I feed every other week some times every two weeks. I put some MG flower spikes in and used 3/4 of what they said on package. Also i have used Flora Nova again, Just used 1/4 strength every one to two weeks, fluched twice before this happened i think it may be heat or N because no yellow any where. just crazy claw look. Ph is 6.5 i tested soil this morning temps are about 80 and i had fan on floor blowing up but i opened doors and proped fan on a chair so it is up higher.
