Aoa, my
melon & cucumber plants are growing very slowly in these days. Look at the Leaves. Small leaves of melon plants

. wilting leaves of cucumber plants. Moreover yellowing or browning & drying of leaf tips & edges of cucumber plants. I have done almost everything to my plants but all in vain

. I do not know what are the exact reasons behind this.
Kindly tell me the possible causes & solution. Waiting for your reply, Thanking you in anticipation.
