Day 2 Flower Flood and Drain Newbie

Whats up everyone!

I recently switched over to flood and drain in my flower room to try and start a perpetual SOG. I have a 40 site recirculating cloner using R/O with nutrient solution at 5.6 ph 200 ppm. After 2 weeks in the cloner all clones had large white roots. I planted them in 5.5" square pots using a medium 50/50 coco/perlite and sprinkled some mycorrhizae in each pot prior to planting.

I put the new clones in the veg room for 3 days giving them 1 feeding at 680 ppm and 5.6 ph (The same nutrient solution Im providing the mothers on drip irrigation to waste system). After the 3 days, I put the best 20 clones in the flower room in my new DIY flood and drain setup. My reservoir is 15 gallon and is recirculated 24/7.

I'm us GH Flora Series, and made a nutrient solution of 1088 ppm 5.6 ph. I was following the feed chart that was provided put lowered the doses some to try in be in the lower range of the ppm scale. I believe that scale ranged between 900-1300ppm. I currently flood the table for 15 minutes, once a day, 30 minutes after lights turn on.

No noticeable changes on day 1 however, when I went to check the plants today I noticed the newer leaves were like a neon green or a very light green. I checked my nutrient solution tested the ppm and the ph. Ppm came back at 1190 with a ph of 6.8.
I added 3 1/2 gallons of fresh R/O to the reservoir and ph'ed the solution back to 5.6 with a new ppm of 830. I then flooded the table for 15 minutes.

I have attached some pictures for review but I'm thinking they might have been over fertilized.

When making up the solution for the 15 gallon reservoir I mixed up all the nutrients with 2 gallons of R/O. Was this wrong to do? Was the amount of nutrients I put in the 2 gallons of water too much?

Should I have just put the nutrients directly into the reservoir first instead of mixing them up?

Thinking back on it when mixing I felt like there was a small white cloud after adding the micro. Could I have caused some sort of nutrient block by doing this? The nutrient solution appears to have a lot of particulates.

Could it be too much light to fast? Coming from led veg room going to 1200 watt hps?

I followed the proper order of putting the nutrients in the bucket

All temps within range across the board.

Any help/guidance would be great.


Thanks

Also you ALWAYS mix calmag FIRST. stir in each part very well before adding the next. Micro, gro, then bloom.

Airwalker16,

Thank you for providing feedback and the feed chart. I was using to much nutrients based off your chart. After adding fresh R/O to the reservoir the plants appear to be looking better.

When topping off do you ph the reservoir after adding fresh R/O?

Thanks again!!

I'll check it, bit ita usually fine.

Agree with @Airwalker16 on the PPM and calmag mixing - you raised from 200 to 680 immediately and then 3 days later to 1088 - those are huge jumps.

Read your plants, it's that easy. Only raise PPM when they're asking for it. Right now, they're not. But you are also correct, there is usually an adjustment period when clones are first placed under intense lighting.

I use the same nutes you have been using for quite a few years. If you are using RO water I'd suggest raising the PH up a little bit. I like to run mine around the 6.0 range. You might be running a little too high of PPM as well. When I run my PH that low I tend to have Cal/Mag deficiencies. I think if you lower the PPM a tad and bump up your PH a little you will be fine.
