updated (with HPS off) what kind of deficiency? newb. help me lord.

[HR][/HR]Strain: Bubba Kush ( got as clone)
Current state: 5th week VEG
Temperature : 80F constant
Humidity: 55%
Airflow via wallmount fans
co2 750 ppm during veg (slight i know)
lights: 1000w HPS
soil: promix in 5 GAL pots.
Nutrients: DNF 2 part grow A and B. Cal-mag. Root Enhancer. B1 booster. GH diamond nectar (humic fulvic acids)
water: RO water
PH when feeding: 6.0-6.3
Schedule: Feed. Feed. Water.

now that I have given you some background info. Can you please tell me what kind of problem this is? I checked my soil ppm and it was around 400-500

I checked the soil PH and i gave it water at around 7.0-7.4 and run off came in the low 5.0-5.8

SO.. was this a PH problem. or is this something like root aphids? what signs of deficiency are being shown here?

Everything was going good then i started to notice the nice dark green colour of the leaves slowly fading and its not just at the bottom its starting to take the whole plant. I have included some pics. I appreciate your help and I will check to answer any questions!

Thank you. You are truly a great help

see 5th week of veg and a clone, what if the clones was already 5 weeks old, then in fact your plants would be 10 weeks old, see the diff, whenever anyone grows out clones all they are doing is growing out other growers issues, as the clone is a clone of a much older plant, extreme caution here ...lol however your plant is needing to go to bud, but first wash those excess nutes from the rootzone by doing a flush ....to my blog:

should i flush then put it into bud. or flush and then feed it one more time with half nutrient strength?

I would wait till they are perked up before flower. you bud those now and your harvest is going to shit the bed!!

Fuck I cant believe this has happened to bubba kush, tragic. This major issue was hard to work out, all I can think of is some sort of disease in the root system or the clone you have (the mother) is unstable and all her clones do this at this stage. I can see they were going so well . Now they are fucked my friend.

Those plants look like they are drowning/severely overwatered. If that isn't the case then the soil for some reason is toxic and they are shutting down.

Have you let your soil dry out before watering/feeding. The top two inches of soil should be dry when you water/feed again as the soil and roots down lower will still be semi moist.

Flush, allow to recover then to bud in 2-3 day times, but on the last flush I'd mix in 2 teaspoons of Epsom Salts per gallon...to be safe..... get ready for your budding nute remap,

Careful. If they are over watered and the roots are suffocating they will only continue shutting down with any type of flush. Get back to us with how wet that soil is and how it all started.

Looks over watered and either not enough nitrogen or PH lock out for Nitrogen.

I dont like feeling the top 2 inches of medium as mine will dry from lights etc and bottom of buckets are still wet. I prefer to stick my finger in the drainage holes in bottom of bucket. It works best for me.
