yes nothing at all.. i rekon its a potassium deficiency also it deff needs some nitrigen.. leaves are yellowing then browning,.. its only the fan leaves. but some bud leaves followed. but hey their growing.. and im using my head.buds are accumalating and im happy.ish.. its talking too long..

One more thing . every thing is eeregular. not timers..
I make sure the lights have twelve hour on . so if i wake at one lights go of at 1. if i wake at nine in the morning. then i useually turn them off before igo to bed. around ten. . ive streested them by not giving them water for days on end. and from that i think ther a wee bit hardy..

peace
