hydrococo 60/40 gold label
I haven't tested the ph of the medium, any good method of doing it? I have the ph pen to measure the solutions for feeds.
I'm using Dutch Pro A + B
They were watered 3 times so far (every week) as the medium seems to retain moisture pretty well and I had them in large...
Just gotta say this is my first time. My babies have started showing some yellowish spots on leaves. They are now 4 weeks old (from seed) and were last fed few days ago at EC 0.9 and PH 5.7. Any ideas? If you need more questions to determine the cause, please ask.
