We got 2 plants on a hyrdo set up (see our journal for more info) and they are into week 5 of flowering.
The top leaves of the cola are slightly burned on the tips OH NOES!
there is only 75% bloom nutes in the resevoir and we got the NFT running water across the roots 1 hour on, 1 hour off and then a 6 hour break at night to gather oxygen or whatever. We mist the plants on a regular basis (we use about 1 litre a day of ph balaned water from the tap).
Could it be nute definciency? or maybe a Ph problem? remember they are flowering. we keep the water at about 5.5ph, slightly acidic, as this was the advice taken from other hydro growers. should i change the ph to maybe 6.5? i maybe i need to flush the roots with pure water.... that would be a problem as we would have to take the res off and throw water over the root matt and these girls are about 5' tall monsters; really hard to move threm through danger of bending them.
anyway, we neeeeed your help MJP
