Swapped bulb to hps and flipped to flower on Sunday, end of week 5.
As I have had some issues I decided to invest in a bluelab PH pen and Truncheon.
Set EC to 1.8
Set PH to 5.8
I still have some issues with the first leaves on the plants. My PH rapidly rises when it's set low but doesnt seem to go above 6.5. I have also moved all the smallest plants to the middle to try even the canopy.
Next week I intend to slower EC to 1.4 and see if that makes a difference.
Hello,
I can't understand why some of leaves are loosing colour at the tips. Sunday I mixed the nutrients, it was at 6.3 so I did not adjust. Today risen to 6.4.
Hi @NanoGrows The burns on the leaves seem to me to be PH variations. It regulates the PH of all waterings to PH 6. The discoloration between the leaf veins seems to me to be a calcium deficiency. good luck mate 👍
