New growth is yellow.
Res is full of algae.
PH is too hi.
The top of my plants are turning yellow. When checking the PPM and PH I noticed algae in the mix, and the PH is too hi. So I flushed the system, moved the babies to a holding tub (soon to be a clone bubbler) and cleaned the entire setup.
Added seven gal. of water. Balanced the nutes at 500 PPM, and lowered the PH to 5.5. Placed the plants back in the Aerospring and turned on the pump.
I will check it again tonight. This grow has been strange from the beginning. When I germinated the seeds, several cracked, some of these started to sprout then seemed to go dormant. So I placed them in the Aerospring to see if they would start to sprout. Of these ten...seven sprouted. Three of these did not grow and were discarded. of the remaining four only two look like they might have a chance.
Time will tell. |
