New Grower Something Must Be Wrong, first grow, leaf tips yellowed

[Dominas999]

Morning folks, so this is my first grow and am now on day 60 and nicely into harvest...

Full details on the setup are

75.F

35%RH

250 watt HPS

10" fan

Compost, light soil and a touch of sand grow medium (have purchased bio-bizz all mix for next grow, big Buddha chiesel fem at day 7 will post journal soon)

Run off PH is now at 6.0

Feeding schedule is once every 3 days (Flora Bloom,Flora Micro, Cal/Mag).

About half way through my grow I noticed the very tip of the leaves (talking 1mm) were yellow and slightly brown...

I kept an eye on the situation and it hasnt really got any worse but is literally on every leaf tip, fan leaves and sugar leaves...

Now she is a very small plant but I am more concerned with learning on this grow as opposed to yield (obv the denser and danker the buds the better) she is 1ft tall and a small 9 inches wide, but her first 23 days were on a window sill...

Some pics below the close up is of the yellowing leaf tips, just want to know whats causing it as I want my plants to be at their best but this tells me it isnt..

The clawing I have been advised is too much Nitrogen intake and will reside during flowering, how can I prevent this in future, is it nute related,temp,humidity??

Apologies if any info is missing or babbling on but thanks for reading and any input is welcomed.

Thanks again :group:

You didn't say what strain your girl is,but she;s not looking to bad.Your ph should be around 6.5.Your rh should bea little higher at least 50 %.There not much you can do for her now. Try and get your RH higher and cut back on nute doses for your next grow.

Sorry she is an Autowembley from Pyramid seeds NL X blueberry I believe... I will adjust a few things to raise RH, raising PH can be done no problem... Thanks Namvet you have helped me alot on my first grow...

The burned tips and the clawing go hand in hand. Both are signs of overfeeding. Depending on your pot size, feeding every 3 days may be a bit too much. Generally speaking most auto strains won't tolerate more than about 1/2 the recommended nutrient strength. Get a feel for the weight of your pots when they are almost completely dried out. Only feed/water when they feel that way.
