Marks On leaves, please help.

Hi,

Im late into flowering and some problems are appearing on my leaves. I was wondering if you guys could help:

Plant A


Plant B


Both plants are different strains and the markings are different. On plant A the marks are from the edges inwards and Plants B has random brown markings on a few of the leaves. The problem is on very concentrated, but i thought I'd better ask you guys for help as im only a few weeks away from harvest.

About 3 weeks ago I adjusted my Ph to 6.3 from 7+ as I purchased a ph pen and didnt realise how far off i was with the litmus test. From then on my plants just started to bloom exceedingly fast. But the markings on plant A have started to appear this week.

Any help is appreciated

Thanks

It's a hp problem 5.8-6 also looks like a bit of burn, heighten the lights

Thanks for the quick response. Do you mean my ph should be between 5.8 and 6? Im growing organicaly in soil.

6.8 soil unless coco. Look under leaves for mites and look like burn/lock out.

Oh no! What should I do? I would say my plants are 2 weeks away from harvest? Could i just continue as normal until then?

Thanks

Flush for the next 2 weeks then chop. It's just burn on the top pic and what looks like mg deficiency on the bottom one. Let them get good and yellow before you chop and you won't regret it. BTW 6.5 is where your ph should be in soil.

Thanks,

Im gonna give them one more normal feed then just flush with plain water for another 2 weeks after, so 3 weeks in total befor chop. One of my plants has mainly cloudy trichomes and the other 2 are about 3/4 of the way there. I'll post some pics of my babies soon and i'll let you judge if there ready.

Peace

Good luck and do look under the leaves. Post pics of the harvest bro.
