIMG_3380.jpgIMG_3381.jpg

It could be some sort of nutrient deficiency, but not sure which one. When I clone, the bigger fan leaves usually take a hit and start looking real crappy. I just usually wait for a good amount of new growth to take place and I just pinch the nasty fan leaves off, typically by that time they are already half dead anyway. You mentioned that your PH changes daily, going from 5.5 up to 6.3. I kinda feel like that is probably your biggest problem. I ran into the same problem with my PH jumping so fast, having my PH go from 5.8 to around 7 within 24 hours. It did it every single day until I just gave up and chopped before they had a chance to produce anything worthwhile, and I wasted so much of my PH down solution just to keep it in check. If I remember correctly, I think mine was due to slime building up in the bubble buckets I was running. It was the first time I ran bubble buckets, and I used those all black ones, which in my opinion are bad. The reason I say they are bad is because dark colors retain heat instead of disperse it. So, since the buckets were black, and being under two 600 watt HPS lights the bucket would transfer the heat to the water, making the water temps rise up to around 78-80, which was a breeding ground for bad bacteria. I was rinsing the roots and cleaning the buckets daily, too much hassle.

I don't know for sure if this is what caused my PH to raise every day, but with the water temps being too high it made the roots get covered in a clearish slime. I feel that the slime that built up overnight is what caused the PH to jump. It's the only thing that I could think of that was a constant factor in the problem. I could have proven this to be kinda true if I would have just transplanted them into my NFT system, which I already had broken all the way down and stored away, and see if the slime would return, but only after rinsing the roots really well and give them a good soak in some diluted H2O2. The NFT system I ran never had problems with water temps, I built it out of white PVC and a big blue tote, which I ended up spray painting white to also help bounce the heat off of it.

You didn't mention anything about having slime on your roots, so I assume your roots are fine. I know I just went through that long story and probably didn't help you solve your problem. The only thing I can say is keep an eye on your water temps, as well as your roots. My PH problems didn't start to happen until about a few days before the slime appeared, so I just assumed that was the problem. Once I went back to my NFT system, and the water temps was staying in the right range I didn't run into the slime problem, or the PH problem again, maybe it's a coincidence, maybe not.

Yeah there's no slime. I dug up to see of the roots were growing. It's been a full week and they have barely grown a half an inch. Everything is at a screeching hault and my soup should be crushing it right now. Can't figure it out

Yeah there should be no shortage of N. may be iron anyway I flushed everything and I'm running at like 375 ppm now. It's been 2 days and they are looking better. The ph still spikes like crazy. I ph my Rez to 5.5 and after 1 watering its back up to 6.2. Never had tho much trouble keeping ph balanced. I checked the run off and it's also about 6.2
