need some advice please

5 1/2 weeks into flowering/ 2 plants in a 19 gallon rubbermaid are starting to develop these marking on them. i have 2 others in another 19 gallon and they dont have this problem. temp ranges from 62-77 degrees F. ph 5.8 ppms 600-700. recetnyl made a switch from supernatural bloom aque to G&H floranova and liquid kool bloom. i also add sledge hammer and ph down. thats it. did a full flush friday. +++

this is what they are looking like tho right now..

pic 2 looks like overfert and maybe nitrogen burn between youre veins, have the other 2 that have no damage to the leafs on the same ec, and are they the same pheno, are they in a slightly warmer part of youre room, ect ect,

I did have the ppms @ 1000-1250 before I made the switch. I have 2 fans blowing on them. It's like a fridge in the room, feels really good in there. Light is like 22inch above them. Yup I cut them all off a white widow mother plant. Thanx for the feedback

I've seen wind cause this, was there a fan close or on high speed?
Most weed can handle 1250 ppm's

Can I pull the leafs off that look like that? Will it stop bud growth?

Oh shit I do have one really close on that side. And all the leaves are looking all weird in that spot too. Nice one!

Windburn, and a definite overfert... Turn fan speed way down and lighten up on the nutes, and whatever else. Hope your running oscillating fans ...

If i were you, i would look into Jacks Professional nutes, and calcium nitrate, and toss the rest, including ph up and down. Its all you'll ever need if your water is acceptable. Good luck. Less is more.

thanks! its definitely not an oscillating, its a 10$ fan i got at walmart. its really close and just blowing at them all day lol.. i shut it off. i have another one further away from them on low. im using tap water so the ph down is a must. ill definitively keep those nutes in mind for the next run

Yea, the constant wind will burn the leaves, and make em all crispy. A single oscillating fan on a low or medium setting will be sufficient. Do you have any idea what your tap waters ph and ppm reads?? I use everyday tap water 7.0 ph with 40 ppm and thats all i ever use. Nothing else, except for Jacks hydroponic nutes, with the required calcium nitrate. I dont even have to check the ph. No ph up or down required. Take a look at my avatar pic.. it speaks for itself. Jack's professional hydroponic nutes are EXTREMEMLY cheap in cost, but the outcome is mindblowing. And i have used em all(different nutes) throughout the 13 years of growing. Nothing even comes close. Nothing... Take care.

haha jezzzz! that avatar pic is unreal that rootball looks like a bee hive gawww, more roots more fuits... so yeah you're pretty lucky to be getting reverse osmosis water through the tap lol or maybe you're house has a filter on the main line or somthing. thats awesome tho. my tap water ph is at 9.0 or higher. the purple top gallons of water at the groceries stores are at 7.0 and low ppms, but i cant be going in there buying 14 gallons loll.

ppms like at 180-200 in the tap water

With a flush already done and the fact your in your 6th week I would start to taper off the nutrients and watch them. The tips show you have been hot for awhile so maybe drop your reservoir by 100ppm or so. Ph could also play a role, I would not let your swing get out of range. ph balance your res at 5.6 and let it swing no further than 6.2 before re-adjusting. This would be the max swing you would want if you can keep it tighter you can. Good Luck
